INTRO TO NURSING RESEARCH AND EVIDENCE-BASED PRACTICE EBP 205 QUESTIONS AND CORRECT ANSWERS 2025-2026
A nursing student is taking care of a patient with possible appendicitis and is
curious about the best method of diagnosing this disorder. What does the nursing
student have to consider in formulating a question using the PICO format (patient,
population, or problem; intervention; comparison intervention; outcomes) to
determine evidence-based practice?
a. Problem: appendicitis; interventions: ultrasound versus CT scan; outcome:
diagnosis of appendicitis
b. Problem: pain; interventions: meperidine versus morphine; outcome: pain free
c. Problem: fever; interventions: cooling measures versus antipyretics; outcome:
normal temperature
d. Problem: appendicitis; Interventions: complete blood count versus chemistry
panel tests; outcome: painless.
d. Problem: appendicitis; Interventions: complete blood count versus chemistry
panel tests; outcome: painless
The PICO format asks for the patient's problem, the two possible interventions for
comparison (i.e., diagnostics), and the desired outcome from the interventions.
The nurse decides to access a systematic review database to determine evidencebased practice related to the patient's treatment plan for a diagnosis of otitis media
(i.e., ear infection). What database can provide that type of resource?
a. Cumulative Index of Nursing and Allied Health Literature (CINAHL)
b. Cochrane
c. PubMed
d. MD Consult
b. Cochrane
The Cochrane database provides systematic reviews of the literature. CINAHL and
PubMed provide primary research articles, and MD Consult provides background
information.
