SECTION 1: EVIDENCE-BASED PRACTICE AND RESEARCH UTILIZATION Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A nurse manager on a busy medical-surgical unit notices that catheter-associated
urinary tract infection rates have risen over the past quarter. She convenes a small team
to review the problem and wants to search the literature efficiently. Before beginning the
search, the team should first develop a structured question that identifies the
population, intervention, comparison, outcome, and time frame.
A. Formulate a PICOT question ✓ CORRECT
B. Implement a protocol change immediately
C. Evaluate patient outcomes from the previous year
D. Search for systematic reviews using broad terms
Correct Answer: A
,Rationale: Formulating a PICOT question is the foundational first step in evidence-based
practice because it creates a focused, searchable query that keeps the team aligned
and prevents wasted effort. Searching with broad terms or implementing changes
before defining the question leads to irrelevant evidence and premature action. Starting
with a clear question saves time and ensures the evidence gathered directly addresses
the clinical problem.
Question 2 of 50
A staff nurse is reading a clinical practice guideline about pressure injury prevention.
The guideline recommends a specific repositioning schedule based on findings from
multiple studies that randomly assigned patients to different turning frequencies and
measured outcomes blindly.
A. Case-control study
B. Cohort study
C. Randomized controlled trial ✓ CORRECT
D. Cross-sectional survey
Correct Answer: C
Rationale: Randomized controlled trials are considered high-level evidence because
randomization minimizes selection bias and confounding variables, allowing causal
inferences about interventions. Cohort and case-control studies are observational and
more susceptible to bias, while cross-sectional surveys capture data at a single point in
time without intervention. In most evidence hierarchies, systematic reviews of RCTs sit
at the top, followed by individual RCTs.
Question 3 of 50
A nurse is trying to convince the unit council to adopt a new evidence-based wound care
protocol. The council asks for a structured framework to guide the decision-making
process and ensure the change is evaluated properly.
, A. Iowa Model ✓ CORRECT
B. Orem's Self-Care Model
C. Roy Adaptation Model
D. Neuman Systems Model
Correct Answer: A
Rationale: The Iowa Model is a widely used evidence-based practice framework
specifically designed to guide clinical decision-making and protocol changes in
healthcare settings. Orem's, Roy's, and Neuman's models are nursing theories focused
on patient care delivery rather than the systematic process of integrating research into
practice. Using the Iowa Model helps teams identify triggers, form teams, and evaluate
outcomes systematically.
Question 4 of 50
A nurse finds two primary studies on hand hygiene compliance that report conflicting
results about the effectiveness of alcohol-based gel versus soap and water. To resolve
the uncertainty and make a clinical recommendation, the nurse should look for the
strongest synthesis of available evidence.
A. Single-center observational study
B. Meta-analysis of randomized controlled trials ✓ CORRECT
C. Narrative literature review
D. Pilot feasibility study
Correct Answer: B
Rationale: A meta-analysis statistically pools data from multiple randomized controlled
trials to provide the most precise estimate of an intervention's effect, making it the
strongest evidence when primary studies conflict. Single observational studies and
narrative reviews lack the statistical rigor to resolve conflicting findings, and pilot
studies are underpowered for definitive conclusions. When studies disagree, clinicians
should look for the highest-quality synthesis available.
