Question

a victim who has an injured femur is likely to exhibit signals of shock because—
○ a fractured femur can result in serious bleeding.
○ the femur is the biggest bone in the body.
○ the injured leg often turns outward from the body.
○ all of the above

Explanation:

A fractured femur can lead to significant internal bleeding as there are major blood vessels around the femur. Shock can occur due to blood loss. While the femur is the largest bone (which can contribute to more potential for damage and bleeding) and a fractured femur may cause the leg to turn outward (a sign of the injury but not a direct cause of shock), the primary reason for shock signals is the potential for serious bleeding from a fractured femur.

Answer:

A. A fractured femur can result in serious bleeding.
