Body Surface Area Estimation in Burns

A 6-year-old child is admitted with 30% BSA thermal burns following a house fire. The attending physician needs to estimate the exact percentage of body surface area to calculate fluid requirements accurately. Which investigation would be most appropriate to account for the child's age-specific body proportions?

A 32-year-old man sustains a thermal burn to his entire right upper limb and anterior trunk. Which feature best distinguishes the Rule of Nines estimation of total body surface area (TBSA) from the Lund and Browder chart in this clinical scenario?

A 4-year-old child is admitted with 35% TBSA burns following a house fire. When comparing the Rule of Nines with the Lund and Browder chart for this patient, which finding would most clearly demonstrate why Lund and Browder is preferred in paediatric burn assessment?

A 28-year-old woman is admitted to the burn unit following a house fire. On examination, she has full-thickness burns over the entire posterior trunk (back and buttocks), both posterior lower limbs, and the posterior aspect of both upper limbs. Using the Rule of Nines, what is the total percentage of BSA affected by this burn injury?

According to the Rule of Nines, what percentage of body surface area is represented by the head and neck in an adult?
