Which of the following best represents the Just Culture of Safety model?
Bird's safety triangle
Reason's Swiss Cheese model
Heinrich's domino model of accident causation
Rasmussen's drift into failure model
The Correct Answer is B
Choice A reason: Bird’s safety triangle focuses on accident statistics and incident ratios, not systemic safety culture.
Choice B reason: Reason’s Swiss Cheese model illustrates that errors occur when multiple system defenses fail, emphasizing a culture of safety that examines latent failures and prevents blame, which aligns with the Just Culture approach.
Choice C reason: Heinrich’s domino model attributes accidents primarily to individual error, not systemic factors, and is less aligned with Just Culture principles.
Choice D reason: Rasmussen’s drift into failure model emphasizes gradual erosion of safety through organizational drift, which is related to but does not define the Just Culture model.

Correct Answer is B
Explanation
Choice A reason: While parental assistance may influence outcomes, framing it as “cheating” is inappropriate and may create unnecessary anxiety.
Choice B reason: ADOS evaluates a child’s social and communication abilities independently. Parents must leave so the examiner can observe the child’s behaviors without external influence, ensuring accurate assessment.
Choice C reason: Difficulty in observing the child is not the primary rationale; the goal is to evaluate independent behavior.
Choice D reason: Parental presence may affect behavior, but the main purpose is not to prevent upset, but to accurately assess skills independently.
Correct Answer is B
Explanation
Choice A reason: Attention deficit hyperactivity disorder (ADHD) is characterized by persistent patterns of inattention, hyperactivity, and impulsivity that are present across multiple settings and have existed since childhood. This patient’s symptoms are acute and situational, triggered by a recent stressor (grandfather’s illness), which makes ADHD less likely as the primary diagnosis.
Choice B reason: Adjustment disorder with mixed anxiety and mood is a stress-response syndrome that arises within three months of an identifiable stressor. The patient’s concentration problems, sadness, decreased energy, restlessness, and sleep difficulties are all temporally linked to the stressor of caring for a sick grandparent. This diagnosis fits the acute onset of emotional and behavioral changes in response to a significant life event.
Choice C reason: Separation anxiety disorder involves excessive fear or anxiety concerning separation from attachment figures. While the patient has concern for his grandfather, his anxiety is not rooted in separation from a primary attachment figure but rather in worry about the grandfather’s illness and responsibilities at home.
Choice D reason: Generalized anxiety disorder is characterized by excessive, uncontrollable worry about multiple areas of life for at least six months. The patient’s anxiety is specific to a recent stressor rather than pervasive across multiple domains, making GAD less likely.
