• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

In burn management, TBSA estimation directly drives fluid resuscitation. The amount of fluid given in the initial period is calculated from TBSA burned (often with formulas like 4 mL/kg per %TBSA burned, given over the first 24 hours, with half in the first 8 hours). If you misestimate TBSA by more than about 10%, the calculated fluid volume can be off by a substantial amount, leading to under-resuscitation (risking hypoperfusion and organ injury) or over-resuscitation (risking edema, respiratory failure, and other complications). For a 70 kg patient, a 10% misestimation can alter the 24-hour fluid plan by roughly 2–3 liters, a clinically meaningful difference. That’s why accurate TBSA assessment is essential for safe fluid management. The statement is true.
