OFA Wound Care & Bleeding Control 3

Question 1

What is the primary purpose of wound irrigation in first aid?

Accepted Answer

To remove debris and reduce the risk of infection

Answer

Irrigation with clean water or saline flushes out contaminants and bacteria, significantly reducing the risk of wound infection.

Question 2

When is it appropriate to use a hemostatic dressing (e.g., Combat Gauze) in an occupational first-aid setting?

Accepted Answer

For life-threatening hemorrhage where direct pressure alone is insufficient

Answer

Hemostatic dressings are reserved for severe, life-threatening bleeding that cannot be controlled by direct pressure alone.

Question 3

A co-worker's wound has bright red blood spurting in rhythm with the heartbeat. Which vessel is most likely injured?

Accepted Answer

An artery

Answer

Arterial blood is oxygenated and under high pressure, causing it to spurt in pulses synchronized with the heartbeat.

Question 4

What is 'wound evisceration' and what is the correct first-aid response?

Accepted Answer

Organs protruding from an abdominal wound; cover with a moist sterile dressing and do not push organs back in

Answer

Evisceration involves abdominal organs protruding through a wound; they must be covered with moist sterile material and never forced back in.

Question 5

Which sign indicates that a dressing over a wound is no longer effective and needs to be changed?

Accepted Answer

Blood has soaked through the outer layer of the dressing

Answer

Strike-through (blood soaking through to the outer layer) indicates the dressing is saturated; add additional dressings on top and continue pressure.
