A nurse is developing a clinical question using the PICO format. Which component
represents the "C"?
a. The population of interest
b. The outcome of the intervention
c. The comparison intervention or standard care
d. The time frame of the study
✔️ Correct Answer: C
Rationale:
In PICO, "C" stands for Comparison, which refers to the alternative intervention or
standard care used to evaluate the effectiveness of the primary intervention.
NCLEX focus: research fundamentals and PICO framework.
,A nurse is reviewing a study that manipulates one variable to observe its effect on
another. What type of study is this?
a. Descriptive study
b. Experimental study
c. Qualitative study
d. Correlational study
✔️ Correct Answer: B
Rationale:
Experimental studies involve manipulation of an independent variable to
determine its effect on a dependent variable. NCLEX focus: research design and
experimental research.
Which characteristic best describes a randomized controlled trial (RCT)?
a. No comparison group
b. Random assignment to groups
c. Retrospective data analysis
d. Purely observational design
✔️ Correct Answer: B
Rationale:
RCTs randomly assign participants to intervention or control groups to reduce bias
and strengthen causality. NCLEX focus: experimental design and evidence-based
practice.
,A nurse reads a p-value of 0.01. What does this indicate?
a. The results are not significant
b. There is a 1% probability results are due to chance
c. The study is clinically significant
d. The null hypothesis is accepted
✔️ Correct Answer: B
Rationale:
A p-value of 0.01 indicates a 1% likelihood that results occurred by chance,
suggesting statistical significance. NCLEX focus: statistics basics and data analysis.
What does a Type I error represent in research?
a. Failing to reject a false null hypothesis
b. Rejecting a true null hypothesis
c. Incorrect data collection
d. Small sample size error
✔️ Correct Answer: B
Rationale:
A Type I error occurs when a true null hypothesis is incorrectly rejected (false
positive). NCLEX focus: statistical errors and research statistics.
A nurse is reviewing qualitative research. Which data collection method is most
appropriate?
, a. Blood pressure readings
b. Structured surveys with numbers
c. In-depth interviews
d. Laboratory test results
✔️ Correct Answer: C
Rationale:
Qualitative research focuses on lived experiences and uses interviews, focus
groups, and observations. NCLEX focus: qualitative methods and research
approaches.
What is the primary purpose of a systematic review?
a. Collect primary patient data
b. Summarize expert opinion
c. Synthesize findings from multiple studies
d. Conduct interviews with participants
✔️ Correct Answer: C
Rationale:
Systematic reviews critically analyze and combine multiple studies to provide high-
level evidence. NCLEX focus: evidence synthesis and evidence-based practice.
Which sampling method gives every member of a population an equal chance of
selection?
