NSG 6020 Application of Evidence for Quality and Safety Final
Exam | Complete Practice Questions, Answers & Detailed
Rationales 2026/2027
Question 1
A nurse leader is formulating a clinical question using the PICOT format
to investigate whether bedside shift reporting reduces patient falls
compared to traditional nurse's station reporting. What does the "T"
component represent in this framework?
• A. Target population
• B. Timeframe for the intervention to achieve the desired outcome
• C. Testing methodology used in the study
• D. Type of statistical analysis required
Correct Answer: B. Timeframe for the intervention to achieve the
desired outcome.
Detailed Rationale: In the PICOT format (Population, Intervention,
Comparison, Outcome, Timeframe), the "T" specifies the time it takes
for the intervention to achieve the outcome (e.g., over a 6-month
period).
Question 2
When appraising the hierarchy of evidence for a clinical practice
change, which of the following study designs sits at the apex of the
traditional evidence hierarchy?
• A. Single randomized controlled trial (RCT)
, • B. Cohort study
• C. Systematic review or meta-analysis of randomized controlled
trials
• D. Expert committee consensus report
Correct Answer: C. Systematic review or meta-analysis of randomized
controlled trials.
Detailed Rationale: Systematic reviews and meta-analyses of multiple
randomized controlled trials synthesize the highest level of rigorous
empirical evidence, minimizing bias and providing the most reliable
basis for clinical decision-making.
Question 3
A quality improvement team wants to test a rapid change to medication
reconciliation workflows. Which quality improvement framework
utilizes the Plan-Do-Study-Act (PDSA) cycle for rapid-cycle testing?
• A. Six Sigma (DMAIC)
• B. Model for Improvement
• C. Failure Mode and Effects Analysis (FMEA)
• D. Root Cause Analysis (RCA)
Correct Answer: B. Model for Improvement.
Detailed Rationale: The Model for Improvement, developed by
Associates in Process Improvement, uses the PDSA cycle as a framework
for testing small-scale changes quickly to determine if they lead to
improvement.
Question 4
,Following a serious medication error, a hospital forms an
interprofessional team to investigate the underlying system failures
rather than focusing on individual human error. Which analytical tool
should the team use retrospectively to identify root causes?
• A. Failure Mode and Effects Analysis (FMEA)
• B. Root Cause Analysis (RCA)
• C. Plan-Do-Study-Act (PDSA) cycle
• D. Cost-benefit analysis
Correct Answer: B. Root Cause Analysis (RCA).
Detailed Rationale: Root Cause Analysis (RCA) is a structured
retrospective tool used to analyze sentinel events and major errors to
identify underlying system and process vulnerabilities rather than
assigning individual blame.
Question 5
An advanced practice nurse is designing a prospective, proactive risk
assessment to evaluate a newly proposed electronic health record
(EHR) medication-ordering module before implementation. Which tool
is best suited for this purpose?
• A. Root Cause Analysis (RCA)
• B. Failure Mode and Effects Analysis (FMEA)
• C. SWOT analysis
• D. Randomized controlled trial
Correct Answer: B. Failure Mode and Effects Analysis (FMEA).
, Detailed Rationale: FMEA is a prospective, proactive quality tool used
to examine processes before implementation to identify where and
how a process might fail and to assess the relative impact of different
failures.
Question 6
According to the Donabedian model for evaluating healthcare quality,
which of the following measures represents an evaluation of
"Structure"?
• A. Hospital 30-day readmission rate for heart failure
• B. Patient satisfaction scores regarding nurse communication
• C. Ratio of registered nurses to patients on a medical unit
• D. Percentage of patients who receive prophylactic antibiotics
prior to surgery
Correct Answer: C. Ratio of registered nurses to patients on a medical
unit.
Detailed Rationale: The Donabedian model categorizes quality
measures into Structure (the attributes of the settings where care
occurs, such as staffing ratios, equipment, and facilities), Process (how
care is provided), and Outcome (the effects of care on health status).
Question 7
A nurse manager aims to foster a "Just Culture" unit environment.
Which behavior exemplifies a Just Culture approach when an error
occurs?
