Nurs 504/Nur 504 final Exam 2026-2027 BANK QUESTIONS
WITH DETAILED VERIFIED ANSWERS EXAM QUESTIONS

1. A nurse researcher is designing a study to examine the effect of a
new wound care dressing on healing times in diabetic patients. The
researcher randomly assigns participants to either the experimental
dressing or the standard dressing. This study design is best described
as:
A) Quasi-experimental
B) Correlational
C) Randomized controlled trial
D) Descriptive
Answer: C) Randomized controlled trial
Explanation: A randomized controlled trial (RCT) is the gold standard for
experimental research. It involves random assignment of participants to
experimental and control groups, manipulation of an independent
variable, and measurement of a dependent variable. This design
provides the strongest evidence for cause-and-effect relationships
because randomization helps control for confounding variables and
selection bias.

2. Which level of evidence according to the Johns Hopkins Nursing
Evidence-Based Practice model provides the strongest evidence for
clinical decision-making?
A) Level I
B) Level II
C) Level III
D) Level IV
Answer: A) Level I
Explanation: In the Johns Hopkins model, Level I represents the highest
level of evidence and includes systematic reviews of randomized
controlled trials, meta-analyses, and evidence-based clinical practice
guidelines based on systematic reviews. These sources synthesize
multiple high-quality studies to provide the most reliable evidence for
practice.
3. A researcher wants to understand the lived experience of nurses who
have cared for patients during a pandemic. The most appropriate
qualitative research design for this inquiry is:
A) Grounded theory
B) Phenomenology
C) Ethnography
D) Case study
Answer: B) Phenomenology
Explanation: Phenomenology is the qualitative approach specifically
designed to explore and describe the lived experiences of individuals
,3|Page
regarding a particular phenomenon. It seeks to understand the essence
of the experience from the participant's perspective, making it ideal for
studying the subjective experiences of nurses during a pandemic.
4. The primary purpose of the Institutional Review Board (IRB) in
nursing research is to:
A) Ensure the study has adequate funding
B) Protect the rights and welfare of human subjects
C) Review the statistical methods of the study
D) Publish the research findings
Answer: B) Protect the rights and welfare of human subjects
Explanation: The IRB's fundamental responsibility is to protect human
subjects in research. This includes reviewing study protocols to ensure
that risks are minimized, informed consent is properly obtained, and
that the rights, dignity, and welfare of participants are safeguarded in
accordance with federal regulations and ethical principles.
5. A study reports a p-value of 0.03. This means:
A) There is a 3% chance that the results are due to chance
B) The null hypothesis is definitely false
C) The results are clinically significant
D) There is a 97% chance that the results are due to the intervention
Answer: A) There is a 3% chance that the results are due to chance
, 4|Page
Explanation: The p-value represents the probability that the observed
results would occur if the null hypothesis were true. A p-value of 0.03
indicates a 3% probability that the findings occurred by random chance
alone. Since this is less than the conventional alpha of 0.05, we reject
the null hypothesis and conclude that the results are statistically
significant.
6. Which ethical principle is most directly addressed by obtaining
informed consent from research participants?
A) Beneficence
B) Justice
C) Respect for persons
D) Nonmaleficence
Answer: C) Respect for persons
Explanation: The principle of respect for persons requires that
individuals be treated as autonomous agents and that those with
diminished autonomy be protected. Informed consent is a direct
application of this principle, ensuring that participants have the right to
make informed decisions about their participation, including the right to
withdraw at any time without penalty.
7. A nurse researcher is using a survey to collect data on patient
satisfaction. The researcher sends the survey to 500 patients and
receives 150 completed surveys. This scenario describes:
A) Sampling error
B) Response bias
