Principles of Research in Nursing | Actual
Q&A with Rationale (NURS5366 Final
Exam) | The University of Texas at
Arlington
1. Which ethical principle from the Belmont Report ensures that researchers treat
participants as autonomous agents and protect those with diminished autonomy?
A. Respect for persons
B. Beneficence
C. Justice
D. Non-maleficence
Answer: A
Rationale: The principle of respect for persons is the foundation for obtaining informed
consent from participants. It recognizes that individuals should be treated as autonomous
beings capable of making their own decisions. Researchers must also provide extra
protections for vulnerable populations who cannot fully exercise autonomy.
2. A researcher is studying the effect of a new wound care protocol on healing time. In this
study, what is the ‘healing time’ considered?
A. Dependent variable
,B. Extraneous variable
C. Confounding variable
D. Independent variable
Answer: A
Rationale: The dependent variable represents the outcome or effect that the researcher is
interested in measuring. In this scenario, healing time is expected to change based on the
intervention provided. The wound care protocol itself would be the independent variable
being manipulated.
3. Which type of quantitative research design is most appropriate for determining a cause-
and-effect relationship between variables?
A. Correlational design
B. Quasi-experimental design
C. Descriptive design
D. Experimental design
Answer: D
Rationale: Experimental designs are characterized by randomization, control groups, and
manipulation of the independent variable to establish causality. This rigorous structure
helps eliminate alternative explanations for the findings. Other designs like correlational or
descriptive only identify relationships or patterns without proving cause.
, 4. A nurse researcher conducts a study to describe the lived experience of mothers caring for
children with terminal illnesses. Which qualitative tradition is being used?
A. Phenomenology
B. Ethnography
C. Grounded theory
D. Historical research
Answer: A
Rationale: Phenomenology focuses on understanding the ‘essence’ of a human experience
or phenomenon. It typically involves in-depth interviews to capture how individuals
perceive their reality. The goal is to provide a rich description of the participants’ lived
world.
5. What is the primary purpose of an Institutional Review Board (IRB) in the research
process?
A. To ensure the statistical validity of the study results
B. To provide funding for nursing research projects
C. To protect the rights and welfare of human subjects
D. To assist researchers in publishing their findings
Answer: C
