1. Which best describes evidence-based practice (EBP)?
A. Practice based only on expert opinion
B. Integration of best research, clinical expertise, and patient
values
C. Practice based on hospital policy only
D. Use of outdated clinical guidelines
Rationale: EBP combines research evidence, clinical expertise,
and patient preferences for optimal care.
Correct Answer: B
2. A Type I error in research occurs when:

B. True null hypothesis is rejected
C. Sample size is too large
D. Data is missing
Rationale: Type I error = rejecting a true null hypothesis.
Correct Answer: B
3. The primary purpose of randomization in clinical trials is to:
,A. Increase sample bias
B. Reduce confounding variables
C. Ensure qualitative data
D. Decrease validity
Rationale: Randomization reduces selection bias and
confounders.
Correct Answer: B
4. Which is a hallmark of qualitative research?
A. Large sample size
B. Numerical data
C. Exploration of lived experiences
D. Randomized control groups
Rationale: Qualitative research explores meaning and
experiences.
Correct Answer: C

quality?
A. Mortality rate
B. Infection rate
C. Hand hygiene compliance
D. Readmission rate
Rationale: Leading indicators predict outcomes (e.g.,
compliance).
Correct Answer: C
10. The primary purpose of a theoretical framework is to:
A. Replace research
B. Guide study design and interpretation
C. Eliminate data collection
D. Avoid hypotheses
Rationale: Frameworks guide research structure.
