1. The measures used by a nurse researcher to maintain uniformity of conditions in a quantitative
research study refer to which aspect of the study?
a. Accuracy
b. Methods
c. Control
d. Validity
ANS: C
Feedback
A Accuracy refers to all aspects of a study systematically and logically following
from the research question.
B Methods refers to sections of the research study that include sampling, data
collection, and data analysis.
C Control is the term used for measures taken by the researcher to keep the
conditions of a study uniform.
D Validity refers to the truthfulness or soundness of a study.
DIF: Cognitive Level: Remembering (Knowledge) REF: Page 165
2. What is the overall purpose of the research design in a quantitative research study?
a. To determine sample size
b. To identify the problem statement
c. To assist the researcher in identifying gaps in the knowledge base
d. To provide the plan for answering the research question
ANS: D
Feedback
A Sample size is determined by the chosen design or by a power analysis.
B The problem statement describes the general focus of the research study.
C Gaps in knowledge should be identified and synthesized in the literature review.
D The purpose of the research design is to provide the plan for answering the
research question(s).
DIF: Cognitive Level: Understanding (Comprehension) REF: Page 165
3. In which of these ways does the nurse researcher’s literature review help select the appropriate
study design?
a. By enlarging the scope of the study’s hypotheses
b. By objectively assessing available knowledge of the area

c. By comparing current findings with previous study findings
d. By ensuring faithfulness to the study’s purpose
ANS: B

Feedback
A The literature review gives the researcher clues about the direction and nature of
the hypotheses but not necessarily their scope.
B Objectivity in the conceptualization of the research question is derived from a
thorough review of the literature.
C The literature review does give information about past studies, but the research
design is obtained by considering the best approach to answer the research
question.
D The literature review does not ensure fidelity to study purpose; the research
design serves this role.

4. When reviewing a research report, the nurse determines that all aspects of a study
systematically and logically follow from the research problem. Which condition has been
met?
a. Accuracy
b. Feasibility
c. Internal validity
d. External validity
ANS: A
Feedback
A Accuracy indicates that all aspects of a study systematically and logically flow
from the research question.
B Feasibility refers to a study’s pragmatic concerns (e.g., availability of subjects,
time required).
C Internal validity refers to whether the independent variable made the change in
the dependent variable.
D External validity refers to the generalizability of the investigation’s findings to
additional populations and other environmental conditions.
DIF: Cognitive Level: Understanding (Comprehension) REF: Page 165-166
5. Which factor is most likely to be a mediating variable in a study to determine if high doses of
vitamin C help reduce the subjects’ susceptibility to influenza?
a. The subjects’ use of influenza vaccine
b. The subject’ knowledge of vitamin C’s functions
c. The gender of the potential subjects
d. The marital status of the potential subjects
ANS: A
Feedback
A An extraneous or mediating variable is one that interferes with the operations of
the variables being studied, such as the study’s outcome, which is susceptibility to
influenza.
B A subject’s knowledge of vitamin C’s functions is not likely to act as a mediating
variable in this study.
