2026/2027 Q&A | Instant Download Pdf
1. Which methodology is most commonly used for
continuous quality improvement in healthcare?
A. Six Sigma
B. Root Cause Analysis
C. Plan-Do-Study-Act
D. Failure Mode and Effects Analysis
Answer: C. Plan-Do-Study-Act
Rationale: PDSA cycles are iterative and designed for testing
and implementing small changes in healthcare processes.
2. The primary goal of quality improvement is to:
A. Reduce staffing costs
B. Improve patient outcomes and system performance
C. Eliminate all errors
D. Meet accreditation requirements only
Answer: B. Improve patient outcomes and system
performance
Rationale: QI focuses on better outcomes, safety, and
efficiency rather than cost-cutting alone.
, 3. Which organization developed the Six Aims for
Improvement?
A. CDC
B. WHO
C. Institute of Medicine
D. Joint Commission
Answer: C. Institute of Medicine
Rationale: The IOM outlined care as safe, effective, patient-
centered, timely, efficient, and equitable.
4. Which tool is best for identifying the root causes of an
adverse event?
A. Control chart
B. Flowchart
C. Root Cause Analysis
D. Histogram
Answer: C. Root Cause Analysis
Rationale: RCA systematically identifies underlying system
failures contributing to events.
5. A process that performs consistently but produces poor
outcomes is described as:
A. Unstable
B. Inefficient
, C. Defective
D. Reliable
Answer: C. Defective
Rationale: A stable but poorly designed process will reliably
produce poor results.
6. Which measure reflects the impact of care on patients?
A. Process measure
B. Structural measure
C. Outcome measure
D. Balancing measure
Answer: C. Outcome measure
Rationale: Outcome measures assess the results of
healthcare on patient health.
7. Balancing measures are used to:
A. Track financial performance
B. Identify unintended consequences
C. Measure staff satisfaction only
D. Replace outcome measures
Answer: B. Identify unintended consequences
Rationale: Balancing measures ensure improvements in one
area do not cause harm in another.
, 8. Which chart is most useful for tracking variation over
time?
A. Pie chart
B. Histogram
C. Scatter plot
D. Control chart
Answer: D. Control chart
Rationale: Control charts distinguish common cause from
special cause variation.
9. Common cause variation is best described as:
A. Unexpected and rare
B. Due to system design
C. Caused by human error
D. Easily eliminated
Answer: B. Due to system design
Rationale: Common cause variation is inherent to the
process itself.
10. Which QI model emphasizes defect reduction and
statistical analysis?
A. PDSA
B. Lean
C. Six Sigma
D. RCA
