ANS: A A study that assesses the effectiveness of int erventions helps to improve the health of patient populations by identifying appropriate strategies. A comparison of attitudes is a descriptive study that does not improve outcomes. A study to generate nursing diagnoses does not directly affect patient out comes. A study reviewing adherence to guidelines seeks to provide data for quality assurance. DIF: Cognitive level: Applying (Application) 15. Which best describes the Quality and Safety Education for Nurses (QSEN) competency for evidence - based practi ce (EBP)? a. Adhering to published guidelines to provide care for a specific population b. Empowering clients to choose among effective disease management strategies c. Relying on expert knowledge to guide care plan development for an individual patient d. Using evidence gained solely from experimental studies to guide care ANS: B The QSEN competency for EBP is defined as integrating the best evidence with clinical expertise and patient/family preferences. Strict adherence to guidelines does not take t he patient/family preferences into account. EBP does not rely solely on expert knowledge or experimental studies. Although experimental studies provide the highest level of study data, EBP does not rely solely on experimental studies. DIF: Cognitive le vel: Applying (Application)

Do children who have an updated asthma actio n plan have fewer missed school days caused by asthma? c. Which asthma triggers influence poor attitudes about chronic disease? d. Which bronchodilator medication has fewer side effects? ANS: B, D Determining which interventions reduce asthma sick days is a controlled, quantitative, experimental study design; and a study about the effects of a medication is an experimental study. Asking what it is like to live with asthma will generate qualitative d ata. A study determining relationships between asthma triggers and attitudes about disease is a correlational study. DIF: Cognitive level: Analyzing (Analysis) Chapter 02: Introduction to Quantitative Research Grove: Understanding Nursing Research, 8 th Edition MULTIPLE CHOICE 1. A researcher conducts a study which outlines the daily habits of women who are overweight. This study represents what type of resea rch? a. Correlational b. Descriptive c. Experimental d. Quasi - experimental ANS: B Descriptive research is the exploration and description of phenomena in real - life situations. Correlational research involves the systematic investigation of relationships between or among variables. Experimental research is an objective, systematic, highly controlled investigation conducted for the purpose of predicting and contro lling phenomena. The purpose of quasi - experimental research is to examine causal relationships or determine the effect of one variable on another. Thus these studies involve implementing a treatment or

The nurse evaluates a research study that examines the relationship between computer and television screen time and obesity. A cor relational analysis reveals a correlation of +0.95. What can the nurse conclude about the relationship between these two variables? a. An increase in screen time causes obesity. b. An increase in obesity leads to increased screen time. c. Screen time and obes ity vary in opposite directions. d. Screen time and obesity vary together. ANS: D A positive correlation between variables indicates that the variables vary together. Variables that vary in opposite directions will have a negative correlation. Descriptive research is the exploration of phenomena in real - life situations. Correlational st udies do not indicate cause, so an increase in screen time or an increase in obesity does not cause or lead to an increase in the other. DIF: Cognitive level: Analyzing (Analysis) 4. The overall plan developed by the researcher to obtain answers to t he questions being studied is called

  20. Page 20

    a. analysis of data. b. operationally defining the variables. c. problem statement. d. research design. ANS: D Research design is a blueprint for the conduct of a study that maximizes control over factors that could inter fere with the study’s desired outcome. Data analysis reduces, organizes, and gives meaning to the data. Researchers develop an operational definition so that the variables can be measured or an intervention implemented in a study. The problem statement in a study usually identifies an area of concern for a particular population that requires investigations. DIF: Cognitive level: Understanding (Comprehension) 5. In which type of research does the researcher seek to examine causal relationships among variables without being able to manipulate the variables? a. Descriptive b. Correlational c. Experimental d. Quasi - experimental ANS: D Quasi - experimental studies have less control than experimental studies, but they do exhibit some degree of control. Descriptive research is the exploration of phenomena in real - life situations. Correlational research investigates the relationship between or among variables but does not attribute cause. Experimental design is considered the most powerful quantitative design because of the rigorous control of variables. DIF: Cognitive level: Understanding (Comprehension) 6.

    12. A researcher designs a study to evaluate stress and anxiety associated with breastfeeding in which data collection takes place in the homes of mothers with premature newborns after discharge home from the NIC. Thi s would be an example of which type of research setting? a. Highly controlled, field b. Highly controlled, laboratory c. Natural, field d. Partially controlled, laboratory ANS: C The setting describes where the research and data collection occur. A natural setting, or field setting, is an uncontrolled, real - life situation or environment, such as the home. In a natural setting, there is relatively little control over the setting and the variables associated with the setting. There are three common settings for conducting research: natural, partially controlled, and highly controlled. A highly controlled setting would involve experimental control of an independent variable, which this study does not do. This is a field study, with data collection occurring in patients’ homes and not in a laboratory. A natural setting, or field setting, is an uncontrolled, real - life situation or environment. This is a field study, with data collection o ccurring in patients’ homes and not in a laboratory. DIF: Cognitive level: Applying (Application) 13. When conducting a research study using a convenience sample of all second - grade students from two classrooms in a nearby school, the nurse researcher may increase the sample control by a. assigning one classroom to the experimental group and the other classroom to the control group. b. exposing all subjects to the treatment variable and then comparing the outcome data to pretreatment data. c. randomly assign ing students from both classrooms to either the experimental group or the control group. d. using these subjects as treatment subjects and comparing outcomes to a group of subjects from a similar study. ANS: C Randomly assigning subjects to either a tr eatment group or a control group improves sample control and decreases bias. Even when convenience sampling is used, subjects may be randomly assigned to groups. Assigning one classroom to one group and the other classroom to the other group is less effective than random sampling. Pre - and post - treatment comparison may be used when random assignment is not possible. Compar ing a treatment group to a

    group in another study does not control the treatment variables because of variations between two studies. DIF: Cognitive level: Analyzing (Analysis) 14. A nurse is assisting with data collection for a study measuring the ef fects of a sleep aid medication on oxygen saturations. Subjects will sleep in a darkened room in a sleep lab while participating. Which type of research setting is this? a. Field b. Highly controlled c. Natural d. Partially controlled ANS: B A highly controlled setting is one in which the influence of extraneous variables is greatly reduced. Examples of such a setting would include laboratories, research or experimental centers, and test units in hospitals. Field settings are uncontrolled, rea l - life situations or environments. Natural settings are uncontrolled, real - life situations or environments. Partially controlled settings are environments that the researcher has manipulated or modified in some way. DIF: Cognitive level: Applying (Application) 15. A nurse researcher explains the relationships between research processes and the nursing process to a group of graduate - level nursing students. Which statement by a nursing student indicates the need for further teaching? a. “Nursing research leads to evidence - based nursing practice guidelines.” b. “Nursing research has a broader focus than the nursing process.” c. “The nursing process helps to identify potential nursing research problems.” d. “The nursing process requir es rigorous application of research methods.” ANS: D The nursing process may be based on research, but does not require the rigorous application o f research methods. Nursing research may be used to develop evidence - based nursing practice guidelines. Nursing research has a broader focus than the nursing process and is generally population based rather than individual based. The nursing process can he lp to identify nursing research problems. DIF: Cognitive level: Remembering (Knowledge) 16. Research subjects in a study of body image after mastectomy will complete a questionnaire about body image after surgery. Which assumption would the researcher li kely make when conducting this study?

    a. All mastectomy patients are likely to be negatively affected by the surgery. b. Body image and appearance are important to survivors of breast cancer. c. Subjects will be able to describe a personal awareness of body imag e. d. Subjects will complete every item on the questionnaire. ANS: C Assumptions are statements taken for granted or considered true, even though they have not been scientifically tested. The researcher will assume that subjects have an awareness of this concept. The researcher does not indicate that negative effects of mastectomy are an assumption of the study. The results of the study may indicate whether this is true or not. The researcher does not indicate that the importance of body image and appearance is an assumption of the study. The results of the study may indicate whether this is true or not. The researcher does not indicate that this is an assumption of the study. It is undoubtedly hoped for to get complete data. DIF: Cogni tive level: Understanding (Comprehension) 17. Statements that will be scientifically tested as part of a research study are called a. assumptions. b. hypotheses. c. limitations. d. variables. ANS: B Hypotheses are the researcher’s best guess as to the outcome of the study. Assumptions are statements that are taken for granted or considered true, even though they have not been scientifically tested. Limitations are factors in the study that cannot be c ontrolled or manipulated, but might have an influence on the outcome. Variables are the factors influencing the hypotheses that the researcher wants to investigate. DIF: Cognitive level: Remembering (Knowledge) 18. A study that analyzes the effect of exe rcise on diabetes control among Native - American children with type II diabetes would most credibly be generalizable to which population? a. African - Americans with type II diabetes b. Native - American children with type I diabetes c. Children with type II diabet es d. All people with type II diabetes ANS: B

    Generalization is the extension of the implications of the research findings from the sample to a larger population. The population represented in the study is Native - American children, so the results of this study may be generalized to this population. Th e population that the sample represents does not include all African - Americans with type II diabetes. The population that the sample represents does not include all children with type II diabetes. The population that the sample represents does not include all patients with type II diabetes. DIF: Cognitive level: Understanding (Comprehension) 19. To evaluate data collection methodology prior to conducting a large - scale study, a researcher might carry out a smaller - scale study. This smaller - scale study is k nown as a/an a. abstract. b. exploratory design. c. pilot study. d. proposal. ANS: C A pilot study is frequently defined as a smaller version of a proposed study conducted to refine the methodology. The abstract is a synopsis of the study found at the beginning of a research report. Exploratory design is used when the total situation is un clear. A proposal is a formal request to conduct a study; it can be submitted to obtain funds or get feedback on the study’s methodology. DIF: Cognitive level: Understanding (Comprehension) 20. The nurse researcher is developing a study to examine the effects of asthma education on missed school days among grade school children. When defining the research problem in the research proposal, the nurse will discuss a. the proposed methodologies for dat a collection. b. statistics about the number of school days missed by children with asthma. c. the costs and types of various medications to treat asthma symptoms. d. the need for future studies to examine asthma care for this population. ANS: B When descr ibing the research problem, the researcher identifies an area of concern for a population. The discussion about proposed methodologies is part of the study design. The costs and types of medications would be included in background information, but this dis cussion does not identify the research problem. The discussion about the need for further studies is part of the discussion and summary. DIF: Cognitive level: Applying (Application)

    21. Which portion of a research report would the nurse initially read to get an overview of the study? a. Abstract b. Conclusion c. Framework d. Methodology ANS: A The research report usually begins with an abstract: a clear, concise summary of a study, including the research problem and purpose, methodology, and conclusions. The reader can gain an understanding of the study by reading the abstract. Conclusions are p resented at the end of the report and describe the findings based on the data collection and data analysis. The framework is present later in the study report and tells about the foundation of the study. The methodology is in the middle part of the report and describes the study methods, tools, data collection, and analysis. DIF: Cognitive level: Applying (Application) 22. The section of a research report that describes the purpose of a research study will include a. what relationships among key variable s will be examined. b. which various theories provide context for the research problem. c. what is currently understood about the research problem. d. why the research is necessary to help close a gap in knowledge. ANS: A The research purpose is a statement generated from the research problem identify ing the specific focus of goal of the study. The theoretical framework identifies how theories provide context for the research question. The literature review id entifies what is currently known about the research problem. The research problem is a statement about why the research is necessary to close gaps in knowledge. DIF: Cognitive level: Analyzing (Analysis) 23. A researcher conducts a review of relevant literature prior to developing a research study to a. avoid duplication of research ideas. b. determine which theoretical framework is best adapted to the research problem. c. determine which type of study would be most cost - effective. d. identify what is known and unknown about a problem. ANS: D

  28. Page 28
    Read page 28 as text

    The literature review is conducted to identify what is already known about a research problem and to document why a research study needs to be conducted. The literature review identifies what is known and may describe past studies, but is not necessarily p erformed to avoid duplication of research ideas since many studies are replicated to confirm results. The literature review does not evaluate the theoretical framework. The literature review does not determine cost - effectiveness of a study. DIF: Cognit ive level: Applying (Application) 24. In a qualitative study to describe stages of grief, the researcher asks parents who have lost a child to cancer to describe their experiences with grief at specific time intervals after their children’s deaths. Which assumption will the researcher make? a. Study subjects have knowledge about theoretical concepts about grief. b. Study subjects understand the concept of grief. c. Subjects will be able to articulate their feelings coherently. d. Subjects will be available for dat a collection at specific time intervals. ANS: B A researcher may assume that study subjects will understand the concept of grief. Subjects who know what grief is do not necessarily understand theoretical concepts about grief. Although it is desired t hat subjects will be able to articulate their feelings or be available at specific intervals, there is no assumption that they will be able to do so. Subjects may not always be available at specific intervals. DIF: Cognitive level: Understanding (Compre hension) 25. How is theory tested in quantitative research? a. Assumptions about the theoretical framework are evaluated. b. Concepts become more clearly defined as they are tested. c. Relationships among concepts are tested. d. The entire theory is proven or disproven. ANS: C In quantitative research, relational statements between two or more concepts are tested, not the entire theory. Assumptions are statements that are taken for g ranted and are not tested in research. Concepts are defined prior to initiating research. Quantitative studies do not prove or disprove an entire theory, just relationships among key concepts. DIF: Cognitive level: Applying (Application) 26. An operational definition of a variable or concept ensures that the variable or concept will be a. given theoretical meaning.

    b. linked to other variables or concepts. c. measured or manipulated. d. understood in context of a theoretical framework. ANS: C An operational definition of a concept allows the concept to be measured or manipulated. A conceptual definition of a concept gives that concept theoretical meaning. The research question links concepts and variables to other concepts and variables. The operational definition does not necessarily give meaning to a concept in the context of a theoretical framework. DIF: Cognitive level: Analyzing (Analysis) 27. In a research proposal, when d escribing a research design, the researcher would include a. discussion of a theoretical framework. b. evaluation of the researcher’s expertise. c. methods for measurement of variables. d. purpose of the study. ANS: C In the research design, the researcher will describe how variables are measured along with sampling procedures and plans for data collection and analysis. The theoretical framework is discussed in the theory section. The evaluation of the researcher’s expe rtise is part of the discussion. The purpose of the study is discussed in the introduction and purpose section. DIF: Cognitive level: Analyzing (Analysis) 28. Prior to initiating a large - scale research study, the researcher conducts a small - scale stud y using similar subjects, methods, instruments, measurements, and analysis. This is done to a. define the conceptual framework of the study. b. determine the quality of the study components. c. link study variables to one another. d. provide a study design. ANS: B A pilot study is performed on a smaller scale to determine the quality of the study components before the study is conducted on a larger scale. The pilot is not performed to define the conceptual framework of the study. The pilot does not necessa rily link study variables to one another and is not the purpose of performing a pilot study. The pilot study tests components of the study design, which has already been determined.

    DIF: Cognitive level: Analyzing (Analysis) 29. The methodology portio n of the research report is used to a. describe the study design. b. discuss the implications of the study. c. provide a theoretical framework for the study. d. summarize the purpose, methods, and results. ANS: A In the methodology section, the researcher describes the study design including sampling methods, measurement of variables, data collection, and data analysis. The implications of the study are explored in the discussion section. The theoretical framework is discussed in the introduction. The summary is discussed in the conclusion. DIF: Cognitive level: Understanding (Comprehension) 30. When the researcher describes the population of a study, the research consumer understands that this represents a. all members of the population at large. b. all people who meet inclusion criteria for the study. c. members of the study group and the control grou p. d. subjects selected for the study based on sampling techniques. ANS: B The population is all people who meet inclusion criteria for the study whether they are sampled and included or not. Not all members of the population at large meet inclusion cr iteria and those who do not are not considered part of the population being studied. Members of the study and control group are the sample of the population selected for participation in the study. Subjects selected for the study are a representative sampl e of the population. DIF: Cognitive level: Applying (Application) 31. When a researcher describes an instrument as being valid this indicates that the instrument a. accurately measures a variable. b. consistently measures variables across studies. c. has been described as high quality by other researchers. d. has been routinely used in other, similar studies. ANS: A

    When an instrument is valid, it is considered to be accurate. Reliability of an instr ument means that it is consistent across studies. Quality of the instrument is not defined by validity measures. Frequency of use of the instrument is not defined by validity measures. DIF: Cognitive level: Analyzing (Analysis) 32. The level of measur ement determines the type of statistical analysis that can be performed on the data. The level of measurement that describes the lowest form of measurement is a. interval. b. ordinal. c. nominal. d. ratio. ANS: C Nominal is the lowest form of measurement, followed by ordinal, and interval. Ratio is considered the highest form of measurement. DIF: Cognitive level: Understanding (Comprehension) 33. When noting the limitations of a research study, the nurse might ma ke which observation? a. Abstract concepts were defined using concrete, consistent terms. b. Findings could not be generalized to a population not included in the study. c. The researcher included a discussion of the links between the study’s variables. d. The sub jects were randomly assigned to control and experimental groups. ANS: B Limitations are restrictions in a study methodology or framework that may decrease the credibility and generalizability of the findings. The definition of concepts does not address the limitations of a study. The theoretical framework contains a discussion about the links between study variables. Random assignment to control and experimental groups increases the likelihood that the study’s findings may be generalized to a larger population. DIF: Cognitive level: Analyzing (Analysis) 34. The purpose of a study abstract is to a. describe the reason for conducting the study. b. outline the theoretical framework that defines the study. c. summarize a study concisely and capture the reader’s attention. d. summarize previous research about the study’s topic.
