According to the Wallace 'Rule of Nines', what is the total body surface area (TBSA%) burned in an adult with burns to the entire right arm and the anterior trunk?

  • A 27%
  • B 27%
  • C 27%
  • D 36%
Correct answer: C. 27%

Explanation

By the Rule of Nines in adults: each arm = 9%, anterior trunk = 18%. Right arm (9%) + anterior trunk (18%) = 27% TBSA burned. The Parkland formula (4 mL × weight in kg × %TBSA burned) would then guide resuscitation fluid requirements. This is a conceptual calculation verifying the rule-of-nines assignment for these body areas.
