Third-degree burns are defined as burns that:

• A. Heal without significant intervention.
• B. Involve only the epidermis.
• C. Destroy the entire thickness of the skin.
• D. Cause blisters.

Answer: (C)

Full-thickness destruction of the skin defines a third-degree burn. This means the injury goes through both the epidermis and the entire dermis, and often extends into underlying tissues. Because all skin layers are damaged, the burned area may look white, brown, red, or charred and can be numb at the center due to nerve ending destruction, with surrounding tissue that is very painful from partial-thickness burns. Deep burns like this require medical treatment such as debridement and often skin grafting, and healing is typically prolonged with a high risk of scarring. This depth differentiates third-degree burns from first-degree burns, which affect only the outer epidermis and heal without scars, and second-degree burns, which involve the epidermis and part of the dermis and usually produce blisters and significant pain.
