A patient is brought into the emergency department with fractured left femur, tibia, and fibula with a mild contralateral head injury. The nurse would correctly suspect that this patient's mechanism of injury would be
1. child pedestrian hit by an automobile.
2. adult pedestrian hit by an automobile.
3. unrestrained driver of a motor vehicle.
4. unrestrained front seat passenger of a motor vehicle.

Rationale: The injuries of a fractured femur, tibia, and fibula on the same side with a contralateral head injury would indicate the patient was a pedestrian and hit by a motor vehicle. A child pedestrian would have a chest injury in addition to the limb and head injury. An unrestrained driver of a motor vehicle would have extensive injuries to the head, neck, thorax, abdomen, and lower extremities. An unrestrained front seat passenger of a motor vehicle would have facial and lower extremity injuries.
