NUR 381 NURSING RESEARCH METHODS AND EVIDENCE-BASED
PRACTICE FINAL EXAMINATION PRACTICE QUESTIONS AND
ANSWERS WITH VERIFIED SOLUTIONS LATEST 2026-2027 UPDATE
Instructions: Answer all sixty (60) practice questions. Select the single best option for each
multiple-choice question. Highlighted options indicate correct answers along with verified solutions
and comprehensive rationales.
1. A nurse researcher formulates a clinical question using the PICOT format to evaluate
the effectiveness of position changes in reducing pressure injuries. What component
does the letter "I" represent in this framework?
A) Implementation timeline
B) Intervention or interest area
C) Institutional policy
D) Individual patient preference
Rationale: In the PICOT acronym (Population, Intervention, Comparison, Outcome, Timeframe), "I" stands for the
specific treatment, exposure, or intervention being evaluated.
2. Which research design provides the highest level of evidence on the hierarchy of
evidence pyramid to support clinical practice interventions?
A) Single qualitative phenomenological study
B) Well-designed cohort study
C) Systematic review or meta-analysis of randomized controlled trials (RCTs)
D) Expert opinion or clinical committee report
Rationale: Systematic reviews and meta-analyses synthesizing multiple rigorous RCTs minimize bias and offer
the highest level of evidence for clinical practice decisions.
3. What essential feature distinguishes a true experimental research design (randomized
controlled trial) from a quasi-experimental design?
A) Random assignment of participants to experimental and control groups
B) Use of a pre-test assessment measure
C) Administration of a specialized intervention
D) Collection of quantitative numerical data
Rationale: True experimental designs require three core criteria: manipulation of an independent variable, a
control group, and random assignment. Quasi-experimental designs lack randomization or a control group.
, 4. A researcher measures patient anxiety levels using a standardized scale before and
after a music therapy session. What type of variable is the anxiety level in this study?
A) Independent variable
B) Dependent variable
C) Extranenous variable
D) Demographic variable
Rationale: The dependent variable represents the outcome or effect that is measured to determine the impact of
the manipulated independent variable (music therapy).
5. What ethical principle from the Belmont Report guarantees that study participants are
fully informed of research risks and benefits, making voluntary decisions to participate?
A) Respect for Human Autonomy
B) Beneficence
C) Justice
D) Fidelity
Rationale: Respect for autonomy requires that individuals are treated as autonomous agents through voluntary,
informed consent processes.
6. A nurse researcher conducts a qualitative study exploring the lived experiences of
patients recovering from severe sepsis in the ICU. Which qualitative research approach
is being used?
A) Grounded theory
B) Phenomenology
C) Ethnography
D) Historical research
Rationale: Phenomenology focuses specifically on understanding and describing the lived human experiences of
a particular phenomenon.
7. In quantitative data analysis, what statistic measures the probability that study
findings occurred purely by random chance?
A) p-value (significance level)
B) Mean standard deviation
C) Correlation coefficient (r)
D) Cronbach's alpha
Rationale: The p-value indicates the probability of a Type I error; a p-value less than 0.05 generally indicates
statistically significant results unlikely due to chance.
8. What sampling method selects participants based on specific personal characteristics
to ensure rich, in-depth qualitative data collection?
