EXAM OVERVIEW
Course: Nursing Research & Evidence-Based Practice
Institution: Generic Nursing School
Exam Type: Comprehensive Exam
Question Count: 100 Questions
Format: Multiple Choice with Verified Answers and Complete Rationales
Focus Areas: Nursing research principles, evidence-based practice, research methodologies, statistics, ethics in
research, and application of evidence to clinical practice
QUESTION 1
A nurse is implementing evidence-based practice (EBP) on a medical-surgical unit. Which step should the
nurse take FIRST in the EBP process?
A) Search for the best evidence
B) Formulate a clinical question
C) Appraise the evidence
D) Implement the evidence
Correct Answer: B
Rationale: The first step in the EBP process is to formulate a clinical question using the PICO format.
Searching for evidence (A), appraising evidence (C), and implementing evidence (D) follow the formulation
of the clinical question.
QUESTION 2
A nurse is using the PICO format to formulate a clinical question. What does the "I" in PICO represent?

B) Issue
C) Indicator
D) Impact
,2
Correct Answer: A

Intervention being considered. Issue (B), Indicator (C), and Impact (D) are not correct.
QUESTION 3
A nurse is evaluating a research study. Which level of evidence is considered the strongest?
A) Randomized controlled trial
B) Systematic review and meta-analysis
C) Cohort study
D) Case-control study

Rationale: Systematic reviews and meta-analyses are considered the highest level of evidence. Randomized
controlled trials (A) are strong but not as strong as systematic reviews. Cohort studies (C) and case-control
studies (D) are lower levels of evidence.

A) Randomized controlled trial (RCT)
B) Cohort study
C) Case-control study
D) Cross-sectional study
Correct Answer: A
Rationale: The randomized controlled trial (RCT) is considered the gold standard for establishing causality.

A) P-value
B) Confidence interval
C) Odds ratio
D) Mean
Correct Answer: C
Rationale: The odds ratio indicates the strength of association between two variables. The p-value (A)

C) Resistance to change
D) All of the above
Correct Answer: D
Rationale: Common barriers to EBP implementation include lack of time (A), lack of resources (B), and
resistance to change (C). All are common barriers.
QUESTION 9
A nurse is critically appraising a research article. Which question should the nurse ask to evaluate the study's
validity?
A) Were the study participants randomly assigned?
B) Were the measurement tools reliable?
C) Were the results clinically significant?
D) All of the above
Correct Answer: D
Rationale: Evaluating validity includes assessing random assignment (A), reliability of measurement tools (B),
