In a scenario where a patient has burns to the arms and anterior trunk, what percentage of BSA is involved according to the Rule of Nines?

Explanation:
Rule of Nines estimates burn size by assigning fixed percentages to body regions. Each arm accounts for 9% (front and back together), while the anterior trunk (chest and abdomen) accounts for 18%. If burns involve both arms and the anterior trunk, you add them: 9% + 9% + 18% = 36% of total body surface area. This method provides a quick baseline for initial fluid calculations. If only one arm were burned, the total would be 27% (one arm plus the anterior trunk).
