Using the Parkland formula, how much fluid should be given in the first 8 hours to a 90 kg adult with 50% total body surface area burns? (4 mL x kg x %TBSA in 24 h, half in the first 8 h)
Answer and explanation
Correct answer: D. 9000 mL
- Step 1: Total for 24 h = 4 x 90 x 50 = 18000 mL.
- Step 2: Half is given in the first 8 hours: 9000 mL.
Answer
9000 mL.
Why not the others: 18000 mL is the whole 24-hour volume; the other values use the wrong fraction.
