OFA Wound Care & Bleeding Control

Question 1

What is the first step in controlling external bleeding?

Accepted Answer

Apply direct pressure to the wound

Answer

The most immediate and effective first step in controlling external bleeding is to apply firm, direct pressure directly onto the wound with a clean dressing or cloth. This pressure helps to compress the blood vessels and promote clotting, thereby reducing blood loss.

Question 2

When should you use a tourniquet?

Accepted Answer

Only if bleeding continues after applying direct pressure

Answer

A tourniquet is a last resort for severe, life-threatening bleeding that cannot be controlled by direct pressure or pressure bandages. It works by completely stopping blood flow to the limb, which can cause tissue damage, so it should only be used when other methods have failed and the bleeding poses an immediate threat to life.

Question 3

What is a sign of internal bleeding?

Accepted Answer

Bruising, rapid pulse, and pale skin

Answer

Internal bleeding occurs when blood vessels inside the body are damaged, leading to blood loss within body cavities or tissues. Signs like bruising, a rapid and weak pulse (indicating the body's attempt to compensate for blood loss), and pale, cool, clammy skin (due to reduced blood volume and shock) are key indicators of internal hemorrhage.

Question 4

How should you treat a nosebleed?

Accepted Answer

Lean forward and pinch the nostrils together

Answer

To treat a nosebleed, the person should lean slightly forward to prevent blood from flowing down the throat, which can cause nausea or choking. Pinching the soft part of the nostrils together for 10-15 minutes applies direct pressure to the bleeding vessels, helping the blood to clot and stop the flow.

Question 5

Which of the following is NOT a recommended action for treating a minor wound?

Accepted Answer

Remove deeply embedded objects

Answer

For minor wounds, cleaning, dressing, and applying antibiotic ointment are appropriate steps. However, deeply embedded objects should never be removed by a first aid responder, as this can cause further damage, increased bleeding, or introduce infection. Such objects should be stabilized and left for medical professionals to remove.
