1. A resident notices that postoperative infections have increased
over the past 6 months. What is the most appropriate first step in
a quality improvement (QI) project?
A. Implement a new antibiotic protocol immediately
B. Collect and analyze baseline infection data
C. Discipline the surgical staff
D. Notify the media
Correct Answer: B. Collect and analyze baseline infection data
Rationale: Every quality improvement initiative begins by understanding
the current process through reliable baseline data. Identifying the
magnitude of the problem, trends, and contributing factors allows
targeted interventions. Implementing changes before understanding the
root causes may waste resources and fail to improve patient outcomes.
2. Which quality improvement model is based on repeated cycles of
planning, implementing, studying results, and acting on findings?
,A. Fishbone Analysis
B. Six Sigma
C. Plan-Do-Study-Act (PDSA)
D. Root Cause Analysis
Correct Answer: C. Plan-Do-Study-Act (PDSA)
Rationale: The PDSA cycle is the cornerstone of continuous quality
improvement. It emphasizes small-scale testing of interventions
followed by evaluation and refinement before widespread
implementation. This iterative process promotes sustainable
improvements in healthcare delivery.
3. Which measure best represents a process measure rather than an
outcome measure?
A. Thirty-day mortality rate
B. Hospital readmission rate
C. Percentage of patients receiving antibiotics within one hour before
surgery
D. Patient survival after myocardial infarction
Correct Answer: C. Percentage of patients receiving antibiotics within
one hour before surgery
Rationale: Process measures evaluate whether recommended
healthcare activities are performed correctly. Outcome measures assess
the final health status of patients, whereas process measures help
determine whether evidence-based practices are consistently followed.
, 4. Root cause analysis is primarily used to:
A. Assign blame to healthcare workers
B. Estimate healthcare costs
C. Identify system factors contributing to adverse events
D. Predict hospital revenue
Correct Answer: C. Identify system factors contributing to adverse
events
Rationale: Root cause analysis focuses on identifying underlying system
failures rather than individual mistakes. The goal is to improve
healthcare systems by addressing contributing factors that increase the
likelihood of future adverse events.
5. Which statement best describes evidence-based medicine?
A. Following expert opinion only
B. Using only randomized controlled trials
C. Integrating best available evidence, clinical expertise, and patient
preferences
D. Following hospital policy exclusively
Correct Answer: C. Integrating best available evidence, clinical
expertise, and patient preferences
Rationale: Evidence-based medicine requires combining high-quality
scientific evidence with physician experience and individual patient
, values. All three components are essential for optimal patient-centered
decision-making.
6. A physician reviews recent literature before changing
management recommendations for hypertension. This
demonstrates:
A. Defensive medicine
B. Practice-based learning
C. Billing optimization
D. Population health management
Correct Answer: B. Practice-based learning
Rationale: Practice-based learning involves evaluating one's clinical
practice, incorporating new evidence, and continuously improving
patient care through lifelong learning.
7. Which study design provides the highest level of evidence for
evaluating therapy?
A. Case report
B. Cross-sectional study
C. Cohort study
D. Systematic review and meta-analysis of randomized controlled
trials
