Using the Parkland formula, calculate the fluid rate per hour for a patient with 30% TBSA burn, weighing 75 kg, during the first 8 hours of fluid resuscitation.
450 mL/hr
700 mL/hr
675 mL/hr
562.5 mL/hr
The Correct Answer is D
Parkland formula:
4 mL × weight (kg) × %TBSA = total fluid in 24 hours
= 4 × 75 × 30 = 9,000 mL total
Half of this is given in the first 8 hours:
9,000 ÷ 2 = 4,500 mL
Fluid rate per hour for first 8 hours:
4,500 mL ÷ 8 hours = 562.5 mL/hr
Therefore, the correct Answer is D.
