5366 Principles of Research in Nursing |
Actual Q&A with Rationale (NURS5366
Module 2 Exam) | The University of Texas
at Arlington
1. When a researcher ensures that the selection of subjects is fair and that the benefits and
risks of the study are shared across groups, which Belmont Report principle is being applied?
A. Beneficence
B. Respect for Persons
C. Justice
D. Autonomy
Answer: C
Rationale: The principle of Justice requires that researchers use fair procedures to select
subjects and distribute the burdens and benefits of research equitably. This principle is
violated when certain populations, such as the poor or minorities, are targeted for risky
research while wealthier populations receive the benefits. Adhering to Justice ensures that
no single group is unduly burdened by research involvement.
2. Which type of variable is the researcher attempting to control or hold constant to prevent
it from influencing the outcome of the study?
A. Extraneous Variable
,B. Independent Variable
C. Dependent Variable
D. Demographic Variable
Answer: A
Rationale: An Extraneous Variable is any variable that is not the main focus of the study
but may influence the relationship between the independent and dependent variables.
Researchers use various methods, such as inclusion criteria or randomization, to control
for these variables. If an Extraneous Variable is not controlled, it can confound the results
and make the findings less reliable.
3. A researcher is conducting a study on the effect of a new wound care protocol on healing
time. In this study, the healing time is considered the:
A. Independent Variable
B. Attribute Variable
C. Dependent Variable
D. Confounding Variable
Answer: C
Rationale: The Dependent Variable represents the outcome or response that the
researcher is interested in measuring or explaining. In this scenario, healing time is the
, outcome that changes in response to the intervention. Therefore, Dependent Variable is the
correct term for the outcome being observed after the protocol is applied.
4. A nurse researcher finds a summary of a study written by an author who did not conduct
the original research. This is an example of a:
A. Primary Source
B. Tertiary Source
C. Secondary Source
D. Peer-reviewed Source
Answer: C
Rationale: A Secondary Source is a summary or interpretation of a study performed by
someone other than the original investigator. While useful for finding primary sources, a
Secondary Source should not be the main focus of a rigorous literature review because it
can introduce bias or misinterpretations. Researchers are encouraged to find the primary
source to ensure the highest level of accuracy for their work.
5. Which of the following describes a ‘Null Hypothesis’?
A. A statement predicting a positive relationship between variables.
B. A statement predicting a negative relationship between variables.
C. A statement predicting a difference in groups but not the direction.
D. A statement that no relationship exists between the variables being studied.
