Question

1. select all that apply.

choose two facts about tourniquets.

• only use a tourniquet for severe bleeding from arms or legs.
• keep the tourniquet in place for at least three hours to prevent additional bleeding.
• place the tourniquet 2-3 inches below the wound, between the wound and the hand or foot.
• only use a tourniquet as a last resort as it can cause permanent damage.

Explanation:

1. For the first option: Tourniquets are used for severe bleeding in extremities (arms/legs) as other methods may not work, so this is correct.
2. For the second option: Tourniquets shouldn't be left for 3 hours; they should be removed or adjusted after professional help or when bleeding is controlled, so this is incorrect.
3. For the third option: Tourniquets are placed above the wound (between wound and heart), not below, so this is incorrect.
4. For the fourth option: Tourniquets can cause tissue damage, nerve injury, etc., so they're a last resort, making this correct.

Answer:

A. Only use a tourniquet for severe bleeding from arms or legs.
D. Only use a tourniquet as a last resort as it can cause permanent damage.
