First Aid Bleeding, Wounds, and Shock 4

Question 1

A child falls and has a scalp laceration bleeding heavily. You know scalp wounds bleed profusely. What is your first action?

Accepted Answer

Apply firm direct pressure with a clean cloth

Answer

Apply firm direct pressure with a clean cloth to control scalp bleeding; scalp wounds bleed heavily due to rich vascularization but respond well to pressure.

Question 2

A victim with a suspected spinal injury is in shock. How should you position them?

Accepted Answer

Keep them flat and still; move only if in immediate danger

Answer

When spinal injury is suspected, keep the victim flat and minimize movement to avoid spinal cord damage, even if shock positioning is otherwise indicated.

Question 3

Anaphylactic shock differs from hypovolemic shock in that anaphylactic shock is caused by:

Accepted Answer

A severe allergic reaction causing vasodilation and fluid leakage

Answer

Anaphylactic shock is triggered by a severe allergic reaction that causes widespread vasodilation and increased capillary permeability, causing a drop in blood pressure.

Question 4

Which wound type has the highest risk of becoming infected due to bacterial contamination from a human or animal source?

Accepted Answer

Bite wound

Answer

Bite wounds carry a very high infection risk because human and animal mouths harbor numerous bacteria, including pathogens like Pasteurella and MRSA.

Question 5

You are treating an open chest wound (sucking chest wound). What specialized first aid dressing is recommended?

Accepted Answer

A vented chest seal or three-sided occlusive dressing

Answer

A vented (three-sided) chest seal or commercial chest seal allows air to escape on exhalation while preventing air from entering, reducing the risk of tension pneumothorax.
