1Chapter 01: Nursing Practice in Canada and Drug TherapySealock: Lilley’s Pharmacology for Canadian Health Care Practice, 4th EditionMULTIPLE CHOICE1.Which is a judgement about a particular patient’s potential need or problem?a.A goalb.An assessmentc.Subjective datad.A nursing diagnosisANS:DNursing diagnosis is the phase of the nursing process during which a clinical judgement is made about how a patient responds toheath conditions and life processes or vulnerability for that response.DIF:Cognitive Level: Knowledge2.The patient is to receive oral furosemide (Lasix) every day; however, because the patient is unable to swallow, he cannot takemedication orally, as ordered. The nurse needs to contact the physician. What type of problem is this?a.A “right time” problemb.A “right dose” problemc.A “right route” problemd.A “right medication” problemANS:CThis is a “right route” problem: the nurse cannot assume the route and must clarify the route with the prescriber. This is not a “righttime” problem because the ordered frequency has not changed. This is not a “right dose” problem because the dose is not related toan inability to swallow. This is not a “right medication” problem because the medication ordered will not change, just the route.DIF:Cognitive Level: Application3.The nurse has been monitoring the patient’s progress on his new drug regimen since the first dose and has been documenting signsof possible adverse effects. What nursing process phase is the nurse practising?a.Planningb.Evaluationc.Implementationd.Nursing diagnosisANS:BMonitoring the patient’s progress is part of the evaluation phase. Planning, implementation, and nursing diagnosis are notillustrated by this example.DIF:Cognitive Level: Application4.The nurse is caring for a patient who has been newly diagnosed with type 1 diabetes mellitus. Which statementbestillustrates anoutcome criterion for this patient?a.The patient will follow instructions.b.The patient will not experience complications.c.The patient adheres to the new insulin treatment regimen.d.The patient demonstrates safe insulin self-administration technique.ANS:DHaving the patient demonstrate safe insulin self-administration technique is a specific and measurable outcome criterion. Followinginstructions and avoiding complications are not specific criteria. Adherence to the new insulin treatment regimen is not objectiveand would be difficult to measure.DIF:Cognitive Level: Application5.Which activitybestreflects the implementation phase of the nursing process for the patient who is newly diagnosed with type 1diabetes mellitus?a.Providing education regarding self-injection techniqueb.Setting goals and outcome criteria with the patient’s inputc.Recording a history of over-the-counter medications used at homed.Formulating nursing diagnoses regarding knowledge deficits related to the newtreatment regimenANS:AEducation is an intervention that occurs during the implementation phase. Setting goals and outcome criteria reflects the planningphase. Recording a drug history reflects the assessment phase. Formulating nursing diagnoses regarding a knowledge deficitreflects analysis of data as part of the planning phase.DIF:Cognitive Level: AnalysislOMoARcPSD|13778330

26.The nurse is working during a very busy night shift, and the health care provider has just given the nurse a medication order overthe telephone, but the nurse does not recall the route. What is thebestway for the nurse to avoid medication errors?a.Recopy the order neatly on the order sheet, with the most common route indicatedb.Consult with the pharmacist for clarification about the most common routec.Call the health care provider to clarify the route of administrationd.Withhold the drug until the health care provider visits the patientANS:CIf a medication order does not include the route, the nurse must ask the health care provider to clarify it. Never assume the route ofadministration.DIF:Cognitive Level: Application | Cognitive Level: Analysis7.Which constitutes the traditional Five Rights of medication administration?a.Right drug, right route, right dose, right time, and right patientb.Right drug, the right effect, the right route, the right time, and the right patientc.Right patient, right strength, right diagnosis, right drug, and right routed.Right patient, right diagnosis, right drug, right route, and right timeANS:AThe traditional Five Rights of medication administration were considered to be Right drug, Right route, Right dose, Right time, andRight patient. Right effect, right strength, and right diagnosis are not part of the traditional Five Rights.DIF:Cognitive Level: Comprehension8.What correctly describes the nursing process?a.Diagnosing, planning, assessing, implementing, and finally evaluatingb.Assessing, then diagnosing, implementing, and ending with evaluatingc.A linear direction that begins with assessing and continues through diagnosing,planning, and finally implementingd.An ongoing process that begins with assessing and continues with diagnosing,planning, implementing, and evaluatingANS:DThe nursing process is an ongoing, flexible, adaptable, and adjustable five-step process that begins with assessing and continuesthrough diagnosing, planning, implementing, and finally evaluating, which may then lead back to any of the other phases.DIF:Cognitive Level: Application9.When the nurse is considering the timing of a drug dose, which is most important to assess?a.The patient’s identificationb.The patient’s weightc.The patient’s last meald.Any drug or food allergiesANS:CThe pharmacokinetic and pharmacodynamic properties of the drug need to be assessed with regard to any drug–food interactions orcompatibility issues. The patient’s identification, weight, and drug or food allergies are not affected by the drug’s timing.DIF:Cognitive Level: Application10.The nurse is writing nursing diagnoses for a plan of care. Which reflects the correct format for her nursing diagnosis?a.Anxietyb.Anxiety related to new drug therapyc.Anxiety related to anxious feelings about drug therapy, as evidenced bystatements such as “I’m upset about having to give myself shots”d.Anxiety related to new drug therapy, as evidenced by statements such as “I’mupset about having to give myself shots”ANS:DFormulation of nursing diagnoses is usually a three-step process. The only complete answer is “Anxiety related to new drugtherapy, as evidenced by statements such as ‘I’m upset about having to give myself shots.’” The answer “Anxiety” is missing the“related to” and “as evidenced by” portions. The answer “Anxiety related to new drug therapy” is missing the “as evidenced by”portion of defining characteristics. The “related to” section in “Anxiety related to anxious feelings about drug therapy, as evidencedby statements such as ‘I’m upset about having to give myself shots’” is simply a restatement of the problem “anxiety,” not aseparate factor related to the response.DIF:Cognitive Level: AnalysisOTHER1.Place the phases of the nursing process in the correct order, starting with the first phase.a.

1Chapter 02: Pharmacological PrinciplesSealock: Lilley’s Pharmacology for Canadian Health Care Practice, 4th EditionMULTIPLE CHOICE1.A patient is receiving two different drugs, which, at their current dose forms and dosages, are both absorbed into the circulation inidentical amounts. Which term best denotes that the drugs have the same absorption rates?a.Equivalentb.Synergisticc.Compatibled.BioequivalentANS:DTwo drugs absorbed into the circulation at the same amount (in specific dosage forms) have the same bioavailability; thus, they arebioequivalent. “Equivalent” is incorrect because the term “bioavailability” is used to express the extent of drug absorption.“Synergistic” is incorrect because this term refers to two drugs given together whose resulting effect is greater than the sum of theeffects of each drug given alone. “Compatible” is incorrect because this term is a general term used to indicate that two substancesdo not have a chemical reaction when mixed (or given, in the case of drugs) together.DIF:Cognitive Level: Comprehension2.A patient is receiving medication via intravenous injection. Which information should the nurse provide for patient education?a.The medication will cause fewer adverse effects when given intravenously.b.The medication will be absorbed slowly into the tissues over time.c.The medication’s action will begin faster when given intravenously.d.Most of the drug is inactivated by the liver before it reaches the target area.ANS:CIntravenous injections are the fastest route of absorption. The intravenous route does not affect the number of adverse effects, theintravenous route is not a slow route of absorption, and the intravenous route does not cause inactivation of the drug by the liverbefore it reaches the target area.DIF:Cognitive Level: Comprehension3.Which istrueregarding parenteral drugs?a.They bypass the first-pass effect.b.They decrease blood flow to the stomach.c.They are altered by the presence of food in the stomach.d.They exert their effects while circulating in the bloodstream.ANS:ADrugs given by the parenteral route bypass the first-pass effect, but they still must be absorbed into cells and tissues before they canexert their effects. Enteral drugs (drugs taken orally), not parenteral drugs, decrease blood flow to the stomach and are altered bythe presence of food in the stomach. Parenteral drugs must be absorbed into cells and tissues from the circulation before they canexert their effects; they do not exert their effects while circulating in the bloodstream.DIF:Cognitive Level: Analysis4.A drug’s half-life is best defined asa.The time it takes for the drug to elicit half its therapeutic response.b.The time it takes one-half of the original amount of a drug to reach the targetcells.c.The time it takes one-half of the original amount of a drug to be removed from thebody.d.The time it takes one-half of the original amount of a drug to be absorbed into thecirculation.ANS:CA drug’s half-life is the time it takes for one-half of the original amount of a drug to be removed from the body. It is a measure ofthe rate at which drugs are removed from the body. Answers A, B, and D are not correct definitions of a drug’s half-life.DIF:Cognitive Level: Comprehension5.The term “duration of action” is best defined asa.The time it takes for the drug to elicit a therapeutic response.b.The time it takes a drug to reach its maximum therapeutic response.c.The length of time it takes to remove a drug from circulation.d.The time during which drug concentration is sufficient to elicit a therapeuticresponse.ANS:DDuration of action is the time during which drug concentration is sufficient to elicit a therapeutic response. The time it takes for adrug to elicit a therapeutic response is the drug’s “onset of action.” The time it takes a drug to reach its maximum therapeuticresponse is a drug’s “peak effect.” “The length of time it takes to remove a drug from circulation” defines a drug’s elimination anddoes not correctly define a drug’s duration of action.DIF:Cognitive Level: ComprehensionlOMoARcPSD|13778330

26.A drug interacts with enzymes bya.altering cell membrane permeability.b.“fooling” a receptor on the cell wall.c.enhancing the drug’s effectiveness within the cells.d.“fooling” the enzyme into binding with it instead of its normal target cell.ANS:DWhen drugs interact with enzymes, they inhibit the action of a specific enzyme by “fooling” the enzyme into binding to it insteadof to its normal target cell. Thus, the target cells are protected from the action of the enzymes to result in a drug effect. Thealteration of cell membrane permeability, the “fooling” of a receptor on the cell wall, and the enhancement of the effectiveness ofdrugs within cells do not occur with selective enzyme interactions.DIF:Cognitive Level: Comprehension7.When administering a new medication to a patient, the nurse reads that it is highly protein bound. Which consequence will resultfrom this protein binding?a.Renal excretion will take longer.b.The drug will be metabolized quickly.c.The duration of action of the medication will be longer.d.The duration of action of the medication will be shorter.ANS:CDrugs that are bound to plasma proteins are characterized by a longer duration of action. Protein binding does not make renalexcretion longer and does not increase metabolism of the drug. Protein binding of a drug means that the duration of action islonger, not shorter.DIF:Cognitive Level: Application8.When monitoring a patient on an insulin drip to reduce blood glucose levels, the nurse notes that the patient’s glucose level isextremely low, and the patient is lethargic and difficult to awaken. Which adverse drug reaction is the nurse observing?a.An adverse effectb.An allergic reactionc.An idiosyncratic reactiond.A pharmacological reactionANS:DA pharmacological reaction is an extension of the drug’s normal effects in the body. In this case, the insulin lowered the patient’sblood glucose levels too much. An adverse effect is a predictable, well-known adverse drug reaction that results in minor or nochanges in patient management. An allergic reaction (also known as ahypersensitivity reaction) involves the patient’s immunesystem. An idiosyncratic reaction is unexpected and is defined as a genetically determined abnormal response to normal dosages ofa drug.DIF:Cognitive Level: Comprehension9.A patient is experiencing chest pain and needs to take a sublingual form of nitroglycerin. Where should the nurse tell the patient toplace the tablet?a.Under the tongueb.In the space between the cheek and gumc.At the back of the throat, for easy swallowingd.On a non-hairy area on the chestANS:ADrugs taken by the sublingual route are placed under the tongue. Placing the tablet in the space between the cheek and gum is donefor the buccal route; placing the tablet at the back of the throat (for easy swallowing) is done in the oral route; and placing the tableton a non-hairy area on the chest is done in the topical or transdermal route.DIF:Cognitive Level: Comprehension10.The nurse is administering medications to a patient who is in liver failure due to end-stage cirrhosis. The nurse is aware thatpatients with liver failure are most likely to have problems with which pharmacokinetic phase?a.Absorptionb.Distributionc.Metabolismd.ExcretionANS:CThe liver is the organ that is most responsible for drug metabolism. Decreased liver function will most affect a drug’s metabolism.The absorption of a drug is not affected by liver function, and distribution is not affected by liver function. Excretion is affectedonly because decreased liver function may not transform drugs into water-soluble substances for elimination via the kidneys, butthis is not the best answer to this question.DIF:Cognitive Level: ApplicationlOMoARcPSD|13778330

1Chapter 03: Legal and Ethical ConsiderationsSealock: Lilley’s Pharmacology for Canadian Health Care Practice, 4th EditionMULTIPLE CHOICE1.In the development of a new drug by a pharmaceutical company, the researcher must ensure that the participants in experimentaldrug studies do not have unrealistic expectations of the new drug’s usefulness. What will the researcher include in the design of thestudy to prevent bias that may occur?a.A placebob.Health Canada approvalc.Informed consentd.Efficacy informationANS:ATo prevent bias that may occur as a result of unrealistic expectations of an investigational new drug, a placebo will be incorporatedinto the study. Health Canada approval, if given, does not be obtained until after phase III of the study.Informed consent isrequired in all drug studies. Efficacy information is not determined until the study is under way.DIF:Cognitive Level: Comprehension2.A member of an investigational drug study team is working with healthy volunteers whose participation will help determine theoptimal dosage range and pharmacokinetics of the drug. In what type of study is the team member participating?a.Phase Ib.Phase IIc.Phase IIId.Phase IVANS:APhase I studies involve small numbers of healthy volunteers to determine the optimal dosage range and the pharmacokinetics of thedrug. Phases II, III, and IV involve progressively larger numbers of volunteers who have the disease or ailment that the drug isdesigned to diagnose or treat.DIF:Cognitive Level: Application3.A patient has a prescription for a drug classified as Schedule F. What important information should the nurse give this patient aboutobtaining refills for this medication?a.No prescription refills are permitted.b.Refills may be obtained via telephone order.c.Refills are indicated by the prescriber.d.The patient may have no more than six refills in a 12-month period.ANS:CSchedule F contains a list of drugs that can be sold and refilled only on prescription; prescriptions can be refilled as often asindicated by the prescriber.DIF:Cognitive Level: Analysis4.A patient has been chosen to be a recipient of an investigational drug for heart failure and has given informed consent. Which isindicated by the patient’s informed consent?a.The patient has been informed of the possible benefits of the new therapy.b.The patient will be informed of the details of the study as the research continues.c.The patient will not be assured of receiving the actual drug during the experiment.d.The patient has received an explanation of the study’s purpose, procedures, andthe benefits and risks involved.ANS:DInformed consent involves the careful explanation of the purpose of the study, procedures to be used, and the possible benefits andrisks involved. Being informed of the possible benefits of the new therapy, being informed of the study details as researchcontinues, and being assured of receiving the actual drug during the experiment do not describe informed consent.DIF:Cognitive Level: Comprehension5.Which is the most significant part of legislation in regard to professional nursing practice?a.Canada Health Actb.Nursing Practice Actc.Controlled Drugs and Substances Actd.Personal Information Protection and Electronic Documents ActANS:BNurse practice acts (NPAs) are regulatory laws that are instrumental in defining the scope of nursing practice and that protectpublic health, safety, and welfare. Nursing practice in Canada is regulated by separate acts in each of the 10 provinces and 3territories. These acts grant self-governance to the nursing profession, direct entry into nursing practice, define the scopes ofpractice, and identify disciplinary actions. NPAs are the most significant part of legislation in regard to professional nursingpractice.DIF:Cognitive Level: ComprehensionlOMoARcPSD|13778330

26.What potential failure is identified when a patient with a documented penicillin allergy receives 1.2 g of benzylpenicillin IV?a.Failure to assessb.Failure to evaluatec.Failure to ensure safetyd.Failure to identify the patientANS:CFailure to ensure safety includes lack of adequate monitoring, failure to identify patient allergies and other risk factors related tomedication therapy, inappropriate drug administration technique, and failure to implement appropriate nursing actions because ofimproper assessment of the patient’s condition. Whereas failure to assess or evaluate includes failure to see significant changes inthe patient’s condition after taking a medication, failure to report these changes, failure to take a complete medication history andnursing assessment/history, and failure to monitor the patient after medication administration. Failure to identify the patient’sidentity is a medication error.DIF:Cognitive Level: Application7.Which statement correctlydescribes drugs in Part G, Part II of theFood and Drugs Act?a.They are drugs with high potential for misuse that have an accepted medical use.b.They are drugs with high potential for misuse that do not have an acceptedmedical use.c.They are medically accepted drugs that may cause mild physical or psychologicaldependence.d.They are medically accepted drugs with very limited potential for causing mildphysical or psychological dependence.ANS:APart G, Part II drugs are those with high potential for misuse that have an accepted medical use (e.g., barbiturates).DIF:Cognitive Level: Comprehension8.Miss Knox, a 26-year-old, has returned to the surgical unit post appendectomy. The physician has prescribed intravenous (IV)morphine for pain. According to the Controlled Drugs and Substances ACT (CDSA), morphine is classified under which schedule?a.Schedule Ib.Schedule IVc.Schedule Vd.Schedule IIIANS:AThe CDSA is based on eight schedules that list controlled drugs and substances based on potential for misuse or harm or how easythey are to manufacture into illicit substances. A summary of Schedule I contains the most dangerous drugs, including opiates(opium, heroin, morphine, cocaine), fentanyls, and methamphetamine.DIF:Cognitive Level: ComprehensionMULTIPLE RESPONSE1.Which are elements of ethical principles in nursing and health care according to the Canadian Nurses Association (CNA) Code ofEthics? (Select all that apply.)a.Promoting justiceb.Maintaining anonymityc.Demonstrating responsibilityd.Preserving dignitye.Promoting health and well-beingANS:A, D, EElements of ethical principles in nursing and health care according to the CNA Code of Ethics include providing safe,compassionate, competent, and ethical nursing care; maintaining privacy and confidentiality; promoting justice, being accountable,preserving dignity, and promoting and respecting informed decision making; and promoting health and well-being.DIF:Cognitive Level: Critical Thinking2.The personal Information Protection and Electronic Documents Act (PIPEDA) is a federal law governing the collection, use anddisclosure of personal health details. Protected health information includes? (Select all that apply.)a.Patients’ health conditionsb.Payment informationc.Prescription numbersd.Dietary restrictionse.MedicationsANS:A, B, C, EThe personal Information Protection and Electronic Documents Act (PIPEDA) requires all health care providers, health insuranceand life insurance companies, public health authorities, employers, and schools to maintain patient privacy regarding protectedhealth information.

1Chapter 04: Patient-Focused ConsiderationsSealock: Lilley’s Pharmacology for Canadian Health Care Practice, 4th EditionMULTIPLE CHOICE1.During the last trimester of pregnancy, drug transfer to the fetus is more likely to occur. Which is a reason for this possibility?a.Fetal sizeb.Decreased surface areac.Enhanced placental blood flowd.Increased amount of bound drug in maternal circulationANS:CDrug transfer to the fetus is more likely during the last trimester, as a result of enhanced placental blood flow, increased fetalsurface area, and an increased amount of free drug in the mother’s circulation. Increased, not decreased, fetal surface area affectsdrug transfer to the fetus. The placenta’s surface area does not increase during this time. Drug transfer is increased due to anincreased amount of free drug, not protein-bound drug, in the mother’s circulation. “Fetal size” is incorrect because the firsttrimester of pregnancy is the period of greatest danger of drug-induced developmental defects. During this period, the fetusundergoes rapid cell proliferation. Gestational age is more important than fetal size.DIF:Cognitive Level: Comprehension2.Which type of dosage calculation is used most commonly when calculating drug dosages for children?a.Fried’s ruleb.Clark’s rulec.Young’s ruled.The mg/kg formulaANS:DThe body weight method, using the mg/kg formula, is the most common and reliable method for calculating doses for youngpatients. Fried’s rule, Clark’s rule, and Young’s rule are not methods used for calculating drug dosages for young patients.DIF:Cognitive Level: Knowledge3.While assessing an 82-year-old woman, the nurse determines that the patient is experiencing polypharmacy. What is thisexperience most likely to indicate?a.The patient has a lower risk of drug interactions.b.The patient takes medications for one illness several times a day.c.The patient risks problems only if she also takes over-the-counter medications.d.The patient takes multiple medications for several different illnesses.ANS:DPolypharmacy usually occurs when a patient has several illnesses and takes medications for each of them, medications possiblyprescribed by different specialists who may be unaware of the patient’s other treatments. This situation puts the patient at increasedrisk of drug interactions and adverse reactions. Polypharmacy means that the patient has a higher, not lower, risk of druginteractions, and that the patient is taking several different medications, not just one. Polypharmacy can include prescription drugs,over-the-counter medications, and natural health products.DIF:Cognitive Level: Application4.Which statement is true in regard to children?a.Their levels of microsomal enzymes are decreased compared to those of adults.b.Their total body water content is much less than that of adults.c.Their first-pass elimination is increased because of higher portal circulation.d.Gastric emptying is more rapid than that of adults because of increased peristalticactivity.ANS:AIn children, the levels of microsomal enzymes are decreased. A child’s gastric emptying is slowed because of slow or irregularperistalsis. Total body water content is greater in children than in adults, and first-pass elimination by the liver is reduced becauseof immaturity of the liver and reduced levels of microsomal enzymes.DIF:Cognitive Level: Comprehension5.For accurate medication administration to young patients, the nurse must take into account which information?a.Weight, height, age, and organ maturityb.Age, glomerular filtration rate, and weightc.Weight, height, body temperature, and aged.Weight, height, and total body water contentANS:ATo accurately administer medications to young patients, their weight, height, age, physical condition, metabolism and organmaturity must be taken into account. Glomerular filtration rate, body temperature, and total body water content are notconsiderations when administering medications to young patients.DIF:Cognitive Level: ComprehensionlOMoARcPSD|13778330

26.An older adult patient will often experience a reduction in the stomach’s ability to produce hydrochloric acid. This change willresult in which alteration?a.Delayed gastric emptyingb.Increased gastric acidityc.Decreased intestinal absorption of medicationsd.Altered absorption of select drugsANS:DThis aging-related change results in a decrease in gastric acidity and may alter the absorption of some drugs. Delayed gastricemptying, increased gastric acidity, and decreased intestinal absorption of medications are not results of reduced hydrochloric acidproduction.DIF:Cognitive Level: Application7.Which is the reason drug toxicity is more likely to occur in the neonate?a.The lungs are immature.b.The kidneys are smaller.c.The liver is not fully developed.d.Renal excretion of the drug is faster.ANS:CA neonate’s liver is not fully developed and cannot detoxify many drugs; thus, drug toxicity is more likely to occur in the neonate.The lungs and kidneys do not play major roles in drug metabolism. Renal excretion of the drug is slower, not faster, due to organimmaturity.DIF:Cognitive Level: Comprehension8.An 83-year-old female patient has been given a thiazide diuretic to treat mild heart failure. She and her daughter should be taught towatch for which complications?a.Dizziness and constipationb.Fatigue and dehydrationc.Daytime sedation and lethargyd.Edema and blurred visionANS:BElectrolyte imbalance, fatigue, and dehydration are common complications of thiazide diuretics in older adult patients. Dizzinessand constipation, daytime sedation and lethargy, and edema and blurred vision are not complications that occur when these drugsare given to older adults.DIF:Cognitive Level: Comprehension9.Which complication is common with an older adult patient who is taking digoxin?a.Hallucinationsb.Edemac.Dry mouthd.ConstipationANS:ACommon complications for older adults taking digoxin include visual disorders, nausea, diarrhea, dysrhythmias, hallucinations,decreased appetite, and weight loss. Nonsteroidal anti-inflammatory drugs may cause edema, anticholinergics and antihistaminesmay cause dry mouth, and opioids may cause constipation.DIF:Cognitive Level: Comprehension10.The nurse is aware that confusion, ataxia, and increased risk for falls are older adult patients’ common responses to whichmedication?a.Laxativesb.Anticoagulantsc.Sedativesd.DiureticsANS:CIn older adults, sedatives and hypnotics often cause confusion, daytime sedation, ataxia, lethargy, and increased risk for falls.Laxatives, anticoagulants, and diuretics may cause adverse effects in older adults, but not the adverse effects specified in thequestion.DIF:Cognitive Level: ApplicationlOMoARcPSD|13778330

311.The nurse is trying to give a liquid medication to a 2-year-old child and notes that the medication has a strong taste. The best wayfor the nurse to give this medication to a child is toa.Give the medication with spoonfuls of sherbet.b.Add the medication to the child’s bottle.c.Tell the child you have candy.d.Add the medication to a cup of milk.ANS:AUsing sherbet or another non-essential food that makes the medication taste better is the best way to give a strong-tastingmedication to a child. Adding the medication to the child’s bottle is not correct because the child may not drink the entire contentsof the bottle, thus wasting the medication. Telling the child that the medication is candy is not correct because using the word“candy”with drugs may lead to the child’s thinking that drugs are actually candy. Adding the medication to a cup of milk is notcorrect because the child may not drink the entire cup of milk, and the distasteful drug may cause the child to refuse milk in thefuture.DIF:Cognitive Level: Application12.For which cultural group must the nurse respect the value placed on natural health products, the use of heat, and a concern for thebalance of opposing forces that lead to illness or health?a.Hispanic Canadiansb.Asian Canadiansc.Indigenous peoplesd.Black people of African descentANS:BSome Asian Canadians believe in yin and yang, which are opposing forces leading to illness or health, depending on which force isin balance. Other health practices for this cultural group include belief in the use of heat and in the value of herbal remedies.Hispanic Canadians, Indigenous peoples, and Black people of African descent do not typically engage in these practices.DIF:Cognitive Level: Comprehension13.A nurse is assessing an older adult Indigenous woman who is being treated for hypertension. During the assessment, whatimportant information should the nurse remember or expect in regard to culture?a.The patient should be discouraged from using traditional remedies and rituals.b.The nurse should expect the patient to value protective bracelets and herbal teas.c.The nurse should remember that the balance between body, mind, andenvironment is important to this patient’s health beliefs.d.The assessment should include information about cultural practices and beliefsregarding medication, treatment, and healing.ANS:DAll beliefs need to be strongly considered to prevent a conflict between the goals of nursing and health care and the dictates of apatient’s cultural background. Assessing cultural practices and beliefs is part of a thorough assessment. The nurse should not ignorea patient’s cultural practices. Protective bracelets, use of herbal teas, and balance between body, mind, and environment do notdescribe beliefs and practices that usually apply to this patient’s cultural group.DIF:Cognitive Level: Application14.Which ethnocultural group believes in harmony with nature and views ill spirits as causing disease?a.Black people of African descentb.South Asian Canadiansc.Filipino Canadiansd.Indigenous peoplesANS:DIndigenous peoples believe in harmony with nature and view ill spirits as causing disease.DIF:Cognitive Level: Comprehension15.Which contributes to drug polymorphism?a.The number of drugs ordered by the physicianb.The patient’s drug historyc.The patient’s age, sex, and body compositiond.Different dosage forms of the same drugANS:CA patient’s age, sex, size, and body composition are some of the factors that contribute to drug polymorphism, which is the effectof such variables on how an individual absorbs or metabolizes specific drugs. The number of drugs ordered by the physician, thepatient’s drug history, and different dosage forms of the same drug are not factors that contribute to drug polymorphism.DIF:Cognitive Level: Comprehension16.Which best describes drug polymorphism?a.Cultural and genetic effects on drug metabolism and excretionb.Gender and cultural effects on drug absorption and distributionc.Age or body composition effects on drug absorption or metabolismd.Multidrug use resulting in impaired excretionANS:CDrug polymorphism is the variation in response to a drug because of a patient’s age, sex, size, and body composition.DIF:Cognitive Level: ComprehensionlOMoARcPSD|13778330

4MULTIPLE RESPONSE1.Which is true regarding young patients? (Select all that apply.)a.The levels of microsomal enzymes are decreased.b.Perfusion to the kidneys may be decreased, which may result in reduced renalfunction.c.First-pass elimination is increased because of higher portal circulation.d.First-pass elimination is reduced because of the immaturity of the liver.e.Total body water content is much less than in adults.f.Gastric emptying is slowed because of slow or irregular peristalsis.g.Gastric emptying is more rapid because of increased peristaltic activity.ANS:A, B, D, FIn children, microsomal enzymes are decreased and first-pass elimination by the liver is reduced because of the immaturity of theliver. In addition, gastric emptying is reduced because of slow or irregular peristalsis.

1Chapter 06: Medication Errors: Preventing and RespondingSealock: Lilley’s Pharmacology for Canadian Health Care Practice, 4th EditionMULTIPLE CHOICE1.Which situation is an example of a medication error?a.A patient refuses her morning medications.b.A patient receives a double dose of a medication because the nurse did not cut thepill in half.c.A patient develops hives after starting an intravenous antibiotic 24 hours earlier.d.A patient reports severe pain still present 60 minutes after a pain medication wasgiven.ANS:BA medication error is defined as apreventableadverse drug event that involves inappropriate medication use by a patient or healthcare provider. Refusing morning medications and reporting severe pain after having been given medication are examples of patientbehaviours. The development of hives is a possible allergic reaction. None of these situations is preventable.DIF:Cognitive Level: Application2.Which is the proper notation for the dose of the drug ordered?a.digoxin .125 mgb.digoxin .1250 mgc.digoxin 0.125 mgd.digoxin 0.1250 mgANS:CAlways use a leading zero for decimal dosages (e.g., digoxin 0.125 mg) with medication orders or their transcription. Omitting theleading zero may cause the order to be misread, resulting in a large drug overdose. Never use trailing zeros.DIF:Cognitive Level: Application3.When the nurse is giving a scheduled morning medication, the patient states, “I haven’t seen that pill before. Are you sure it’scorrect?” The nurse checks the medication administration record and sees that medication is listed. Which is the nurse’s bestresponse to the patient?a.“It’s listed here on the medication sheet, so you should take it.”b.“Go ahead and take it, and then I’ll check with your doctor about it.”c.“It wouldn’t be listed here if it wasn’t ordered for you!”d.“I’ll check on the order first, before you take it.”ANS:DWhen giving medications, the nurse must always listen to and honour any concerns or doubts expressed by the patient. If thepatient doubts an order, the nurse should check the written order, check with the prescriber, or both. The other options includedwith this example illustrate the nurse’s not listening to the patient’s concerns.DIF:Cognitive Level: Application4.The physician has written admission orders, and the nurse is transcribing them. The nurse is having difficulty transcribing one orderbecause of the physician’s handwriting. The best action for the nurse to take is toa.ask a colleague what the order says.b.contact the physician to clarify the order.c.contact the pharmacy to clarify the order.d.ask the patient what medications are being taken at home.ANS:BIf a prescriber writes an order that is illegible, the nurse should contact the prescriber for clarification. The nurse should not ask acolleague what the order says because the colleague did not write the order. The nurse should not contact the pharmacy to clarifythe order because this action would delay implementation of the order. Asking the patient what medications are taken at home isincorrect because this question will not clarify the current order.DIF:Cognitive Level: Comprehension5.Health care providers should report actual and potential medication errors to which organization?a.Institute for Safe Medications Practices (ISMP) Canadab.Accreditation Canadac.Canadian Patient Safety Institute (CPSI)d.Health CanadaANS:AActual and potential medication errors should be reported to ISMP Canada; confidentiality of the reporter is respected.Accreditation Canada, CPSI, and Health Canada all offer information pertaining to medication safety.DIF:Cognitive Level: KnowledgelOMoARcPSD|13778330

1Chapter 07: Patient Education and Drug TherapySealock: Lilley’s Pharmacology for Canadian Health Care Practice, 4th EditionMULTIPLE CHOICE1.Which diagnosis is appropriate for the patient who has just received a prescription for a new medication?a.Nonadherence related to a new drug therapyb.High risk for nonadherence related to new drug therapyc.Knowledge deficit related to newly prescribed drug therapyd.Deficient knowledge related to newly prescribed drug therapyANS:DThe patient who has a limited understanding of newly prescribed drug therapy may have the nursing diagnosis of deficientknowledge. “Nonadherence” implies that the patient does not follow a recommended regimen, which is not the case with a newlyprescribed drug. “High risk for nonadherence related to new drug therapy” is not a North American Nursing Diagnosis Associationnursing diagnosis, and “Deficient knowledge related to newly prescribed drug therapy” is an outdated nursing diagnosis.DIF:Cognitive Level: Analysis2.Which statement reflects a measurable goal?a.The patient will know about insulin injections.b.The patient will understand the principles of insulin preparation.c.The patient will demonstrate the proper technique of mixing insulin.d.The patient will comprehend the proper technique of preparing insulin.ANS:CThe word “demonstrate” is a measurable verb, and measurable terms should be used when developing goals and outcome criteriastatements. The terms “know,” “understand” and “comprehend”are not measurable terms.DIF:Cognitive Level: Analysis3.During an assessment, which question allows the nurse to clarify and open up discussion with the patient?a.“Are you allergic to penicillin?”b.“What medications do you take?”c.“Have you had a reaction to this drug?”d.“Are you taking this medication with meals?”ANS:B“What medications do you take?” is an open-ended question that will encourage more clarification and discussion from the patient.“Are you allergic to penicillin?” is a closed-ended question, as are “Have you had a reaction to this drug?” and “Are you taking thismedication with meals?” Closed-ended questions prompt only a “yes” or “no” answer and provide limited information.DIF:Cognitive Level: Application4.The nurse is setting up a teaching–learning session with an 85-year-old patient who will be going home on anticoagulant therapy.Which strategy will reflect consideration of aging changes that may occur?a.Showing a colourful video about anticoagulation therapyb.Presenting all the information in one session just before dischargec.Giving the patient pamphlets about the medications to read at homed.Developing large-print handouts that reflect the verbal information presentedANS:DDeveloping large-print handouts that reflect the verbal information presented will address altered perception in two ways. First,using visual aids reinforces the verbal instructions by addressing the patient’s possibly decreased ability to hear high-frequencysounds. Second, developing the handouts in large print addresses the possibility of decreased visual acuity. Showing a colourfulvideo about anticoagulation therapy does not allow for discussion of the information; furthermore, the text and print may be smalland difficult to read and understand. Presenting all the information in one session just before discharge also does not allow fordiscussion, and the patient may not be able to hear or see the information sufficiently. Because of the possibility of decreasedshort-term memory and slowed cognitive function, giving the patient pamphlets about the medications to read at home is notappropriate.DIF:Cognitive Level: Application5.When the nurse is teaching a manual skill, such as self-injection of insulin, the best way to set up the teaching-learning session is toa.provide written pamphlets for instruction.b.show a video and allow the patients to practice as needed on their own.c.verbally explain the procedure and provide written handouts for reinforcement.d.allow the patients to do several “return” demonstrations after the nurse hasdemonstrated the procedure.ANS:DReturn demonstrations allow the nurse to evaluate the patient’s newly learned skills. Providing written pamphlets for instruction,showing a video and then allowing patients to practice as needed on their own, and verbally explaining the procedure and providingwritten handouts for reinforcement do not allow for evaluation of the patient’s technique.DIF:Cognitive Level: AnalysislOMoARcPSD|13778330

This reviewingconstitutes learning in which domain?a.Physicalb.Affectivec.Cognitived.PsychomotorANS:CThe cognitive domain refers to problem-solving abilities and may involve recall and knowledge of facts. The physical domain isnot one of the learning domains. The affective domain refers to values and beliefs. The psychomotor domain may involve actionssuch as learning how to perform a procedure.DIF:Cognitive Level: Comprehension7.The nurse needs to teach a 16-year-old patient, newly diagnosed with diabetes, about blood glucose monitoring and the importanceof regulating glucose intake. When the nurse is developing the teaching plan, which of Erickson’s stages of development should beconsidered?a.Trust versus mistrustb.Intimacy versus isolationc.Industry versus inferiorityd.Identity versus role confusionANS:DAccording to Erickson, the adolescent, 12 to 18 years of age, is in the “identity versus role confusion” stage of development.According to Erikson, “trust versus mistrust” reflects the infancy stage; “intimacy versus isolation” reflects the young adulthoodstage; and “industry versus inferiority” reflects the school-age stage of development.DIF:Cognitive Level: Comprehension8.A 60-year-old patient is on several new medications and expresses worry that she will forget to take her pills. For a patient in thissituation, the most helpful response from the nurse is to do what?a.Teach effective coping strategies.b.Reduce the number of drugs prescribed.c.Assure the patient that she won’t forget once she is accustomed to the routine.d.Help the patient obtain and learn to use a calendar or a pill container.ANS:DCalendars, pill containers, or diaries may be helpful to patients who may forget to take prescribed drugs as scheduled. The nursemust ensure that the patient knows how to use these reminder tools. Teaching the patient effective coping strategies is a helpfulsuggestion but will not help the patient to remember to take medications. Reducing the number of drugs prescribed is not anappropriate action by the nurse. Assuring the patient that she won’t forget once she is accustomed to the routine is false reassuranceby the nurse and inappropriate when education is needed.DIF:Cognitive Level: ApplicationMULTIPLE RESPONSE1.Which are appropriate considerations when the nurse is assessing the learning needs of a patient?

Kava is promoted for the treatment ofanxiety, nervousness, insomnia, pain, and muscle tension. Health Canada has issued warnings about possible liver toxicity with theuse of kava root. In 2012, after a 10-year ban, Health Canada regulated kava root as a new drug.DIF:Cognitive Level: Knowledge4.A patient tells the nurse that she wants to begin taking St. John’s wort for treatment of depression. The nurse should warn her aboutwhich substance that may cause an interaction with St. John’s wort?a.digoxinb.All caffeine-containing productsc.Alcoholic beveragesd.Selective serotonin reuptake inhibitorsANS:DDrug interactions may occur with the ingestion of other serotonergic drugs, such as selective serotonin reuptake inhibitors; the druginteraction may lead to serotonin syndrome.DIF:Cognitive Level: Comprehension5.A patient says that he eats large amounts of garlic for its cardiovascular benefits. Which drug, if taken, could have a potentialinteraction with the garlic?a.acetaminophenb.warfarinc.digoxind.phenytoinANS:BWhen taking garlic, taking any drugs that may interfere with platelet and clotting functions should be avoided. These drugs includeantiplatelet drugs, anticoagulants (e.g., warfarin), nonsteroidal anti-inflammatory drugs (NSAIDs), and acetylsalicylic acid(Aspirin).

26.When teaching patients about over-the-counter (OTC) and natural health products, the nurse should teach the patients thata.histamine-blocking agents should be taken with antacids to preventgastrointestinal upset.b.drug interactions are rare with OTC products because OTC drugs are safer thanprescription drugs.c.manufacturers of natural health products are required to provide evidence ofsafety and effectiveness; therefore, check the labels carefully.d.natural health products and OTC drugs cannot be safely administered to infants,children, and pregnant or lactating women without first checking with the healthcare provider.ANS:DNatural health products and OTC drugs are not necessarily safe for infants, children, and pregnant or lactating women; the healthcare provider should be contacted before use. “Histamine-blocking agents should be taken with antacids to prevent gastrointestinalupset,” “Drug interactions are rare with OTC products because OTC drugs are safer than prescription drugs,” and “Manufacturersof natural health products are required to provide evidence of safety and effectiveness; therefore, check the labels carefully” are allfalse statements.DIF:Cognitive Level: Comprehension7.Patients from which culture will not report gastrointestinal symptoms caused by OTC drugs or natural health products?a.Chineseb.Japanesec.Hispanicd.EuropeanANS:BJapanese patients experiencing nausea, vomiting, or bowel changes as a result of OTC drugs or natural health products often do notmention these symptoms. Because the Japanese culture considers complaining about gastrointestinal symptoms to be unacceptable,these symptoms may go unreported. The nurse needs to be aware of this implication for this ethnocultural group.DIF:Cognitive Level: ComprehensionMULTIPLE RESPONSE1.Which statement is true regarding the use of OTC drugs? (Select all that apply.)a.Use of OTC drugs may delay treatment of more serious ailments.b.Drug interactions with OTC medications are rare.c.OTC drugs may relieve symptoms without addressing the cause of the problem.d.OTC drugs are indicated for long-term treatment of conditions.e.Patients may misunderstand product labels and misuse the drugs.ANS:A, C, E“Use of OTC drugs may delay treatment of more serious ailments,” “OTC drugs may relieve symptoms without addressing thecause of the problem,” and “Patients may misunderstand product labels and misuse the drugs” are all true statements about the useof OTC drugs and should be included when patients are being taught about their use.

It is believed to originate from vascular orperivascular tissues. It is characterized by persistent and recurring pain lasting 3 to 6 months. Acute pain is sudden and usuallysubsides when treated. Phantom pain occurs in the area of a body part that has been removed—surgically or traumatically—and isoften described as burning, itching, tingling, or stabbing. It can also occur in paralyzed limbs following spinal cord injury.DIF:Cognitive Level: Comprehension2.An 18-year-old basketball player fell and twisted his ankle during a game. Which type of analgesic is he likely to be given?a.A synthetic opioid, such as meperidine hydrochlorideb.An opium alkaloid, such as morphine sulphatec.An opioid antagonist, such as naloxone hydrochloride (Suboxone®)d.A non-opioid analgesic, such as tramadolANS:DPain originating from skeletal muscles, ligaments, and joints usually responds to non-opioid analgesics such as nonsteroidalanti-inflammatory drugs (NSAIDs). All drugs in the NSAID class are especially useful for pain associated with inflammatoryconditions because these drugs have analgesic and anti-inflammatory effects.DIF:Cognitive Level: Application3.A patient is in the recovery room following abdominal surgery. He is groggy but reports severe pain around his incision. What isthe most important factor for the nurse to consider during her patient assessment before administering a dose of morphine sulphate?a.Temperatureb.Respiration ratec.Appearance of the incisiond.Time of last bowel movementANS:BOne of the most serious side effects of opioids is respiratory depression, so respiration must be assessed prior to administering adose of morphine.DIF:Cognitive Level: Analysis4.A 78-year-old patient is in the recovery room after lengthy hip surgery. While gradually awakening, the patient requests painmedication. Within 10 minutes after receiving a dose of morphine sulphate, the patient is very lethargic; respiration is shallow, at arate of nine respirations per minute. What necessary action may the nurse need to perform?a.Close observation for signs of opioid toleranceb.Immediate intubation and artificial ventilationc.Administration of naloxone, an opioid reversal agentd.Administration of an agonist opioid, such as fentanyl (Duragesic Mat)ANS:CNaloxone, an opioid reversal agent, is used to reverse the effects of acute opioid overdose and is the drug of choice for reversal ofopioid-induced respiratory depression.DIF:Cognitive Level: Application5.A patient will be discharged with a 1-week supply of an opioid analgesic for pain management after his abdominal surgery. Whatshould the nurse teach this patient in regard to this drug?a.How to manage diarrheab.How to access drug addiction programsc.How to prevent constipationd.How to avoid dehydration due to polyuriaANS:CGastrointestinal occurrences such as nausea, vomiting, and constipation are the most common adverse effects associated withopioid analgesics.

What is this patientexperiencing?a.Opioid toxicityb.Addictionc.Opioid toleranced.Abstinence syndromeANS:COpioid tolerance is a common physiological result of long-term opioid use. Patients with opioid tolerance require larger doses ofthe opioid agent to maintain the same level of analgesia.DIF:Cognitive Level: Comprehension7.A 38-year-old male has arrived at the urgent care centre with severe hip pain after falling from a ladder at work. He has takenseveral pain pills over the past few hours but cannot remember how many he has taken. He hands the nurse an empty bottle ofacetaminophen (Tylenol®). What is the most serious toxic effect of acute acetaminophen overdose?a.Tachycardiab.Central nervous system (CNS) depressionc.Hepatic necrosisd.Nephrotic necrosisANS:CHepatic necrosis is the most serious acute toxic effect of an acute overdose of acetaminophen. Tachycardia and CNS depression arenot side effects of acute acetaminophen overdose. Long-term, not short-term, ingestion of large doses is more likely to result innephropathy.DIF:Cognitive Level: Comprehension8.The drug pentazocine (Talwin®) is a narcotic agonist–antagonist. Which statement describes a characteristic of this type ofmedication?a.It has minimal analgesic effects.b.It works to reverse the effects of opiates.c.Its adverse effects differ from those of the opiate narcotics.d.It has a lower addiction potential than opiate narcotics.ANS:DOpioid agonist–antagonist drugs generally have lower addiction potentials than opiate narcotics.DIF:Cognitive Level: Comprehension9.A 57-year-old patient has been on a transdermal narcotic analgesic as part of the management of pain for end-stage breast cancer.Lately, she has experienced “breakthrough” pain. How should this pain be addressed?a.She should be given NSAIDs.b.Her current therapy should not be changed.c.The baseline dose of the narcotic may need to be increased in increments.d.The narcotic route should be changed to the rectal route, to increase absorption.ANS:CIf a patient is requiring larger doses for breakthrough pain, the baseline dose of the narcotic may need to be titrated upward.DIF:Cognitive Level: Analysis10.For which situation is the herb feverfew commonly used?a.Muscle achesb.Headachesc.Leg crampsd.Incisional pain after surgeryANS:BFeverfew is commonly used to treat migraine headaches, menstrual problems, arthritis, and fever. Possible adverse effects includemuscle stiffness and muscle and joint pain.DIF:Cognitive Level: Comprehension11.A patient is to receive acetylcysteine as part of treatment for an acetaminophen overdose. Which action by the nurse is appropriatewhen administering this medication?a.Giving the medication undiluted for full effectb.Avoiding the use of a straw when giving the medicationc.Disguising the flavour with a soft drink or flavoured waterd.Preparing to give the medication via a nebulizerANS:CAcetylcysteine has the flavour of rotten eggs. It is better tolerated when the taste is disguised by mixing it with a soft drink orflavoured water to increase its palatability. Giving this medication undiluted is not recommended. The use of a straw will helpminimize contact with mucous membranes of the mouth and is recommended. The nebulizer form of this medication is used forcertain types of pneumonia, not acetaminophen overdose.DIF:Cognitive Level: ApplicationlOMoARcPSD|13778330

1Chapter 12: General and Local AnaestheticsSealock: Lilley’s Pharmacology for Canadian Health Care Practice, 4th EditionMULTIPLE CHOICE1.After piercing a finger with a fish hook during a fishing trip, a patient is now at an emergency department to have the hookremoved. What type of anaesthesia will be used for this procedure?a.Topical benzocaine spray to the areab.Spinal anaesthesia with mepivacaine hydrochloridec.Topical prilocaine cream (EMLA®) around the sited.Infiltration of the area with tetracaine hydrochlorideANS:DInfiltration anaesthesia is commonly used for minor surgical procedures. It involves injecting the local anaesthetic solutionintradermally, subcutaneously, or submucosally across the path of nerves supplying the area to be anaesthetized. The localanaesthetic may be administered in a circular pattern around the operative field.DIF:Cognitive Level: Application2.A patient is to receive local anaesthesia for removal of a lymph node from the groin. Why does the physician add epinephrine to thelocal anaesthetic during the preparation?a.Epinephrine prevents an anaphylactic reaction from occurring.b.The anaesthetic enhances the effect of the epinephrine.c.Epinephrine contributes to a balanced anaesthetic state.d.Vasoconstrictive effects keep the anaesthetic at its local site of action.ANS:DVasoconstrictors such as epinephrine are coadministered with local anaesthetics to keep the anaesthetic at its local sit e of actionand to prevent systemic absorption.DIF:Cognitive Level: Application3.During the postoperative recovery period, what should be the nurse’s immediate main concern?a.Pupil responsesb.Return to sensationc.Level of consciousnessd.Airway, breathing, and circulationANS:DAfter surgery and the termination of general anaesthesia, the nurse’s main concern should be assessing the patient’s airway,breathing, and circulation status.DIF:Cognitive Level: Application4.While monitoring a patient who had surgery under general anaesthesia 2 hours earlier, the nurse notes a sudden elevation in bodytemperature. What does this sudden elevation in body temperature indicate?a.Tachyphylaxisb.Postoperative infectionc.Malignant hypothermiad.Malignant hyperthermiaANS:DA sudden elevation in body temperature during the postoperative period may indicate the occurrence of malignant hyperthermia, alife-threatening emergency.DIF:Cognitive Level: Application5.Which individual is at high risk for an altered response to anaesthesia?a.A 30-year-old male who has never had surgery beforeb.A 45-year-old female who stopped smoking 10 years agoc.A 20-year-old male who is to have a lymph node removedd.A 78-year-old female who is to have her gallbladder removedANS:DThe older adult patient is more affected by anaesthesia because of the effects of aging on the hepatic, cardiac, respiratory, and renalsystems. Young or middle-aged adult patients are not at high risk for an altered response to anaesthesia.DIF:Cognitive Level: AnalysislOMoARcPSD|13778330

26.A patient is undergoing abdominal surgery and has been anaesthetized for 3 hours. Which nursing diagnosis is appropriate for him?a.Anxiety related to the use of an anaestheticb.Risk for injury related to increased sensorium from general anaesthesiac.Decreased cardiac output related to systemic effects of local anaesthesiad.Impaired gas exchange related to central nervous system (CNS) depressionproduced by general anaesthesiaANS:DImpaired gas exchange related to CNS depression produced by general anaesthesia is the appropriate nursing diagnosis for thispatient. Because the patient is under anaesthesia, the nurse is unable to assess the patient for anxiety. Risk for injury is related todecreased sensorium, not increased sensorium from general anaesthesia. “Decreased cardiac output related to systemic effects oflocal anaesthesia” is incorrect because local anaesthesia should have very little systemic effect.DIF:Cognitive Level: Application7.When administering a neuromuscular drug such as pancuronium, what does the nurse need to remember?a.It can be used instead of general anaesthesia during surgery.b.Only skeletal muscles are paralyzed; respiratory muscles remain functional.c.It causes sedation and pain relief while allowing for lower doses of anaesthetics.d.Patients will require artificial mechanical ventilation because of paralyzedrespiratory muscles.ANS:DPatients receiving neuromuscular blocking agents (NMBAs) will require artificial mechanical ventilation because of the resultantparalysis of the respiratory muscles. NMBAs do not cause sedation or pain relief and cannot be used in place of general anaesthesiaduring surgery. Respiratory muscles are paralyzed by this drug.DIF:Cognitive Level: Application8.A patient has been given succinylcholine (Quelicin®) after a severe injury that necessitated controlled ventilation. The physiciannow wants to reverse the paralysis. The nurse would expect to use which drug to reverse the succinylcholine?a.diazepam (Valium®)b.caffeinec.neostigmine methylsulphated.vecuronium bromide (Norcuron®)ANS:CThe antidote for NMBAs such as succinylcholine is neostigmine methylsulphate. It reverses the effects of the NMBAs.DIF:Cognitive Level: Application9.A patient is being prepared for an oral endoscopy, and the nurse reminds him that he will be awake during the procedure butprobably will not remember it. What type of anaesthetic technique is used in this situation?a.Twilight sleepb.Procedural sedationc.Adjunctive anaesthesiad.Spinal anaesthesiaANS:BProcedural sedation effectively reduces patient anxiety, sensitivity to pain, and recall of the medical procedure, yet it preserves thepatient’s ability to maintain his or her own airway and to respond to verbal commands.DIF:Cognitive Level: Comprehension10.Which symptom may occur if a patient is taking ginger and requires an anaesthetic?a.Decreased blood pressureb.Increased risk of bleedingc.Increased risk of stroked.Migraine headachesANS:BA patient who has been taking the natural health product ginger and requires anaesthesia is at an increased risk of bleeding,especially if acetylsalicylic acid (Aspirin) or ginkgo is also being taken. Decreased blood pressure, increased risk of stroke, andmigraine headaches are risks associated with the combination of anaesthesia with some natural health products, but not with ginger.DIF:Cognitive Level: ComprehensionOTHER1.When a neuromuscular blocking drug is given, the effects occur in a certain order. Put the following drug effects in the properorder of occurrence, using the choices A through C listed below.a. Cessation of respirations due to paralysis of diaphragm and intercostal musclesb. Total flaccid paralysisc. WeaknessANS:C, B, AThe first sensation typically experienced is muscle weakness. This is usually followed by a total flaccid paralysis. Small, rapidlymoving muscles such as those of the fingers and eyes are typically the first to be paralyzed. The next are those of the limbs, neck,and trunk. Finally, the intercostal muscles and the diaphragm are paralyzed. The patient can no longer breathe independently.DIF:Cognitive Level: ApplicationlOMoARcPSD|13778330

1Chapter 13: Central Nervous System Depressants and Muscle RelaxantsSealock: Lilley’s Pharmacology for Canadian Health Care Practice, 4th EditionMULTIPLE CHOICE1.Which is a true statement about sedatives and hypnotics?a.The two terms mean the same thing.b.A hypnotic causes sleep.c.Low doses of sedatives will cause sleep.d.Compared with sedatives, hypnotics have a less potent effect on the centralnervous system.ANS:BA sedative reduces nervousness, excitability, and irritability without causing sleep, whereas a hypnotic causes sleep.DIF:Cognitive Level: Knowledge2.A patient who has been taking phenobarbital for 2 weeks as part of therapy for epilepsy reports feeling tense and that the “leastlittle thing” is a bother now. What is the nurse’s best explanation to the patient?a.These adverse effects will often subside after a few weeks.b.The drug should be stopped immediately because of possible adverse effects.c.This drug causes the rapid eye movement (REM) sleep period to increase,resulting in nightmares and restlessness.d.This drug causes deprivation of REM sleep and may cause the patient’s inabilityto deal with normal stress.ANS:DBarbiturates deprive people of REM sleep, which can result in agitation and an inability to deal with normal stress. A reboundphenomenon occurs when the drug is stopped, and the proportion of REM sleep increases, sometimes resulting in nightmares.DIF:Cognitive Level: Application3.A 50-year-old male who has been taking a benzodiazepine for 1 week is found unresponsive. His wife states that he takes no otherprescription drugs and that he did not take an overdose—the correct number of pills is in the bottle. What might have happened?a.He took a multivitamin.b.He drank a glass of wine.c.He took a dose of Aspirin.d.He developed an allergy to the drug.ANS:BPotential drug interactions with the benzodiazepines are significant because of their intensity, particularly when they involve othercentral nervous system (CNS) depressants (e.g., alcohol, opioids, muscle relaxants).DIF:Cognitive Level: Analysis4.A patient has been taking temazepam (Restoril®) for intermittent insomnia. She tells the nurse that when she takes it, she sleepswell, but the next day she feels “so tired.” What is the nurse’s best explanation to the patient?a.Long-term use results in a sedative effect.b.She should take the drug every night to reduce this hangover effect.c.Benzodiazepines affect the sleep cycle, thus causing a hangover effect.d.Benzodiazepines increase CNS activity, thus causing tiredness the next day.ANS:CBenzodiazepines suppress rapid eye movement REM sleep to a degree (though not as much as barbiturates) and thus result in ahangover effect.DIF:Cognitive Level: Application5.A patient who is recovering from a minor automobile accident that occurred 1 week ago is taking cyclobenzaprine(Novo-Cycloprine®) for muscular pain and goes to physical therapy three times a week. Which nursing diagnosis would beappropriate for him?a.Risk for falls related to decreased sensoriumb.Risk for addiction related to psychological dependencyc.Excess fluid volume related to potential adverse effectsd.Disturbed sleep pattern related to the drug’s interference with REM sleepANS:AMusculoskeletal relaxants have a depressant effect on the CNS; lightheadedness, dizziness, drowsiness, and fatigue can occur, thusputting the patient at risk for falls. The patient should be taught the importance of taking measures to minimize self-injury and fallsrelated to decreased sensorium.DIF:Cognitive Level: AnalysislOMoARcPSD|13778330

What measures are appropriate for this patient?a.Trying to establish set sleep patternsb.Exercising before bedtime to become tiredc.Consuming heavy meals in the evening to promote sleepinessd.Drinking warm beverages, such as tea or coffee, just before bedtimeANS:ANonpharmacological approaches to induce sleep include establishing set sleep patterns. The patient should avoid heavy exercisebefore bedtime, avoid heavy meals late in the evening, and should drink warm decaffeinated drinks, such as warm milk, beforebedtime.DIF:Cognitive Level: Application7.Which is the best treatment of an acute overdose of diazepam?a.Infusion with diluted bicarbonate solutionb.Administration of medications to decrease blood pressurec.Administration of flumazenild.Administration of nalbuphine as an antagonistANS:CFlumazenil, a benzodiazepine antidote, can be used to acutely reverse the sedative effects of benzodiazepines. Flumazenilantagonizes the action of benzodiazepines on the CNS by directly competing with them for binding at the receptors. Flumazenil isused in cases of oral overdose or excessive intravenous sedation. Infusion with diluted bicarbonate solution and the administrationof medications to decrease blood pressure are not appropriate treatments. There are no antagonists for barbiturates.DIF:Cognitive Level: Analysis8.A 45-year-old female has been taking dantrolene as part of the treatment for multiple sclerosis. Which laboratory value should thenurse monitor while the patient receives dantrolene?a.Creatinineb.Sedimentation ratec.Liver function studiesd.Hemoglobin and hematocritANS:CDantrolene can cause liver damage; therefore, liver function studies should be performed during therapy.DIF:Cognitive Level: Comprehension9.What is an adverse effect of barbiturate administration?a.Vasoconstrictionb.Thrombocytopeniac.Hypertensiond.ExcitementANS:BAn adverse effect of barbiturate use is thrombocytopenia.
