A 44-year-old male with burns to the anterior trunk and both arms has partial‑thickness burns that cover what percentage of total body surface area?

Explanation:
Think about TBSA estimation with the Rule of Nines. Anterior trunk accounts for 18% of TBSA, and each arm accounts for 9%, so both arms add 18%. Together with the anterior trunk, that’s 18% + 18% = 36%. Depth-wise, partial-thickness means second-degree burns, involving the epidermis and part of the dermis. That fits the description of partial-thickness burns over those areas. So the burns described are partial-thickness, totaling 36% of the body surface area.
