Which option best defines the description of third-degree burns?

• A. Burns that destroy the entire thickness of the skin
• B. Partial thickness burns
• C. Superficial burns
• D. Subcutaneous tissue only

Answer: (A)

Third-degree burns are full-thickness injuries. They destroy the entire thickness of the skin, meaning the epidermis and all layers of the dermis, often extending into subcutaneous tissue and sometimes underlying structures. Because the nerves in the skin are destroyed, the burned area can be insensitive to pain, though surrounding tissue may be very painful. The skin feels leathery or firm (eschar) and may appear white, brown, tan, or black. This loss of the protective barrier and blood vessels leads to high infection risk and fluid loss, so these wounds typically require surgical management such as debridement and grafting rather than natural healing. In contrast, partial-thickness burns involve the epidermis and part of the dermis, and superficial burns involve only the epidermis.
