When applying a tourniquet, where should it be positioned?

• A. Directly over the injury
• B. 2-3 inches proximal to the wound
• C. At the distal end of the limb
• D. At the nearest joint to the wound

Answer: (B)

The optimal positioning of a tourniquet is crucial for effectively controlling severe bleeding. When a tourniquet is placed 2-3 inches proximal to the wound, it provides the best opportunity to occlude the arterial supply to the bleeding site while minimizing potential damage to tissues and nerves. This positioning allows the tourniquet to compress the blood vessels effectively, significantly improving the chances of managing hemorrhagic shock and preserving life. Placing the tourniquet directly over the injury might not provide adequate compression to the underlying arteries, especially if the wound involves more significant blood vessel damage or is located deeper in the tissue. Additionally, positioning it at the distal end of the limb or at the nearest joint could fail to stop the blood flow entirely and wouldn’t ensure effective stabilization of the injury, leading to complications. Therefore, applying the tourniquet 2-3 inches proximal to the wound is the best practice for maintaining control over a significant bleeding event.
