Identify which burns count toward total body surface area (TBSA) calculation. Select all that apply.

A. Deep partial-thickness: These burns extend into the deeper dermis, damaging nerve endings and blood vessels. Because they affect significant tissue layers and fluid balance, they are included in TBSA calculations. B. Full-thickness: Full-thickness burns destroy the entire dermis and epidermis, often requiring grafting for healing. They significantly affect fluid shifts and metabolic needs, so they are always counted in TBSA. C. Superficial partial-thickness: These burns extend into the upper dermis and cause blistering and pain. Since they involve more than just the epidermis, they are included in TBSA calculations to guide fluid resuscitation. D. Superficial/epidermal: These burns only affect the epidermis, similar to mild sunburn. They do not cause major fluid or electrolyte imbalance and are not included in TBSA calculations.
