In the case of uncontrolled bleeding from a stab wound, what should be done?

In cases of uncontrolled bleeding from a stab wound, applying a tourniquet proximal to the injury is the correct course of action. A tourniquet is used to occlude blood flow to the affected limb, which is crucial in situations where significant blood loss is occurring. By placing the tourniquet above the wound, you effectively restrict arterial blood flow, minimizing blood loss until further medical intervention can be provided.

This method is especially important in severe trauma situations where time is critical, and the risk of exsanguination (extreme blood loss) is high. Depending on the location of the wound, evaluating the anatomy of the limb helps determine the appropriate placement of the tourniquet to ensure it is effective in controlling the hemorrhage.

Other options such as applying a tourniquet directly over the wound do not effectively control the bleeding, as it may not adequately restrict the blood vessels involved. Elevating the extremity above the heart can help reduce swelling and may slow down bleeding but is not sufficient alone for immediate control of heavy bleeding. Applying a pressure point may also assist in controlling blood flow but is less effective than a well-placed tourniquet for major bleeding situations, particularly in serious hemorrhage scenarios.
