A patient with 45% total body surface area (TBSA) burns and weighing 80 kg requires fluid resuscitation using the Parkland formula. How much fluid should be administered during the first 8 hours?
8,400 mL
7,200 mL
9,600 mL
5,400 mL
The Correct Answer is B
Parkland formula: 4 mL × body weight (kg) × % TBSA = total fluid for 24 hours
Calculation: 4 × 80 × 45 = 14,400 mL in 24 hours
Half of this fluid (14,400 ÷ 2) = 7,200 mL should be administered in the first 8 hours.
The remaining half is given over the next 16 hours.
