First Aid Bleeding and Wound Care 5

Question 1

In a mass casualty situation with limited supplies, which bleeding wound takes the highest priority for tourniquet use?

Accepted Answer

Arterial bleeding from an amputated leg that cannot be controlled by pressure

Answer

Arterial hemorrhage from traumatic amputation is immediately life-threatening and requires tourniquet application when direct pressure fails.

Question 2

Which of the following is a late sign of significant blood loss indicating severe hemorrhagic shock?

Accepted Answer

Unresponsiveness and absent radial pulse

Answer

Loss of consciousness and absent peripheral pulses indicate decompensated shock — a critical emergency requiring immediate EMS intervention.

Question 3

A hiker has a wound that occurred 2 days ago and now shows redness spreading from the edges, warmth, and pus. These are signs of:

Accepted Answer

Wound infection requiring medical evaluation

Answer

Spreading erythema, warmth, and purulent discharge after 48 hours indicate wound infection requiring medical treatment, possibly antibiotics.

Question 4

Why should you avoid applying a tourniquet directly over a joint such as the knee or elbow?

Accepted Answer

The joint's anatomy prevents adequate compression of the artery

Answer

Joints lack the flat bone surface needed to compress vessels effectively, making tourniquets ineffective over them.

Question 5

A person has a wound on their palm that is bleeding steadily. What is the best way to apply pressure while keeping your hands free?

Accepted Answer

Have them make a fist around the dressing to self-compress the wound

Answer

Having the patient make a fist over a dressing applies effective palm pressure and frees the rescuer to manage other tasks.
