In a trauma patient with a suspected femur fracture, which complication should paramedics treat?

• A. Shock
• B. DVT
• C. Infection
• D. Circulatory compromise

Answer: (A)

The most important idea here is that a femur fracture in a trauma patient carries a high risk of rapid blood loss, which can lead to hypovolemic shock. The femur has a large medullary cavity and extensive surrounding vascular tissue, so a fracture can bleed internally enough to compromise circulation quickly. In the field, the priority is to prevent or treat that shock: provide high-flow oxygen to optimize oxygen delivery, control any bleeding with direct pressure if present, immobilize the leg to minimize further injury and pain (often with a traction splint when appropriate and per protocol), and arrange rapid transport to a definitive care facility. Keeping the patient warm and monitoring vitals helps detect deterioration early. DVT or infection may develop later, but they aren’t the immediate threat to address in this scenario, whereas shock reflects the urgent need to maintain tissue perfusion.
