Practice | Test Bank & Questions, Answers with
Rationales
Section 1: Foundations of Evidence-Based Practice
1. What is the primary purpose of evidence-based practice (EBP) in
nursing?
A. To replace clinical judgment
B. To integrate best evidence with clinical expertise and patient
preferences
C. To eliminate the need for nursing research
D. To standardize care for every patient
Answer: B
Rationale: EBP integrates the best available research evidence with
clinical expertise and patient preferences to guide individualized
care.
2. Which component is essential to evidence-based nursing
practice?
A. Tradition alone
B. Provider preference alone
C. Best available evidence
D. Hospital policy alone
Answer: C
Rationale: Best available evidence is one of the core components of
EBP.
3. A nurse uses research findings, clinical experience, and the
patient's preferences when developing a care plan. Which concept is
demonstrated?
A. EBP
B. Randomization
C. Blinding
D. Meta-analysis
,Answer: A
Rationale: EBP combines research evidence, clinical expertise, and
patient values/preferences.
4. Which statement best distinguishes EBP from research?
A. EBP only involves qualitative studies.
B. Research generates new knowledge, whereas EBP applies existing
evidence to practice.
C. Research is always performed by nurses.
D. EBP does not require evaluation.
Answer: B
Rationale: Research generates knowledge; EBP evaluates and
applies available evidence to clinical decision-making.
5. Which factor represents patient preference in EBP?
A. Published research findings
B. Nurse's years of experience
C. Patient's treatment goals and values
D. Hospital staffing ratio
Answer: C
Rationale: Patient preferences, values, goals, and circumstances are
central to individualized evidence-based care.
6. What is the first step in many EBP models?
A. Implement the intervention
B. Evaluate outcomes
C. Ask a clinical question
D. Publish the results
Answer: C
Rationale: EBP commonly begins by identifying a clinical problem
and developing an answerable question.
7. Which action demonstrates use of clinical expertise?
A. Searching only one database
B. Applying assessment skills to determine whether evidence fits a
patient
,C. Ignoring patient preferences
D. Selecting the newest article automatically
Answer: B
Rationale: Clinical expertise helps clinicians interpret and apply
evidence appropriately to individual patients.
8. Which statement about EBP is accurate?
A. It guarantees identical outcomes for all patients.
B. It eliminates clinical judgment.
C. It supports informed clinical decision-making.
D. It uses only randomized controlled trials.
Answer: C
Rationale: EBP supports clinical decisions by integrating evidence
with expertise and patient circumstances.
9. A nurse questions whether a commonly used intervention
remains effective. What should the nurse do first?
A. Immediately discontinue the intervention
B. Formulate a focused clinical question
C. Contact the media
D. Conduct a meta-analysis independently
Answer: B
Rationale: A focused clinical question provides direction for an
evidence search.
10. Which is a potential benefit of EBP?
A. Increased reliance on tradition
B. Improved quality and safety of care
C. Elimination of patient participation
D. Reduced need for assessment
Answer: B
Rationale: EBP can improve quality, safety, outcomes, and efficiency
of care.
, Section 2: Asking Clinical Questions and PICOT
11. What does the “P” in PICOT usually represent?
A. Publication
B. Population or patient
C. Procedure
D. Probability
Answer: B
Rationale: P identifies the patient population, problem, or
condition.
12. In PICOT, what does “I” represent?
A. Intervention
B. Information
C. Investigation
D. Incidence
Answer: A
Rationale: I identifies the intervention, exposure, or treatment being
considered.
13. What does “C” represent in PICOT?
A. Clinical outcome
B. Comparison
C. Cohort
D. Control variable
Answer: B
Rationale: C identifies the comparison intervention or usual care.
14. What does “O” represent in PICOT?
A. Observation
B. Outcome
C. Organization
D. Odds
Answer: B
Rationale: O identifies the desired measurable clinical outcome.
