NURS 4100 WEEK 1: QUALITY AND
SAFETY THROUGH EVIDENCE-BASED
PRACTICE
1. What is the primary goal of Evidence-Based Practice (EBP) in the clinical setting?
A. To improve patient outcomes through the integration of best evidence, clinical expertise,
and patient values
B. To ensure that clinicians follow traditional hospital policies
C. To increase the volume of published nursing research
D. To reduce the educational requirements for registered nurses
Answer: A
Conceptual Explanation: EBP is defined by the integration of clinical expertise, patient
values/preferences, and the best research evidence to improve clinical outcomes.
2. Which of the following represents the highest level of evidence in the evidence hierarchy?
A. A single randomized controlled trial (RCT)
B. Opinions of authorities and/or reports of expert committees
C. Well-designed case-control and cohort studies
,D. Systematic review or meta-analysis of all relevant RCTs
Answer: D
Conceptual Explanation: Level I evidence consists of systematic reviews or meta-analyses
of all relevant randomized controlled trials (RCTs), which synthesize findings across
multiple studies.
3. In the PICOT format, what does the ‘I’ represent?
A. Implementation
B. Intervention or issue of interest
C. Investigation
D. Integration
Answer: B
Conceptual Explanation: PICOT stands for Population (P), Intervention (I), Comparison
(C), Outcome (O), and Time (T).
4. Which component of PICOT is often optional but adds specificity to the clinical question?
A. Time
B. Outcome
C. Population
D. Intervention
, Answer: A
Conceptual Explanation: While P, I, and O are essential, the Time (T) and Comparison (C)
components may not always be applicable depending on the clinical query.
5. What is ‘Step Zero’ in the EBP process?
A. Asking the clinical question
B. Searching for the best evidence
C. Cultivating a spirit of inquiry
D. Critically appraising the evidence
Answer: C
Conceptual Explanation: Before asking a question, clinicians must have a spirit of
inquiry—a curiosity about how to provide the best care and a drive to challenge the status
quo.
6. Which of the following is considered internal evidence?
A. A peer-reviewed journal article
B. A textbook on pathophysiology
C. Clinical practice guidelines from a national organization
D. Data from a hospital’s quality improvement project
Answer: D
