CPR First Aid: Wounds, Burns and Shock

Question 1

What is the primary first aid treatment for a minor laceration (cut) with active bleeding?

Accepted Answer

Apply direct pressure with a clean cloth or bandage for at least 5-10 minutes without lifting to check

Answer

Direct pressure is the most effective first-line method to control bleeding; sustained pressure allows clotting to occur.

Question 2

What is the 'Rule of Nines' used for in burn assessment?

Accepted Answer

To estimate the total body surface area (TBSA) affected by burns for fluid resuscitation calculations

Answer

The Rule of Nines divides the adult body into areas of 9% or 18% TBSA to quickly estimate total burned surface area for guiding treatment.

Question 3

How are burn injuries classified by depth, and what characterizes each degree?

Accepted Answer

First-degree (superficial, redness only), Second-degree (partial thickness, blisters), Third-degree (full thickness, white/charred, painless), Fourth-degree (charred to bone/muscle)

Answer

Burns are classified by depth: first-degree (superficial), second-degree (partial thickness with blisters), third-degree (full thickness, painless), fourth-degree (extending to muscle/bone).

Question 4

What is the correct first aid treatment for a chemical burn to the skin?

Accepted Answer

Immediately flush with large amounts of cool running water for at least 20 minutes, while removing contaminated clothing and jewelry

Answer

Continuous water irrigation for at least 20 minutes is the most effective treatment for chemical burns—neutralizers can generate heat and worsen injury.

Question 5

What are the three stages of burn shock, and when does it typically begin?

Accepted Answer

Fluid shift/hypovolemic phase (0-48 hours), diuretic phase (48-72 hours), recovery—shock begins within minutes to hours of significant burn

Answer

Major burns cause massive fluid shift into the wound and surrounding tissue (capillary leak), leading to hypovolemic shock within hours.
