How are burns categorized?

• A. Size: by percent burned; Depth: superficial partial thickness, deep partial thickness, full thickness
• B. Size: by percent burned; Depth: epidermal, dermal, subcutaneous
• C. Size: by area; Depth: epidermal, dermal, subcutaneous
• D. Size: according to rule of 9's; Depth: superficial partial thickness, deep partial thickness, full thickness

Answer: (D)

Burns are understood by two main factors: how much of the body is burned and how deeply the skin is damaged. The extent, or size, is estimated as a percentage of total body surface area (TBSA). For a quick and widely used method in adults, clinicians apply the Rule of Nines to approximate TBSA burned. The depth describes how far the injury goes into skin layers: superficial partial-thickness involves the outer layer and part of the dermis, deep partial-thickness goes deeper into the dermis, and full-thickness destroys the entire skin thickness and can affect underlying tissues. This option is best because it pairs the standard size estimation method (Rule of Nines) with the clinically relevant depth categories (superficial partial thickness, deep partial thickness, full thickness). The other descriptions are less precise for depth in common clinical use, or refer to anatomical layers without framing them in the clinical depth categories used for burn assessment.
