How do you correctly apply a tourniquet for severe limb bleeding?

• A. Place it 2-3 inches above the wound (not over a joint), tighten until bleeding stops, secure, and record the time applied.
• B. Place it 6 inches above the wound.
• C. Apply a tourniquet only after applying a pressure dressing.
• D. Place it directly over the wound.

Answer: (A)

Controlling severe limb bleeding with a tourniquet relies on stopping arterial blood flow to the injured area while keeping the device in a place that can reliably compress the vessels. The correct method places the tourniquet about 2-3 inches above the wound, toward the torso, and never over a joint. This position lets the tourniquet bite into solid tissue and effectively press on the arteries supplying the limb, without the risk of the device slipping over a bendy joint or directly over the wound. Tightening it until the bleeding stops is essential because you’re aiming to completely halt arterial inflow, not just reduce it. Once the bleeding is controlled, secure the tourniquet so it won’t loosen, and record the time it was applied. The time note is critical for medical responders, since prolonged tourniquet use increases the risk of tissue damage and helps guide care as the patient is transported. Why the other ideas don’t fit: placing the tourniquet too far above the wound (for example, six inches) can make it harder to compress the correct vessels and may reduce effectiveness, while placing it directly over the wound or over a joint risks tissue injury and may not provide reliable arterial compression.
