Core Domains Assessed:
• Evidence-Informed Practice Foundations
• Research Methodology & Design
• Critical Appraisal of Literature
• Data Interpretation & Analysis
• Knowledge Translation & Application
• Ethical Considerations in Research
• Clinical Decision-Making
This examination assesses the candidate’s ability to critically evaluate
research evidence and apply evidence-informed decision-making within
professional practice contexts. Candidates are expected to demonstrate
advanced analytical reasoning, interpretation of quantitative and qualitative
data, and the ability to synthesize findings into practical applications. The
assessment reflects contemporary standards in scholarly inquiry and
professional nursing practice.
Candidates must read each question carefully and select the most appropriate
answer. This examination contains approximately 85 questions and must be
completed within the allocated time. No external materials are permitted
,unless explicitly stated. Ensure that all responses are clearly marked. Partial
credit is not awarded.

Questions
Q1. A nurse researcher evaluates a randomized controlled trial (RCT)
investigating a new intervention for pressure ulcer prevention. Which factor
most strongly supports the internal validity of the study?
A. Large sample size
B. Random allocation of participants
C. Use of convenience sampling
D. Inclusion of multiple sites
Correct Answer: B. Random allocation of participants
Explanation:
Random allocation minimizes selection bias and ensures comparable
groups, directly strengthening internal validity. A large sample size (A)
improves power but not necessarily validity. Convenience sampling (C)
weakens validity. Multiple sites (D) enhance generalizability, not internal
validity.
Q2. A qualitative study explores patient experiences with chronic pain using in-
depth interviews. Which method enhances the credibility of the findings?
A. Statistical significance testing
B. Triangulation of data sources
C. Increasing sample size beyond saturation
D. Using closed-ended questions
,Correct Answer: B. Triangulation of data sources
Explanation:
Triangulation strengthens credibility by confirming findings through
multiple perspectives. Statistical testing (A) is irrelevant in qualitative research.
Increasing sample size (C) beyond saturation adds little value. Closed-ended
questions (D) limit depth.
Q3. A clinician reads a systematic review and meta-analysis. What is the
primary advantage of this type of study?
A. It generates new primary data
B. It combines results to increase statistical power
C. It eliminates all forms of bias
D. It focuses on a single patient population
Correct Answer: B. It combines results to increase statistical power
Explanation:
Meta-analyses pool data to improve precision and power. They do not
generate primary data (A), eliminate all bias (C), or necessarily focus on one
population (D).
Q4. A study reports a p-value of 0.03. How should this result be interpreted?
A. The null hypothesis is proven true
B. There is a 3% chance the results are correct
C. The findings are statistically significant
D. The results are clinically meaningful
Correct Answer: C. The findings are statistically significant
Explanation:
A p-value < 0.05 indicates statistical significance. It does not prove the null
hypothesis (A), nor indicate probability of correctness (B). Clinical significance
(D) must be assessed separately.
, Q5. A nurse evaluates research for applicability to practice. Which question best
reflects external validity?
A. Were participants randomly assigned?
B. Can findings be generalized to my patient population?
C. Was blinding used?
D. Were confounders controlled?
Correct Answer: B. Can findings be generalized to my patient
population?
Explanation:
External validity focuses on generalizability. Randomization (A), blinding
(C), and confounders (D) relate to internal validity.
Q6. A cohort study follows smokers and non-smokers over time. What type of
study design is this?
A. Experimental
B. Cross-sectional
C. Observational longitudinal
D. Case-control
Correct Answer: C. Observational longitudinal
Explanation:
Cohort studies are observational and follow participants over time. They are
not experimental (A), cross-sectional (B), or retrospective case-control (D).
Q7. Which bias occurs when participants drop out of a study at different rates
between groups?
A. Selection bias
B. Attrition bias
C. Recall bias
D. Observer bias
