1. What is the first step in the evidence-based practice (EBP) process?
a. Appraising the evidence
b. Asking a clinical question
c. Implementing the intervention
d. Evaluating outcomes
b. Asking a clinical question
The EBP process begins with formulating a well-structured clinical question, often
using the PICOT format.
2. In the PICOT framework, the “C” typically stands for:
a. Criteria
b. Comparison
c. Context
d. Conclusion
b. Comparison
PICOT stands for Population, Intervention, Comparison, Outcome, and Time. “C”
represents the comparison intervention or control group.
3. Which type of research design provides the strongest level of evidence?
a. Case study
b. Randomized controlled trial (RCT)
c. Cohort study
d. Expert opinion
b. Randomized controlled trial (RCT)
, RCTs minimize bias and establish cause-and-effect relationships, making them the
gold standard in research designs.
4. A systematic review differs from a literature review because it:
a. Focuses on one author’s perspective
b. Uses a structured and replicable methodology
c. Relies on expert opinion only
d. Is not peer-reviewed
b. Uses a structured and replicable methodology
Systematic reviews follow strict guidelines to synthesize research evidence, reducing
bias compared to narrative reviews.
5. Which database is most commonly used for nursing evidence-based practice?
a. LexisNexis
b. CINAHL
c. JSTOR
d. ERIC
b. CINAHL
CINAHL (Cumulative Index to Nursing and Allied Health Literature) is a primary

6. What is the main purpose of a meta-analysis?
a. To collect expert opinions
b. To combine statistical data from multiple studies
c. To summarize qualitative findings
d. To critique one study
b. To combine statistical data from multiple studies
A meta-analysis increases statistical power by pooling quantitative results from
multiple studies.
7. Which type of study is most appropriate for exploring patient experiences?
a. Randomized controlled trial
b. Case-control study
c. Qualitative research
d. Cohort study
c. Qualitative research
Qualitative research focuses on meanings, experiences, and perspectives, making it
ideal for patient-centered inquiry.
8. When critically appraising a study, internal validity refers to:
a. Generalizability of results
b. Accuracy of study findings within the study design
c. Applicability to practice settings
, d. Relevance to patient populations
b. Accuracy of study findings within the study design
Internal validity assesses whether the results are trustworthy and not influenced by
bias or confounding variables.
9. In EBP, external validity refers to:
a. Whether the study is free of bias
b. Applicability of results to real-world settings
c. Randomization methods
d. Statistical significance
b. Applicability of results to real-world settings
External validity relates to generalizability and transferability of findings beyond the
study population.
10. Which type of bias occurs when participants drop out of a study?
a. Selection bias
b. Attrition bias
c. Recall bias
d. Publication bias
b. Attrition bias
Attrition bias occurs when participant loss affects group comparability and study
results.
11. Which level of evidence is considered the lowest in the hierarchy?
a. Randomized controlled trial
b. Systematic review
c. Expert opinion
d. Cohort study
c. Expert opinion
Expert opinion is considered the lowest level because it lacks systematic data and is
subject to personal bias.
12. The “P” in a PICOT question stands for:
a. Practice guideline
b. Population
c. Problem
d. Probability
b. Population
“P” defines the patient group or population to whom the intervention or exposure will
be applied.
13. What is the primary goal of evidence-based practice?
a. Reduce healthcare costs
