Approximately how much blood loss can occur from a femur injury?

100 mL
500 mL
1000 mL
1500 mL

The correct answer is: 1500 mL

A femur injury can lead to significant blood loss due to the artery-rich anatomy of the thigh. The correct choice reflects the potential for extensive bleeding associated with fractures in this area. When a femoral shaft fracture occurs, it can sever the femoral artery or lead to hemorrhage from surrounding soft tissues, which can result in a loss of approximately 1,500 mL of blood. This amount of blood loss is critical and can quickly lead to shock if not addressed promptly. EMTs should be aware of this potential for severe hemorrhage and prioritize control measures, such as direct pressure, elevation, and possibly the use of tourniquets, in their assessment and management of patients with suspected femur fractures. Recognizing this can significantly alter the urgency and approach to treatment in trauma scenarios.
