What is the recommended sequence for life-threatening hemorrhage control in the field?

• A. Direct pressure, elevation, and if bleeding remains uncontrolled, apply a tourniquet and seek emergency care.
• B. Apply a tourniquet immediately without any direct pressure.
• C. Ignore bleeding and continue activity.
• D. Only use a tourniquet if there is a visible artery.

Answer: (A)

The sequence tested is about stopping life-threatening bleeding in the field using a logical, escalating approach. Start with direct pressure on the wound because pressing hard over the bleeding source is the most reliable way to form a clot and slow or stop bleeding quickly. If bleeding continues, raise the injured limb when feasible to reduce blood flow to the area, helping direct pressure work more effectively. If the bleeding remains uncontrolled after these steps, apply a tourniquet tightly around the limb, proximal to the wound, to halt arterial flow and save the person’s life. Then get emergency care as soon as possible.

This order matters because it prioritizes the simplest, most effective method first (direct pressure), adds a supportive step (elevation) to aid control, and reserves the tourniquet as a necessary move when bleeding cannot be controlled by initial measures. Rationale against the other ideas: using a tourniquet right away without attempting direct pressure may miss a quick, noninvasive way to stop the bleed; ignoring the bleed or continuing activity is dangerous; a tourniquet is not limited to cases with visible artery signs and should not be the sole strategy without trying pressure first.
