Section 1: Quality Improvement & Performance
Management (35 questions)
1. Which quality improvement model uses the Plan-Do-Study-Act cycle for iterative testing
of change?
A) Six Sigma
B) PDSA Cycle (correct answer)
C) Lean Management
D) Baldrige Framework
Rationale: The PDSA cycle, developed by Walter Shewhart and popularized by W. Edwards
Deming, is an iterative four-step model for testing changes in real work settings on a small scale
before full implementation. Six Sigma focuses on reducing variation using DMAIC
methodology, Lean focuses on eliminating waste, and the Baldrige Framework is a broader
organizational excellence model rather than a specific improvement cycle.
2. In Lean methodology, what term describes any activity that consumes resources without
adding value for the customer?
A) Kaizen
B) Gemba
C) Muda/Waste (correct answer)
, D) Kanban
Rationale: Muda is the Japanese term for waste in Lean methodology, referring to activities that
consume resources but do not add value from the customer's perspective. Kaizen refers to
continuous improvement, Gemba refers to the actual place where work happens, and Kanban is a
visual scheduling system.
3. Which of the following best describes a "never event" in healthcare quality?
A) A rare but acceptable complication
B) A serious, largely preventable adverse event that should never occur (correct
answer)
C) An event requiring only internal reporting
D) A billing discrepancy
Rationale: Never events, as defined by the National Quality Forum, are serious and largely
preventable patient safety incidents such as wrong-site surgery or retained surgical items. These
are distinguished from routine complications because appropriate systems and processes should
prevent their occurrence entirely.
4. What is the primary purpose of a root cause analysis (RCA) following a sentinel event?
A) To assign blame to individual staff members
B) To identify underlying systemic causes and prevent recurrence (correct answer)
C) To satisfy legal documentation requirements only
D) To calculate financial losses
Rationale: RCA is a structured method for identifying the underlying systemic and process-
related causes of an adverse event, moving beyond individual blame to understand how
organizational systems contributed to the failure, with the ultimate goal of implementing
corrective actions that prevent recurrence.
5. Which accrediting body sets standards and performs on-site surveys for hospital
accreditation in the United States?
, A) CDC
B) The Joint Commission (correct answer)
C) HHS
D) OSHA
Rationale: The Joint Commission is the primary accrediting body that evaluates and accredits
U.S. healthcare organizations against established quality and safety standards through on-site
surveys, and accreditation is often linked to Medicare/Medicaid reimbursement eligibility.
6. In a control chart used for statistical process control, what does a data point outside the
upper or lower control limits typically indicate?
A) Normal common-cause variation
B) Special-cause variation requiring investigation (correct answer)
C) A data entry error only
D) The process is in perfect control
Rationale: Control limits, typically set at three standard deviations from the mean, distinguish
common-cause (expected) variation from special-cause variation. A point outside these limits
signals an unusual occurrence that warrants investigation to identify and address its specific
cause.
7. What does the acronym HCAHPS stand for in the context of hospital quality
measurement?
A) Healthcare Cost and Hospital Payment System
B) Hospital Consumer Assessment of Healthcare Providers and Systems (correct
answer)
C) Health Coverage and Hospital Patient Safety
D) Hospital Clinical Accreditation and Health Performance Standards
, Rationale: HCAHPS is a standardized survey instrument used to measure patients' perspectives
on hospital care, and its results are publicly reported and tied to value-based purchasing
reimbursement programs administered by CMS.
8. Which of the following is a key characteristic of a "high reliability organization" in
healthcare?
A) Zero tolerance for reporting errors
B) Preoccupation with failure and sensitivity to operations (correct answer)
C) Strict hierarchical decision-making only
D) Minimal staff training requirements
Rationale: High reliability organizations are characterized by a preoccupation with failure
(treating near misses as information), reluctance to simplify interpretations, sensitivity to
operations, commitment to resilience, and deference to expertise — all aimed at consistently
avoiding catastrophic errors in complex, high-risk environments.
9. What is benchmarking in healthcare quality management?
A) Setting arbitrary internal targets
B) Comparing organizational performance against best practices or industry
standards (correct answer)
C) A one-time compliance audit
D) A financial forecasting technique
Rationale: Benchmarking involves systematically comparing an organization's processes and
performance metrics to those of high-performing peers or industry standards to identify
performance gaps and drive targeted improvement efforts.
10. Which quality dimension refers to providing care that does not vary in quality based on
personal characteristics such as gender, ethnicity, or socioeconomic status?
A) Timeliness
B) Efficiency
