Introduction:
This comprehensive practice examination is designed to assess the advanced knowledge of evidence-based practice
required for success in NR 504. It evaluates a candidate's ability to formulate clinical questions, search and
appraise the literature, and translate evidence into practice. The examination consists of 100 multiple-choice
questions, many of which are presented in a scenario-based format that tests critical thinking and clinical
reasoning. Emphasis is placed on the application of EBP principles to real-world clinical situations, overcoming
barriers to implementation, and evaluating outcomes to ensure the highest standards of advanced nursing
practice.
,SECTION ONE: QUESTIONS 1–100
1. A nurse practitioner is interested in implementing evidence-based practice in a primary care clinic. Which of
the following is the first step in the evidence-based practice process?
A. Appraise the evidence critically
B. Search for the best evidence
C. Formulate a clinical question
D. Evaluate the outcomes of the practice change
🟢 C. Formulate a clinical question
🔴 RATIONALE: The EBP process begins with the identification of a clinical problem and the formulation of a
well-structured clinical question, often using the PICO format. This question guides the subsequent search for
evidence.
2. A nurse is formulating a clinical question using the PICO format. Which of the following correctly identifies
the components of PICO?
A. Population, Intervention, Comparison, Outcome
B. Problem, Intervention, Control, Outcome
C. Population, Investigation, Comparison, Objective
D. Patient, Interest, Control, Outcome
🟢 A. Population, Intervention, Comparison, Outcome
,🔴 RATIONALE: PICO stands for Population, Intervention, Comparison, and Outcome. It is a widely used
framework for constructing clinical questions that guide evidence-based practice.
3. A nurse researcher is evaluating the hierarchy of evidence. Which of the following study designs provides the
highest level of evidence for a therapeutic intervention?
A. Systematic review and meta-analysis of randomized controlled trials
B. Randomized controlled trial
C. Cohort study
D. Case-control study
🟢 A. Systematic review and meta-analysis of randomized controlled trials
🔴 RATIONALE: Systematic reviews and meta-analyses of RCTs represent the highest level of evidence because
they synthesize results from multiple high-quality studies, providing a comprehensive and precise estimate of
the effect.
4. A nurse is searching for evidence to answer a clinical question. Which of the following databases is the most
comprehensive for nursing and allied health literature?
A. PubMed
B. CINAHL
C. PsycINFO
D. Cochrane Library
🟢 B. CINAHL
, 🔴 RATIONALE: CINAHL (Cumulative Index to Nursing and Allied Health Literature) is the most comprehensive
database for nursing and allied health literature, indexing thousands of journals, books, and dissertations in the
field.
5. A nurse is appraising a research article and notes that the study has a large sample size. Which of the
following is the most important advantage of a large sample size?
A. It reduces measurement error
B. It increases the precision of the estimate
C. It eliminates the need for randomization
D. It ensures the study is valid
🟢 B. It increases the precision of the estimate
🔴 RATIONALE: A larger sample size generally increases the statistical power and precision of the study's
estimates, reducing the margin of error and increasing confidence in the findings.
6. A nurse practitioner is implementing a new fall prevention protocol based on evidence from a clinical practice
guideline. Which of the following is the most important characteristic of a high-quality clinical practice
guideline?
A. It is published in a peer-reviewed journal
B. It is developed by a single expert
C. It is based on a systematic review of the evidence and includes recommendations
D. It includes a clear marketing plan
🟢 C. It is based on a systematic review of the evidence and includes recommendations
