when placing a tourniquet on an arm or a leg, which of the following is the correct placement?

When placing a tourniquet on an arm or leg, the correct placement is to position the tourniquet 2 to 3 inches above the wound, between the wound and the heart (proximal to the wound). The tourniquet should not be placed directly over the wound or over a joint (such as an elbow or knee) to avoid ineffective compression or injury. Ideally, it should be placed high and tight, as close to the torso as possible on the injured limb, especially in emergency or active threat situations, but if the wound's location is known and there is time, placing it 2-3 inches above the wound is preferred to maximize effectiveness and minimize complications.
