MULTIPLE CHOICE
1. Evidence-based practice is an approach to clinical decision-making that is based on:
a. the most current material from textbooks.
b. methodically conducted research studies.
c. established clinical traditions.
d. data from quality improvement and risk management.
RIGHT CHOICE ✔✔ B
The highest quality evidence comes from rigorously designed research studies published in scholarly journals.
Textbook content often becomes outdated by the time it is published. Many healthcare environments lack systems
to help staff integrate new evidence, and nurses often rely on tradition or convenience when risk-management data
is not readily available. Though quality improvement and risk-management data are valuable, they are not always
research-based; relying on high-quality research is essential.
2. When evidence-based practice is applied, patient care will be:
a. uniform for everyone.
b. without regard to patient culture.
c. adapted to individual situations.
d. free from the need for critical thinking.
RIGHT CHOICE ✔✔ C
Incorporating clinical expertise along with patients' cultural values and preferences ensures that evidence is used
appropriately and ethically. Even with the best available evidence, care and outcomes will vary. Nurses must
develop critical thinking to determine the relevance and appropriateness of the evidence.
3. In a PICOT question, which letter corresponds to the current standard of care?
a. P.
b. I.
c. C.
d. O.
RIGHT CHOICE ✔✔ C
C = Comparison of interest — the current standard or intervention typically used.
P = Patient population of interest — defined by characteristics such as age, gender, ethnicity, disease, or health
, condition.
I = Intervention of interest — the treatment or diagnostic tool being considered.
O = Outcome — the desired result or effect of the intervention.
4. Creating a well-structured PICOT question helps the nurse to:
a. locate relevant evidence.
b. include all five elements in order.
c. retrieve the greatest number of articles.
d. accept routine clinical practices.
RIGHT CHOICE ✔✔ A
A focused question simplifies the search for relevant evidence in the literature. A PICOT question does not need to
include all five elements nor follow a strict sequence. Nurses should question routine practices and use critical
thinking to improve care.
5. If a nurse wants to quickly review existing research on a topic, which resource would be most helpful?
a. CINAHL
b. PubMed
c. MEDLINE
d. The Cochrane Database
RIGHT CHOICE ✔✔ D
The Cochrane Database of Systematic Reviews provides synthesized, pre-appraised evidence through full-text
systematic reviews. Though MEDLINE, PubMed, and CINAHL are also comprehensive databases, Cochrane is
ideal for quickly finding summarized research.
6. To develop a care plan for a patient with specific needs, the nurse should consult:
a. The Cochrane Database.
b. MEDLINE.
c. NGC.
d. CINAHL.
RIGHT CHOICE ✔✔ C
The National Guidelines Clearinghouse (NGC) offers clinical practice guidelines — systematically developed
recommendations for care in specific patient situations. It is a key resource for developing patient care plans.
, 7. After finding 25 articles from a literature search, what should the nurse examine first to select the most relevant
ones?
a. Abstracts.
b. Literature reviews.
c. Methods sections.
d. Narrative sections.
RIGHT CHOICE ✔✔ A
An abstract provides a concise summary indicating whether an article is research-based or clinical and highlights
the purpose, findings, and implications for practice — making it the best starting point.
8. To explore how attending a cardiac rehabilitation program affects post-myocardial infarction depression, the ideal
study type would be a:
a. randomized controlled trial.
b. qualitative study.
c. case control study.
d. descriptive study.
RIGHT CHOICE ✔✔ B
Qualitative studies explore individuals' experiences within health-related contexts — making this approach
suitable for examining program effectiveness from the patient's perspective.
9. Six months after implementing an early mobility protocol, a hospital sees reduced DVT rates. This is an example
of which EBP step?
a. Formulating a clinical question.
b. Applying the evidence.
c. Evaluating the practice change.
d. Reporting the results.
RIGHT CHOICE ✔✔ C
After implementing changes, the next step is to assess their impact by analyzing outcomes data — determining
whether improvements occurred.
MULTIPLE RESPONSE
1. Using evidence-based practice involves gathering the most relevant evidence and critically appraising it. It also
