Emergency Medical Technician (EMT) Practice Test

What is the purpose of using a tourniquet in managing external bleeding?

1. prevent infection

2. minimize scarring

3. control hemorrhage

4. improve wound healing

The correct answer is: control hemorrhage

The correct answer is C. Using a tourniquet is a method to control hemorrhage, or severe bleeding, by applying pressure to the affected limb and stopping the flow of blood. Tourniquets are typically used when direct pressure or other methods are not successful in controlling bleeding. Tourniquets should only be applied in specific situations and by trained individuals as they can cause complications if not used correctly. Choices A, B, and D are incorrect because a tourniquet is not used for preventing infection, minimizing scarring, or improving wound healing. Its primary purpose is to control severe bleeding to prevent further blood loss and stabilize the patient's condition.
