,Patient Safety Science & Principles (54 questions)
1. The Institute of Medicine (IOM) report "To Err is Human" estimated that how many
Americans die each year from preventable medical errors?
A. 44,000 to 98,000
B. 10,000 to 20,000
C. 100,000 to 200,000
D. 250,000 to 400,000
✓ Correct answer: A. 44,000 to 98,000
Rationale: The 1999 IOM report "To Err is Human" estimated that between 44,000 and 98,000
Americans die each year from preventable medical errors. This landmark report brought national
attention to patient safety and served as a catalyst for healthcare quality improvement initiatives
across the United States.
Why the others are wrong:
B: 10,000-20,000 is below the IOM estimates.
C: 100,000-200,000 is higher than the IOM estimates.
D: 250,000-400,000 is significantly higher than the IOM estimates.

2. The Swiss Cheese Model of accident causation, applied to healthcare, suggests that:
A. Errors occur when multiple system failures align to penetrate defenses
B. Errors are caused by individual negligence only
C. Quality improvement is unnecessary
D. Errors are rare and predictable
✓ Correct answer: A. Errors occur when multiple system failures align to penetrate defenses
Rationale: The Swiss Cheese Model, developed by James Reason, posits that errors occur when
multiple system failures (the holes in the cheese) align, allowing an adverse event to penetrate the
layers of defense. In healthcare, this means that errors are typically the result of system failures rather
than individual negligence, and multiple safeguards are needed to prevent harm.
Why the others are wrong:
B: The model emphasizes system failures, not just individual negligence.
C: The model supports the need for quality improvement.
D: Errors are common and the model explains how they occur.

,3. Which of the following is a key principle of High Reliability Organizations (HROs) in
healthcare?
A. Preoccupation with failure and reluctance to simplify
B. Focus on individual performance and blame
C. Centralized decision-making
D. Reactive approach to problems
✓ Correct answer: A. Preoccupation with failure and reluctance to simplify
Rationale: High Reliability Organizations are characterized by five key principles: preoccupation
with failure, reluctance to simplify, sensitivity to operations, commitment to resilience, and deference
to expertise. These principles help healthcare organizations operate safely despite inherently complex
and high-risk environments.
Why the others are wrong:
B: HROs avoid a blame culture and focus on system improvement.
C: HROs emphasize decentralized decision-making.
D: HROs are proactive, not reactive.

4. The term "second victim" in healthcare refers to:
A. Healthcare providers who are traumatized by an adverse event
B. The patient's family members affected by an error
C. The patient who suffers harm from an error
D. The hospital system that faces legal consequences
✓ Correct answer: A. Healthcare providers who are traumatized by an adverse event
Rationale: The "second victim" concept describes healthcare providers who experience emotional
and psychological trauma following a patient safety event. Research shows that second victims may
experience guilt, anxiety, depression, and burnout. Organizations have a responsibility to provide
support and resources to help second victims recover.
Why the others are wrong:
B: Family members are sometimes considered "second victims" but the term originally refers to providers.
C: The patient is considered the "first victim."
D: The hospital system is not referred to as a "second victim."

, 5. Which of the following is a core component of a Just Culture in healthcare
organizations?
A. Balancing accountability for system failures and individual actions
B. Punishing all errors to deter future mistakes
C. Focusing exclusively on system improvement
D. Eliminating individual responsibility
✓ Correct answer: A. Balancing accountability for system failures and individual actions
Rationale: Just Culture balances the need to hold individuals accountable for their actions with the
recognition that many errors are the result of system failures. It distinguishes between human error,
at-risk behavior, and reckless behavior, and applies appropriate responses to each. This approach
promotes safety while maintaining professional accountability.
Why the others are wrong:
B: Just Culture does not punish all errors; it differentiates between types of behavior.
C: System improvement is important but so is individual accountability.
D: Individual responsibility is not eliminated in a Just Culture.

6. The AHRQ Common Formats are used in healthcare to:
A. Standardize the reporting and classification of patient safety events
B. Reimburse providers for quality improvement
C. Establish national quality measures
D. Certify healthcare professionals
✓ Correct answer: A. Standardize the reporting and classification of patient safety events
Rationale: The Agency for Healthcare Research and Quality (AHRQ) developed Common Formats to
standardize the reporting and classification of patient safety events. These formats allow for consistent
data collection across healthcare settings, enabling better analysis of safety events and identification of
improvement opportunities.
Why the others are wrong:
B: Reimbursement is not the purpose of Common Formats.
C: Quality measures are established by other organizations.
D: Certification is not the purpose of Common Formats.
