1. What is the primary goal of evidence-based practice (EBP) in nursing?
a. To reduce patient complaints
b. To improve patient outcomes
c. To increase nurse autonomy
d. To lower healthcare costs
EBP aims to integrate the best research evidence with clinical
expertise and patient values to improve outcomes.
2. Which of the following best defines a PICOT question?
a. A type of nursing diagnosis
b. A medication administration protocol
c. A framework for developing clinical questions
d. A patient care checklist
PICOT helps structure a searchable clinical question: Patient,
Intervention, Comparison, Outcome, and Time.
3. In the PICOT format, what does the "I" stand for?
a. Investigation
, b. Intervention
c. Interaction
d. Institution
"I" stands for Intervention or exposure of interest in the clinical
question.
4. What type of research is considered the strongest level of evidence?
a. Expert opinion
b. Case-control study
c. Systematic review and meta-analysis
d. Qualitative research
Systematic reviews and meta-analyses synthesize results from
multiple studies, making them high-quality evidence.
5. A nurse wants to know the best intervention for reducing falls in elderly
patients. What is the best first step?
a. Formulate a PICOT question
b. Conduct a randomized trial
c. Ask a colleague for advice
d. Check the hospital policy manual
Formulating a PICOT question provides direction for evidence
searching and evaluation.
6. Which database is most commonly used for nursing evidence-based
literature?
a. JSTOR
b. WebMD
, c. CINAHL
d. Google Scholar
CINAHL (Cumulative Index to Nursing and Allied Health Literature)
is the premier source for nursing literature.
7. What is the benefit of a randomized controlled trial (RCT)?
a. It provides expert opinion
b. It is quick to conduct
c. It reduces bias by randomly assigning subjects
d. It allows patients to choose their treatment
RCTs are considered gold standard for clinical trials because they
minimize bias and confounding.
8. Which part of a research article explains how data was collected and
analyzed?
a. Introduction
b. Methods
c. Results
d. Discussion
The Methods section describes study design, sample, data
collection, and analysis.
9. What does "peer-reviewed" mean?
a. Written by a nurse
b. Evaluated by experts before publication
c. Published by a hospital
d. Posted on social media
, Peer review ensures credibility and academic rigor in published
research.
10.What is the nurse's role in evidence-based practice?
a. Conducting all research
b. Writing hospital policies
c. Integrating evidence into patient care
d. Replacing physician decisions
Nurses are expected to apply research evidence to inform their
clinical decision-making.
11.Which of the following is an example of qualitative research?
a. A trial comparing two drugs
b. A study exploring patient experiences with chemotherapy
c. A cohort study on infection rates
d. A lab experiment on drug metabolism
Qualitative research explores meanings and experiences, often
using interviews or focus groups.
12.What is a barrier to implementing EBP in the clinical setting?
a. Lack of time and resources
b. Too much patient input
c. Too many RCTs available
d. Excess nurse autonomy
Common barriers include time constraints, limited access to
resources, and insufficient training.
