Waddell’s triad of injuries is seen in:
**Core Concept**
Waddell's triad is a pattern of injury seen in pediatric trauma patients, involving a combination of injuries to the chest, abdomen, and legs. This triad is a result of the mechanism of injury, typically involving a high-speed motor vehicle collision. The **pathophysiology** of these injuries is related to the force exerted on the body during the crash.
**Why the Correct Answer is Right**
The correct answer is related to the mechanism of injury that leads to Waddell's triad. The triad consists of a **chest** injury, often a pulmonary contusion, an **abdominal** injury, which may involve solid organs, and a **lower extremity** injury, typically a femur fracture. This pattern of injury is seen in children who are struck by a vehicle or involved in a high-speed collision.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Waddell's triad is not typically associated with this type of injury pattern.
**Option B:** This option is also incorrect as it does not accurately describe the injuries seen in Waddell's triad.
**Option C:** This option is incorrect because it is not related to the mechanism of injury that leads to Waddell's triad.
**Clinical Pearl / High-Yield Fact**
Waddell's triad is an important concept in pediatric trauma, as it requires a high index of suspicion for associated injuries. The **key** to recognizing Waddell's triad is to consider the mechanism of injury and to evaluate the patient carefully for all components of the triad.
**Correct Answer:** D. Pediatric trauma, specifically a child hit by a car, with injuries to the chest, abdomen, and legs.
