What are three methods of controlling external bleeding?

The correct answer is based on the most effective and widely accepted methods for controlling external bleeding. Direct pressure is the primary method used to manage bleeding and involves applying firm pressure directly to the wound. This helps to compress the blood vessels and reduces blood loss. Pressure dressing involves applying a bandage with enough pressure to control bleeding while allowing for movement. This is vital for wounds that continue to bleed even after direct pressure is applied. If these methods are not sufficient, a tourniquet can be employed as a last resort for severe bleeding, particularly in limbs. It restricts blood flow and is a critical tool in emergency medical situations where life-threatening bleeding occurs.

Other options include methods or terms that may not be the best practice for managing bleeding. For example, suturing is typically a technique used to close a wound rather than a method for initially controlling bleeding. Elevation alone may not effectively address severe bleeding, and while ice application can reduce swelling and slow bleeding in some cases, it is not a primary method for controlling bleeding. Thus, the choice that includes direct pressure, pressure dressing, and tourniquet encompasses the most effective strategies for immediate response to external bleeding.
