What is the nurse’s priorityaction?a.Notify physician of allergic reaction.b.Notify physician of idiosyncratic reaction.c.Notify physician of potential teratogenicity.d.Notify physician of potential tolerance.ANS:AAn allergic reaction is indicative of hypersensitivity and manifests with hives and/or urticaria,which are easily identified. An idiosyncratic reaction occurs when something unusual orabnormal happens when a drug is first administered. A teratogenic reaction refers to theoccurrence of birth defects related to administration of the drug. Tolerance refers to the body’srequirement for increasing dosages to achieve the same effects that a lower dose once did.DIF:Cognitive Level: ApplicationREF:Page 17OBJ:4TOP:Nursing Process Step: AssessmentMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Clinical Judgment; Safety2.The nurse administers an initial dose of a steroid to a patient with asthma. Thirty minutes afteradministration, the nurse finds the patient agitated and stating that “everyone is out to get me.”What is the term for this unusual reaction?a.Desired actionb.Adverse effectc.Idiosyncratic reactiond.Allergic reactionANS:CIdiosyncratic reactions are unusual, abnormal reactions that occur when a drug is firstadministered. Patients typically exhibit an overresponsiveness to a medication related todiminished metabolism. These reactions are believed to be related to genetic enzymedeficiencies. Desired actions are expected responses to a medication. Adverse effects arereactions that occur in another system of the body; they are usually predictable. Allergicreactions appear after repeated medication dosages.DIF:Cognitive Level: KnowledgeREF:Page 18OBJ:4TOP:Nursing Process Step: EvaluationMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Patient Education; Clinical Judgment; Caregiving; Safety; Sensory Perception3.Which is the best description of when drug interactions occur?a.On administration of toxic dosages of a drugb.On an increase in the pharmacodynamics of bound drugsc.On the alteration of the effect of one drug by another drugd.On increase of drug excretion
Page 9 of 16
Basic Pharmacology for Nurses 17th Edition Test Bank - Page 9 preview imageANS:CDrug interactions may be characterized by an increase or decrease in the effectiveness of oneor both of the drugs. Toxicity of one drug may or may not affect the metabolism of anotherone. Drug interactions may result from either increased or decreased pharmacodynamics.Drug interactions may result from either increased or decreased excretion.DIF:Cognitive Level: ComprehensionREF:Page 18OBJ:5TOP:Nursing Process Step: AssessmentMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Safety; Patient Education; Clinical Judgment4.What occurs when two drugs compete for the same receptor site, resulting in increasedactivity of the first drug?a.Desired actionb.Synergistic effectc.Carcinogenicityd.DisplacementANS:DThe displacement of the first drug from receptor sites by a second drug increases the amountof the first drug because more unbound drug is available. An expected response of a drug isthe desired action. A synergistic effect is the effect of two drugs being greater than the effectof each chemical individually or the sum of the individual effects. Carcinogenicity is theability of a drug to cause cells to mutate and become cancerous.DIF:Cognitive Level: ComprehensionREF:Page 19OBJ:6TOP:Nursing Process Step: ImplementationMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Safety; Patient Education5.What do drug blood levels indicate?a.They confirm if the patient is taking a generic form of a drug.b.They determine if the patient has sufficient body fat to metabolize the drug.c.They verify if the patient is taking someone else’s medications.d.They determine if the amount of drug in the body is in a therapeutic range.ANS:DThe amount of drug present may vary over time and the blood level must remain in atherapeutic range in order to obtain the desired result. Generic drugs do not necessarilyproduce a different drug blood level than proprietary medications. Body fat is not measuredby drug blood levels. Drug blood levels only measure the amount of drug in the body; they donot determine the source of the medication.DIF:Cognitive Level: ComprehensionREF:Page 17OBJ:4TOP:Nursing Process Step: EvaluationMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Clinical Judgment; Safety6.What is the process by which a drug is transported by circulating body fluids to receptor sites?a.Osmosisb.Distributionc.Absorption
Page 10 of 16
Basic Pharmacology for Nurses 17th Edition Test Bank - Page 10 preview imaged.BiotransformationANS:BDistribution refers to the ways in which drugs are transported by the circulating body fluids tothe sites of action (receptors), metabolism, and excretion. Osmosis is the process of movingsolution across a semipermeable membrane to equalize the dilution on each side. Absorptionis the process by which a drug is transferred from its site of entry into the body to thecirculating fluids for distribution. Biotransformation, also called metabolism, is the process bywhich the body inactivates drugs.DIF:Cognitive Level: ComprehensionREF:Page 15OBJ:3TOP:Nursing Process Step: PlanningMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Patient Education; Clinical Judgment; Safety7.The nurse assesses which blood level to determine the amount of circulating medication in apatient?a.Peakb.Troughc.Drugd.TherapeuticANS:CWhen a drug is circulating in the blood, a blood sample may be drawn and assayed todetermine the amount of drug present; this is known as the drug blood level. Peak levels areonly those drug blood levels that are at their maximum before metabolism starts to decreasethe amount of circulating drug. Trough levels are only those drug blood levels that are at theirminimum when metabolism has decreased the amount of circulating drug and before anincrease caused by a subsequent dose of the medication. Therapeutic levels are only thosewithin a prescribed range of blood levels determined to bring about effective action of themedication.DIF:Cognitive Level: ComprehensionREF:Page 17OBJ:3TOP:Nursing Process Step: EvaluationMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Patient Education; Clinical Judgment; Safety8.The nurse administers 50 mg of a drug at 6:00 AM that has a half-life of 8 hours.

In order to mix twodrugs, compatibility is determined so there is no deterioration when the drugs are mixed in thesame syringe. Drug level does not indicate if it is acceptable to mix medications in the samesyringe. Adverse effects are important for the nurse to know, but not in order to mix drugs.DIF:Cognitive Level: ApplicationREF:Page 19OBJ:6TOP:Nursing Process Step: ImplementationMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Clinical Judgment; Safety10.A patient developed hives and itching after receiving a drug for the first time. Whichinstruction by the nurse is accurate?a.Stop the medication and encourage the patient to wear a medical alert bracelet thatexplains the allergy.b.Explain to the patient that these are signs and symptoms of an anaphylacticreaction.c.Emphasize to the patient the importance to inform medical personnel that in thefuture a lower dosage of this drug is necessary.d.Instruct the patient that it would be safe to take the drug again because thisinstance was a mild reaction.ANS:AThis initial allergic reaction is mild, and the patient is more likely to have an anaphylacticreaction at the next exposure; a medical alert bracelet is necessary to explain the reaction.Signs and symptoms of an anaphylactic reaction are respiratory distress and cardiovascularcollapse. A more severe reaction will occur at the next exposure, and the patient should notreceive the drug again.DIF:Cognitive Level: ApplicationREF:Page 18OBJ:4TOP:Nursing Process Step: ImplementationMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Patient Education; Clinical Judgment; Safety11.When obtaining a patient’s health history, which assessment data would the nurse identify ashaving the most effect on drug metabolism?a.History of liver diseaseb.Intake of a vegetarian dietc.Sedentary lifestyled.Teacher as an occupationANS:A

The nurse can anticipate that the patient will receive this medicationa.intramuscularly.b.subcutaneously.c.topically.d.rectally.ANS:CThe percutaneous route refers to drugs that are absorbed through the skin and mucousmembranes. Methods of the percutaneous route include inhalation, sublingual (under thetongue), or topical (on the skin) administration. The parenteral route bypasses thegastrointestinal (GI) tract by using subcutaneous (subcut), intramuscular (IM), or intravenous(IV) injection. The parenteral route bypasses the GI tract by using subcut, IM, or IV injection.In the enteral route, the drug is administered directly into the GI tract by the oral, rectal, ornasogastric route.DIF:Cognitive Level: ApplicationREF:Page 14OBJ:1TOP:Nursing Process Step: ImplementationMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Patient Education; Clinical Judgment; Safety13.A nurse is preparing to administer tetracycline to a patient diagnosed with an infection.

Before a solid drug taken orally can be absorbed into thebloodstream for transport to the site of action, it must disintegrate and dissolve in the GI fluidsand be transported across the stomach or intestinal lining into the blood. The process ofconverting a drug into a soluble form can be partially controlled by the pharmaceutical dosageform used (e.g., solution, suspension, capsules, and tablets with various coatings). Theconversion process can also be influenced by administering the drug with or without food inthe patient’s stomach. Elixirs are already drugs dissolved in a liquid and do not need to beliberated from the dosage form.DIF:Cognitive Level: ComprehensionREF:Page 14OBJ:3TOP:Nursing Process Step: ImplementationMSC:NCLEX Client Needs Category: Physiological IntegrityNOT:CONCEPT(S): Patient Education; Clinical Judgment; Safety2.Which are routes of drug excretion?
