Which depth categories are used to describe burns?

• A. Partial thickness, full thickness
• B. First degree, second degree, third degree
• C. Superficial partial thickness, deep partial thickness, full thickness
• D. Epidermal, dermal, subcutaneous

Answer: (C)

Burn depth is best described by three levels that reflect how much of the skin’s structure is damaged and how this affects healing and treatment: superficial partial thickness, deep partial thickness, and full thickness. Superficial partial thickness involves the epidermis and the upper part of the dermis. The skin is usually very painful, red, blistered, and moist; these burns tend to heal relatively quickly, often without grafting, with minimal scarring. Deep partial thickness reaches deeper into the dermis, sometimes burning into the deeper dermal layers. Pain may be present but diminished because nerve fibers are damaged; the wound often appears mottled red or white with blisters and heals more slowly, with a higher chance of scarring and a possible need for grafting. Full thickness destroys the entire epidermis and dermis and may extend into subcutaneous tissue or beyond. The skin feels leathery or waxy and is typically insensate due to nerve destruction; such burns require surgical debridement and grafting, and scarring is common. Options describing only partial thickness without distinguishing superficial from deep, or using first/second/third degree, or listing only epidermal/dermal/subcutaneous layers, are less precise for guiding prognosis and management. The three-part classification with superficial partial thickness, deep partial thickness, and full thickness best captures the clinically relevant depth and healing implications.
