5366 Principles of Research in Nursing |
Actual Q&A with Rationale (NURS5366
Module 2 Exam) | The University of Texas
at Arlington
1. A researcher is studying the effect of a new wound care protocol on the healing time of
pressure ulcers. In this study, what is the healing time?
A. Independent variable
B. Dependent variable
C. Extraneous variable
D. Confounding variable
Answer: B
Rationale: The Dependent variable represents the outcome or response that the
researcher is interested in measuring. In this specific clinical scenario, the healing time is
what changes in response to the intervention being tested. Understanding the relationship
between these variables is essential for evaluating the effectiveness of nursing
interventions.
2. Which principle of the Belmont Report requires that researchers treat participants as
autonomous agents and provide special protections for those with diminished autonomy?
A. Respect for persons
,B. Justice
C. Beneficence
D. Non-maleficence
Answer: A
Rationale: The principle of Respect for persons is fundamental to ethical research and is
primarily operationalized through the process of informed consent. This principle ensures
that individuals can choose whether or not to participate without coercion. It also
mandates that vulnerable populations receive extra safeguards to prevent exploitation.
3. A nursing student is reviewing a research article written by the original investigators who
conducted the study. This is an example of what type of source?
A. Primary source
B. Tertiary source
C. Secondary source
D. Peer-reviewed review
Answer: A
Rationale: A Primary source is the direct account of a research study written by the
individuals who actually performed the investigation. These sources provide the most
detail regarding the methodology, data collection, and analysis used in the study. Utilizing
these sources is critical for conducting a rigorous and accurate literature review in nursing.
, 4. What is the primary purpose of the Institutional Review Board (IRB) in the research
process?
A. To protect the rights and welfare of human subjects
B. To ensure the statistical validity of the study
C. To secure funding for the research project
D. To publish the final results of the study
Answer: A
Rationale: The fundamental role of the IRB is To protect the rights and welfare of human
subjects involved in research. They review study protocols to ensure that risks are
minimized and that ethical standards are strictly followed. Without approval from this
board, researchers cannot proceed with data collection involving human participants.
5. A hypothesis that states, ‘There is no difference in the level of anxiety between patients
who receive music therapy and those who do not,’ is an example of a:
A. Directional hypothesis
B. Research hypothesis
C. Null hypothesis
D. Complex hypothesis
Answer: C
