What does Waddell's triad describe?

1. A pattern of injury observed when an adult is hit by a vehicle

2. An injury pattern observed when a child gets hit by a car

3. The relationship between speed and impact injuries

4. A classification system for trauma care

The correct answer is: An injury pattern observed when a child gets hit by a car

Waddell's triad specifically refers to a characteristic pattern of injuries sustained by a child who has been struck by a vehicle. The triad typically includes a combination of injuries to the lower extremities, the abdomen or thorax, and the head. This pattern is particularly relevant in pediatric medicine and trauma assessment, as it helps medical professionals recognize the typical injuries associated with child pedestrian accidents. Understanding this triad is crucial for accurate diagnosis and treatment of traumatic injuries in young patients. The other options discuss various aspects of trauma and injury mechanisms but do not accurately define Waddell's triad. For instance, the concept of injury patterns in adults hit by vehicles and trauma classification systems pertains to different areas of study in trauma care and do not specifically relate to the unique injury patterns seen in pediatric cases. Thus, recognizing Waddell’s triad as an injury profile for children is essential for effective trauma assessment and intervention.
