Final answer:
In cases of complete amputation, apply a tourniquet proximal to the amputation site to control bleeding, ensuring it's not over a joint, and note the time of application.
Step-by-step explanation:
When dealing with cases of complete amputation, the application of a tourniquet is a critical step to control bleeding. A tourniquet should be placed proximal to the amputation site, which means closer to the trunk of the body and away from the amputation point.
For example, if a lower limb is amputated, the tourniquet should be applied to the thigh, but it should never be placed over a joint. It's important to apply the tourniquet as tightly as necessary to stop arterial bleeding, and to note the time of application, as prolonged tourniquet use can cause tissue damage.
