1In James Reason's Swiss cheese model of accident causation, what do the 'holes' in each slice of cheese represent?

A.Active and latent weaknesses in successive layers of defense

B.Individual clinicians who lack competence

C.Mandatory reporting requirements

D.Steps in a clinical care pathway

Explanation: In the Swiss cheese model, each slice is a layer of defense, and the holes represent active failures and latent conditions. An adverse event occurs when holes in successive layers momentarily align, allowing a hazard to pass through all defenses and reach the patient.

2A nurse programs an infusion pump incorrectly at the bedside, immediately causing an overdose. According to James Reason, this is best classified as which type of failure?

A.A latent failure

B.A never event by definition

C.A normal accident

D.An active failure

Explanation: Active failures are errors of commission or omission committed at the human-system interface (the 'sharp end') whose effects are felt almost immediately. A misprogrammed pump at the bedside is a classic active failure, in contrast to latent failures that lie dormant in system design.

3Which of the following is an example of a latent condition rather than an active failure?

A.A surgeon nicking an artery during dissection

B.A pharmacist mistyping a dose into the order

C.Understaffing and poor pump-interface design set by management years earlier

D.A technician mislabeling a specimen tube

Explanation: Latent conditions are decisions and design choices (staffing models, equipment selection, policies) made far from the bedside that lie dormant until they combine with active failures to produce harm. Chronic understaffing and a confusing pump interface are latent conditions.

4Which HRO principle is demonstrated when a hospital treats every near miss as a signal of possible system weakness rather than as proof that 'no harm, no foul'?

A.Reluctance to simplify

B.Preoccupation with failure

C.Deference to expertise

D.Commitment to resilience

Explanation: Preoccupation with failure means high-reliability organizations attend to weak signals such as near misses and close calls, treating them as opportunities to learn before serious harm occurs, rather than celebrating that no one was hurt.

5During a deteriorating-patient emergency, the most experienced respiratory therapist overrides the junior physician's plan and the team follows the therapist's judgment. Which HRO principle does this illustrate?

A.Sensitivity to operations

B.Preoccupation with failure

C.Reluctance to simplify

D.Deference to expertise

Explanation: Deference to expertise means that during a crisis, decision-making authority migrates to the person with the most relevant knowledge regardless of rank, reducing the authority gradient that can block safe communication.

6Weick and Sutcliffe identified five principles of high-reliability organizations. Which set correctly lists them?

A.Standardization, automation, redundancy, audit, discipline

B.Preoccupation with failure, reluctance to simplify, sensitivity to operations, commitment to resilience, deference to expertise

C.Plan, do, study, act, sustain

D.Severity, occurrence, detection, mitigation, control

Explanation: Weick and Sutcliffe's five HRO principles are preoccupation with failure, reluctance to simplify interpretations, sensitivity to operations, commitment to resilience, and deference to expertise. Together they describe how organizations detect weak signals and respond mindfully.

7Which intervention is generally the MOST reliable way to prevent a recurring error, because it does not depend on human memory or vigilance?

A.Adding a warning sign to the device

B.Re-educating staff on the correct procedure

C.A forcing function that makes the wrong action physically impossible

D.Writing a new policy reminding staff to be careful

Explanation: Forcing functions (constraints that physically prevent the unsafe action, such as incompatible connectors) are among the strongest, highest-reliability interventions because they do not rely on people remembering or paying attention. Education, signage, and policies are weaker because they depend on human performance.

8A patient safety officer is asked to explain the difference between a system-focused and a person-focused approach to error. Which statement best describes the system approach?

A.It concentrates on identifying and disciplining the individual who erred

B.It assumes errors are moral failures requiring retraining

C.It accepts that humans are fallible and redesigns conditions to reduce error and catch it before harm

D.It relies primarily on increasing individual effort and vigilance

Explanation: The system approach, articulated by James Reason, accepts that human fallibility is inevitable and focuses on building defenses and redesigning conditions of work so that errors are less likely and are intercepted before reaching the patient. The person approach blames individuals.

9The landmark 1999 Institute of Medicine report that brought national attention to medical error and estimated up to 98,000 preventable deaths per year in U.S. hospitals was titled:

A.Crossing the Quality Chasm

B.To Err Is Human: Building a Safer Health System

C.Free from Harm

D.Preventing Medication Errors

Explanation: 'To Err Is Human: Building a Safer Health System' (IOM, 1999) estimated that 44,000 to 98,000 Americans died each year from preventable medical errors and is widely credited with launching the modern patient safety movement and its systems orientation.

10A patient safety culture survey shows staff strongly agree that 'leadership only hears about safety problems after something goes wrong.' Which HRO principle is most directly weak in this unit?

A.Sensitivity to operations

B.Deference to expertise

C.Commitment to resilience

D.Reluctance to simplify

Explanation: Sensitivity to operations means leaders and teams maintain an accurate, real-time picture of front-line work and emerging risks. When problems only surface after harm, the organization lacks the ongoing situational awareness that this principle requires.
