Which of the following procedures is essential for managing severe bleeding?

Using a tourniquet is a critical life-saving measure for managing severe bleeding, particularly in cases of traumatic injury where direct pressure is insufficient to control the hemorrhage. When blood loss is significant and life-threatening, a tourniquet can effectively occlude blood flow to the affected limb, minimizing blood loss and providing time for definitive medical intervention.

This procedure is especially vital in scenarios where injuries involve major arteries, as rapid and effective management can prevent shock and increase the chances of survival. The application of a tourniquet should be done judiciously and in accordance with established protocols, ensuring that it is placed proximal to the wound and tightened adequately to stop bleeding.

While applying a sterile dressing, giving oral fluids, and checking pulse are important components of overall patient care, they do not directly control severe bleeding as effectively as a tourniquet does in critical situations.
