Section 1: Quality Improvement & Patient Safety (Questions 1-
10)
Q1. A hospital unit experienced three medication administration errors involving
insulin dosing within one month. The nurse manager convenes a team to analyze the
issue using a systematic approach that cycles through planning, testing changes, and
evaluating results. Which quality improvement model is being implemented?
A. Root Cause Analysis (RCA)
B. Failure Mode and Effects Analysis (FMEA)
C. Plan-Do-Study-Act (PDSA) [CORRECT]
D. Six Sigma DMAIC
Rationale: PDSA is a cyclical model specifically designed for testing and refining
changes in real-world settings through iterative planning, implementation, study, and
action phases. RCA (Option A) is retrospective and focused on identifying underlying
causes of sentinel events, not iterative testing. FMEA (Option B) is prospective and
used to identify potential failures before they occur. Six Sigma DMAIC (Option D) is a
data-driven methodology for eliminating defects, not the cyclical testing model
described.
Correct Answer: C
Q2. A patient received a 10-fold overdose of heparin due to a pharmacy dispensing
error and subsequently experienced a major bleeding event requiring transfusion.
According to The Joint Commission definitions, this event should be classified as:
,A. A near-miss event requiring no further action
B. A sentinel event requiring immediate root cause analysis and reporting
[CORRECT]
C. An expected outcome given the patient's anticoagulation therapy
D. A minor incident suitable for unit-level documentation only
Rationale: A sentinel event is defined as an unexpected occurrence involving death
or serious physical or psychological injury, or the risk thereof, including major
permanent loss of function or severe temporary harm requiring intervention. A 10-
fold heparin overdose with major bleeding meets this definition and requires RCA.
Option A is incorrect as a near-miss would be the error caught before reaching the
patient. Option C is dangerously wrong—medication errors are never expected
outcomes. Option D understates the severity and reporting requirements.
Correct Answer: B
Q3. During a root cause analysis of a patient fall resulting in a hip fracture, the team
identifies that the bed alarm was not activated because the UAP assumed the RN had
done so during shift handoff. Which contributing factor category BEST describes this
failure?
A. Equipment malfunction
B. Communication breakdown during care transitions [CORRECT]
C. Inadequate staffing ratios
D. Patient noncompliance with safety protocols
Rationale: The failure occurred during shift handoff when critical safety information
(bed alarm status) was not clearly communicated between the outgoing RN and the
UAP, representing a breakdown in care transition communication. Option A is
incorrect as the equipment functioned properly but was not activated. Option C is
not supported by the scenario. Option D inappropriately blames the patient for a
system failure.
Correct Answer: B
, Q4. A nurse manager is implementing a Just Culture framework after a medication
error. A staff nurse administered the wrong medication because she misread a look-
alike drug label while working a double shift. Under Just Culture principles, how
should this be addressed?
A. Terminate the nurse immediately for incompetence
B. Report the nurse to the state board of nursing for disciplinary action
C. Analyze system factors (fatigue, labeling, staffing) and provide coaching while
addressing contributory system failures [CORRECT]
D. Ignore the error since the patient suffered no harm
Rationale: Just Culture distinguishes between human error (including at-risk
behavior influenced by system factors), reckless behavior, and intentional unsafe acts.
A nurse working a double shift who misread a label represents at-risk behavior
influenced by fatigue and system design; the response should address both
individual coaching and system improvements. Option A represents punitive blame,
contrary to Just Culture. Option B is disproportionate and bypasses internal quality
improvement. Option D ignores the opportunity to prevent future errors.
Correct Answer: C
Q5. A surgical unit is analyzing pre-operative checklist compliance using Six Sigma
methodology. The team measures that checklists are completed correctly 94% of the
time. In Six Sigma terms, this represents approximately:
A. 1 Sigma performance
B. 2 Sigma performance
C. 3 Sigma performance [CORRECT]
D. 6 Sigma performance
Rationale: Three Sigma performance corresponds to approximately 93.3% accuracy
(6,210 defects per million opportunities), which aligns with 94% compliance. One
