What should be done if direct pressure fails to control bleeding from a limb?

• A. Elevate the limb
• B. Apply a tourniquet above the injury
• C. Use ice on the wound
• D. Apply a sterile dressing only

Answer: (B)

In situations where direct pressure fails to control bleeding from a limb, applying a tourniquet above the injury is a critical step. When direct pressure is not effective, it indicates that there is significant arterial bleeding that cannot be managed through conventional methods. A tourniquet works by compressing the blood vessels in the limb more effectively than manual pressure can achieve. Its purpose is to stop the flow of blood and prevent further blood loss, thereby reducing the risk of hypovolemic shock or death. Proper application of a tourniquet can be life-saving, especially in acute, traumatic situations where bleeding is severe. While elevating the limb, using ice, or applying a sterile dressing may be helpful initial measures in some contexts, none of these actions are as effective as a tourniquet in controlling severe, life-threatening bleeding. Elevation may not suffice to stop arterial bleeding, ice is unlikely to provide immediate control, and a sterile dressing alone does not apply sufficient pressure to manage a major hemorrhage. Thus, utilizing a tourniquet is the best practice in such circumstances.
