General Surgery · Burns

Sample item

A 70 kg adult has burns over 40% of the body surface. By the Parkland formula, what total volume of Ringer's lactate is needed in the first 24 hours?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. 11,200 mL

Parkland: 4 mL × weight (kg) × %TBSA = 4 × 70 × 40 = 11,200 mL. Half is given in the first 8 hours from the time of burn and the rest over the next 16 hours, then titrated to urine output.

Option by option

  • A. 2,800 mL

    2,800 mL uses only 1 mL/kg/%, which is far too low.

  • B. 11,200 mL (correct)

    Correct.

  • C. 5,600 mL

    5,600 mL is half of the total, given in the first 8 hours.

  • D. 8,400 mL

    8,400 mL would be 3 mL/kg/%.
