### Section 1: Foundations of Evidence-Based Practice (Questions 1-20)
**1.** What is the first step in the Evidence-Based Practice (EBP) process?
A) Appraising the evidence
B) Formulating a clinical question
C) Implementing a change in practice
D) Searching the literature
**Correct Answer: B**
*Rationale: The EBP process begins with formulating an answerable clinical question, often
using the PICOT format. Without a clear question, searching and appraising evidence lacks
direction.*
**2.** In the PICOT framework, what does "I" stand for?
A) Interpretation

B) Intervention
C) Investigation
D) Implementation
**Correct Answer: B**
*Rationale: P = Patient/Population, I = Intervention, C = Comparison, O = Outcome, T = Time.
The intervention is the primary treatment or exposure being considered.*
**3.** Which study design provides the highest level of evidence for therapy questions?
A) Case-control study
B) Systematic review of randomized controlled trials (RCTs)
C) Cohort study
D) Expert opinion
**Correct Answer: B**
*Rationale: Systematic reviews and meta-analyses of RCTs sit at the top of evidence hierarchies
because they synthesize multiple high-quality studies, minimizing bias.*
**4.** A nurse asks: "In adults with type 2 diabetes, does daily self-monitoring of blood glucose
compared to no monitoring improve HbA1c levels at 6 months?" What is the "C" in this PICOT?
A) Adults with type 2 diabetes
B) Daily self-monitoring
C) No monitoring
D) HbA1c levels
**Correct Answer: C**

*Rationale: The comparison group is the alternative to the intervention. Here, no monitoring is
compared to daily self-monitoring.*
**5.** Which database is most specific for nursing and allied health literature?
A) PubMed
B) CINAHL
C) Google Scholar
D) Cochrane Library
**Correct Answer: B**
*Rationale: CINAHL (Cumulative Index to Nursing and Allied Health Literature) indexes nursing
journals, while PubMed is broader (biomedical). Cochrane focuses on systematic reviews.*
**6.** A meta-analysis differs from a systematic review because it:
A) Includes only qualitative studies
B) Statistically combines results of multiple studies
C) Does not require a literature search
D) Is written by a single author
**Correct Answer: B**
*Rationale: A meta-analysis uses statistical techniques to pool data from multiple studies,
increasing power and precision. A systematic review may or may not include meta-analysis.*
**7.** Which of the following is a primary source in EBP?
A) A textbook chapter on heart failure
B) A clinical practice guideline

C) An original RCT published in a journal
D) A narrative review article
**Correct Answer: C**
*Rationale: Primary sources are original research studies written by those who conducted the
research. RCTs, cohort studies, and case series are primary.*
**8.** What is the purpose of a literature review in EBP?
A) To prove the nurse's hypothesis
B) To identify existing evidence and gaps
C) To replace clinical expertise
D) To avoid using patient preferences
**Correct Answer: B**
*Rationale: A literature review identifies what is known and unknown about a topic, helping to
frame evidence-based changes and avoid duplicating efforts.*
**9.** Which of the following is a well-built clinical question for a therapy?
A) "What is the best treatment for pneumonia?"
B) "In hospitalized adults with CAP, does azithromycin compared to amoxicillin reduce 30-day
mortality?"
C) "How does azithromycin work?"
D) "Why do doctors prescribe azithromycin for pneumonia?"
**Correct Answer: B**
*Rationale: This question includes P (hospitalized adults with CAP), I (azithromycin), C
(amoxicillin), O (30-day mortality). It is specific and answerable.*
