EBP 205 INTRO TO NURSING RESEARCH AND EVIDENCE-BASED PRACTICE QUESTIONS AND CORRECT ANSWERS LATEST UPDATE

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
evidence-based 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.
The nurse researcher provides participants with informed consent so that what
ethical principle is upheld?
a. Respect for persons
b. Beneficence
c. Justice
d. Ethics
a. Respect for persons
Informed consent abides by the principle of respect for persons. The beneficence
principle reminds researchers to minimize harms and maximize benefits. The principle
of justice requires researchers to treat people fairly and to design research to select
subjects equitably and avoid exploitation of vulnerable populations. Ethics is a general
concept, not a specific principle.
The nurse feels that the results of a recent literature search and analysis about
handwashing should be implemented in the entire hospital system. With whom
would the nurse be required to collaborate?
a. Colleagues caring for patients in her unit
b. Colleagues in the community
c. Administrators at the hospital
d. Others in her department
c. Administrators at the hospital
