1. Which element is most important when defining a capstone project's
PICOT question?
A. Sample size
B. Feasibility
C. Specificity of population, intervention, comparison, outcome, time
D. Budget
Rationale: A clear, specific PICOT frames the project scope and guides
methodology and feasibility.
2. The primary purpose of a literature review in a capstone is to:
A. Prove the student read widely
, B. Identify gaps and justify the project
C. Meet graduation requirements
D. Summarize textbooks
Rationale: The literature review demonstrates existing knowledge
and reveals gaps the capstone will address.
3. Which IRB category typically applies to quality improvement projects
with minimal risk?
A. Full board review
B. Exempt or expedited review
C. Emergency review
D. FDA-mandated review
Rationale: QI projects with minimal risk often qualify for exempt or
expedited IRB pathways.
4. Best method to measure fidelity of an implemented clinical
intervention is:
A. Patient satisfaction only
B. Cost analysis
C. Direct observation and checklist scores
D. Publication count
Rationale: Direct observation using standardized checklists provides
objective fidelity data.
5. Which statistic is appropriate for comparing pre/post intervention
means in the same sample?
, A. Independent t-test
B. Paired t-test
C. Chi-square test
D. ANOVA
Rationale: Paired t-test accounts for within-subject correlation when

A. Translate it to multiple languages
B. Calculate internal consistency (Cronbach's alpha)
C. Shorten the survey to 3 items
D. Use face validity only
Rationale: Internal consistency metrics like Cronbach's alpha quantify
reliability across items.
9. For a cohort study measuring incidence over time, the preferred
measure is:
A. Prevalence ratio
B. Odds ratio
C. Incidence rate
D. Hazard ratio only
Rationale: Incidence rate measures new cases per person-time,
suitable for cohort studies.
10. Which method most reduces selection bias in intervention
studies?
A. Convenience sampling
B. Voluntary enrollment
C. Randomization
D. Purposive sampling
