Question 1
A hospital wants to identify the underlying causes of a serious
medication error that reached a patient. Which method is most
appropriate?
A. Benchmarking
B. Root cause analysis
C. Staff satisfaction survey
D. Financial variance analysis
Answer: B. Root cause analysis
Rationale: Root cause analysis (RCA) is a structured,
retrospective approach used to identify system and process
factors that contributed to an adverse event and to develop
strategies to reduce recurrence.
Question 2
,Which statement best describes a just culture?
A. Employees are never held accountable for errors
B. All errors should result in disciplinary action
C. The organization distinguishes human error, at-risk behavior,
and reckless behavior
D. Only physicians are accountable for patient-safety events
_Answer: C. The organization distinguishes human error,
at-risk behavior, and reckless behavior
Rationale: Just culture promotes learning from errors while
maintaining appropriate accountability. It recognizes that
human error differs from behaviors involving conscious risk-
taking or disregard for substantial safety risks.
Question 3
A nurse accidentally selects the wrong medication because two
products have nearly identical packaging. Which intervention is
most consistent with the hierarchy of controls?
A. Tell nurses to be more careful
B. Send an educational email
C. Separate the medications physically and use distinct labeling
D. Ask nurses to sign an acknowledgment form
_Answer: C. Separate the medications physically and use
distinct labeling
Rationale: Engineering or design changes are generally
stronger controls than relying solely on education, reminders, or
individual vigilance.
,Question 4
Which measure is an example of a process measure?
A. Mortality rate
B. Patient injury rate
C. Percentage of patients receiving medication reconciliation at
admission
D. Number of malpractice claims
_Answer: C. Percentage of patients receiving medication
reconciliation at admission
Rationale: A process measure evaluates whether a desired
action or step in care is being performed. Medication
reconciliation completion is a process measure.
Question 5
A patient-safety team notices that a problem occurs more
frequently during certain shifts. Which tool would be most
useful for displaying event frequency by time period?
A. Run chart
B. Fishbone diagram
C. Scatter diagram
D. Process map
_Answer: A. Run chart
Rationale: A run chart displays data over time and can help
teams recognize patterns, shifts, or trends in performance.
Question 6
, Which action best supports high-reliability organization
principles?
A. Accepting recurring errors as unavoidable
B. Focusing primarily on individual blame
C. Remaining attentive to weak signals and system
vulnerabilities
D. Avoiding reporting of near misses
_Answer: C. Remaining attentive to weak signals and system
vulnerabilities
Rationale: High-reliability organizations emphasize sensitivity
to operations, preoccupation with failure, resilience, and
continuous attention to potential hazards.
Question 7
What is the primary purpose of reporting a near miss?
A. To punish the employee involved
B. To identify opportunities for preventing future harm
C. To calculate employee productivity
D. To eliminate the need for incident investigation
_Answer: B. To identify opportunities for preventing future
harm
Rationale: Near misses provide valuable information about
system vulnerabilities before patient harm occurs and can guide
preventive improvements.
