<prompt> Burn involving one lower limbs in adult correspondence to area:4.50913.5018  <response>: Ans: D 18 Determination of Burn Size Sabiston 19th523 Burn size is generally assessed by the so-called rule of nines . In adults, each upper extremity and the head and neck are 9 of TBSA, the lower extremities and the anterior and posterior aspects of the trunk are 18 each, and the perineum and genitalia are assumed to be 1 of TBSA. Another method of estimating smaller burns is to consider the area of the open hand including the palm and extended fingers of the patient to be approximately 1 of TBSA and then transpose that measurement visually onto the wound for a determination of its size. This method is helpful when evaluating splash burns and other bums of mixed distribution.
