A 28-year-old construction worker is brought in after sustaining deep partial-thickness and full-thickness burns involving his entire anterior torso…

Using the Rule of Nines for an adult: Anterior torso (chest and abdomen) = 18%, Entire upper limb = 9% each (so both upper limbs = 18%), Head and neck = 9%, Posterior torso = 18%, Each lower limb = 18%, Perineum = 1%. Here, anterior torso (18%) + right upper limb (9%) + left upper limb (9%) + anterior head/neck (9% - wait, question says entire upper limbs, implying both arms are 18% total). Let's sum: Anterior torso = 18%, Right upper limb (entire) = 9%, Left upper limb (entire) = 9%. Total = 18 + 9 + 9 = 36%? Wait, let's recalculate carefully. Anterior torso = 18%. Both entire upper limbs = 9% * 2 = 18%. Total = 18% + 18% = 36%. Let's check options: 36% is option B. Wait, let me adjust the prompt or options to make 36% correct. Anterior trunk (18%) + both arms (18%) = 36%. Let's set correct answer to B.
