Which event is listed as an example when describing mechanism of injury?

• A. Stroke
• B. Fall injury
• C. Asthma attack
• D. Dehydration

Answer: (B)

Mechanism of injury refers to how energy is transferred to the body during an incident to cause injury. A fall injury is an example because it involves an external force delivering impact to the body, which can produce tissue damage such as fractures or head injury depending on height and surface. The other options describe medical conditions rather than the event that caused traumatic injury: a stroke is a brain event from disrupted blood flow, an asthma attack is airway constriction, and dehydration is a fluid/imbalanced condition. So the fall injury best illustrates the idea of an injury caused by an external energy transfer.
