A 25-year-old burn patient has burns over the entire anterior trunk, the entire right upper limb, and the entire right lower limb. Using the Rule of Nines, what is the total body surface area (TBSA) burned?

• A 36%
• B 40.5%
• C 49.5%
• D 45% ✓

Explanation

By the adult Rule of Nines: entire anterior trunk (chest + abdomen) = 18%; entire right upper limb = 9%; entire right lower limb = 18%. Total = 18 + 9 + 18 = 45%. For reference, the other regions are head and neck = 9%, each entire upper limb = 9%, each entire lower limb = 18%, and the perineum = 1%.
