Introduction
This assessment evaluates comprehensive knowledge and application of evidence-based practice principles essential for healthcare professionals.
The exam assesses skills in formulating research questions, identifying appropriate study designs, evaluating evidence quality, conducting
literature searches, interpreting statistical data, implementing clinical changes, and understanding ethical and regulatory requirements. The
multiple-choice and scenario-based format emphasizes real-world application and critical decision-making in clinical practice. Candidates will
demonstrate ability to translate research evidence into practice while maintaining patient safety, ethical standards, and professional
accountability. Success requires both theoretical understanding and practical application of EBP frameworks in diverse healthcare settings.
SECTION ONE: QUESTIONS 1–100
Question 1
A nurse is preparing to develop an evidence-based practice project to reduce catheter-associated urinary tract infections. What is the FIRST step the
nurse should take?
A. Implement the new protocol on the unit
B. Formulate a clear, focused clinical question
C. Conduct a thorough literature search
D. Evaluate the outcomes after implementation
,🟢 Correct answer
🔴 Explanation: The first step in evidence-based practice is formulating a clear, focused clinical question using frameworks like PICOT. This guides
the entire EBP process by defining what evidence is needed. Implementing protocols (A), searching literature (C), and evaluating outcomes (D) occur
after the question is established.
Question 2
Which of the following best represents the highest level of evidence in the hierarchy of research studies for intervention effectiveness?
A. Case-control study
B. Randomized controlled trial
C. Systematic review of randomized controlled trials
D. Cohort study
🟢 Correct answer
🔴 Explanation: Systematic reviews of randomized controlled trials represent the highest level of evidence (Level I) because they synthesize multiple
high-quality RCTs, reducing bias and increasing reliability. Individual RCTs (B) are Level II, cohort studies (D) are Level III, and case-control studies
(A) are Level IV.
Question 3
A nurse researcher is using the PICOT format to develop a research question. What does the "T" in PICOT represent?
A. Treatment
B. Timeframe
C. Type of study
D. Team members
🟢 Correct answer
🔴 Explanation: In PICOT, "T" stands for Timeframe, which specifies the duration over which outcomes will be measured. This helps create a
focused, answerable question. Treatment (A), Type of study (C), and Team members (D) are not components of the PICOT framework.
,Question 4
Which database is MOST appropriate for conducting a comprehensive literature search on nursing interventions?
A. Google
B. CINAHL (Cumulative Index to Nursing and Allied Health Literature)
C. PubMed
D. PsycINFO
🟢 Correct answer
🔴 Explanation: CINAHL is the premier database specifically for nursing and allied health literature, providing comprehensive coverage of nursing
interventions. While PubMed (C) is valuable for medical research, CINAHL is more nursing-specific. Google (A) lacks scholarly filtering, and
PsycINFO (D) focuses on psychology.
Question 5
A study reports a p-value of 0.03. What does this indicate about statistical significance?
A. The results are not statistically significant
B. The results are statistically significant at the 0.05 level
C. The results are significant only at the 0.01 level
D. The p-value indicates the effect size
🟢 Correct answer
🔴 Explanation: A p-value of 0.03 is less than the conventional alpha level of 0.05, indicating statistical significance. It means there's a 3%
probability that the observed results occurred by chance. The results would not be significant at 0.01 (C), and p-values do not indicate effect size (D).
Question 6
Which ethical principle requires that researchers protect participants from harm and minimize risks?
, A. Justice
B. Beneficence
C. Autonomy
D. Confidentiality
🟢 Correct answer
🔴 Explanation: Beneficence is the ethical principle requiring researchers to maximize benefits and minimize harms to participants. Justice (A)
involves fair distribution of benefits and risks. Autonomy (C) relates to informed consent and self-determination. Confidentiality (D) protects
participant identity but is not the primary principle for harm protection.
Question 7
A nurse wants to implement evidence-based practice changes but faces resistance from staff. Which strategy is MOST effective for facilitating
change?
A. Implement the change without staff input to ensure consistency
B. Involve staff in the decision-making process and provide education
C. Wait until management mandates the change
D. Exclude resistant staff from the implementation team
🟢 Correct answer
🔴 Explanation: Involving staff in decision-making and providing education addresses resistance through engagement, ownership, and knowledge.
This change management approach is evidence-based and most effective. Implementing without input (A) increases resistance. Waiting for mandates
(C) delays improvement. Excluding staff (D) creates division.
Question 8
Which study design is MOST appropriate for investigating the cause-effect relationship between an intervention and outcome?
A. Descriptive study
B. Cross-sectional study
C. Randomized controlled trial
D. Qualitative study
