A 28-year-old woman with 45% TBSA deep partial-thickness and full-thickness burns is started on the Parkland formula. She weighs 60 kg. The total fluid requirement in the first 24 hours (in mL) and the volume to be given in the first 8 hours are, respectively:

• A 10,800 mL total; 5,400 mL in first 8 hours ✓
• B 10,800 mL total; 2,700 mL in first 8 hours
• C 5,400 mL total; 2,700 mL in first 8 hours
• D 7,200 mL total; 3,600 mL in first 8 hours

Explanation

Parkland formula: 4 mL × body weight (kg) × %TBSA = 4 × 60 × 45 = 10,800 mL of Ringer's lactate in 24 hours. Half (5,400 mL) is given in the first 8 hours from the time of injury (not admission), and the remaining half over the next 16 hours. Colloid is not given in the first 24 hours with the Parkland formula. Option C incorrectly halves the total volume; Option D applies a coefficient of 4 × 60 × 30 = 7,200, not 45% TBSA.
