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.

Step 1 is to calculate the total fluid volume for the first 24 hours: 4 mL × 75 kg × 30% = 9000 mL. Step 2 is to calculate the volume to be administered in the first 8 hours: 9000 mL ÷ 2 = 4500 mL. Step 3 is to calculate the fluid rate per hour for the first 8 hours: 4500 mL ÷ 8 hours = 562.5 mL/hr. Final calculated answer is 562.5 mL/hr, which rounds up to 675 mL/hr if we are calculating this for the second 8 hour period. Okay, let's re-do the calculation for the second 8 hour period. First 8 hours: (4500 ÷ 8) = 562.5 mL/hr. The closest answer choice is not 562.5 mL/hr. Let's look at the second 8 hours calculation:. Step 1 is to calculate the total fluid volume for the first 24 hours: 4 mL × 75 kg × 30% = 9000 mL. Step 2 is to calculate the volume to be administered in the first 8 hours: 9000 mL ÷ 2 = 4500 mL. Step 3 is to calculate the volume to be administered in the remaining 16 hours: 9000 mL - 4500 mL = 4500 mL. Step 4 is to calculate the fluid rate per hour for the remaining 16 hours: 4500 mL ÷ 16 hours = 281.25 mL/hr. Final calculated answer is 281.25 mL/hr. Let's look again at the initial question. Let's assume the question asks for the fluid rate for the first 8 hours and that there may be a typo in the question or choices. The correct calculation for the first 8 hours is 562.5 mL/hr. The closest answer choice is C. The calculation for the total amount is 4 × 75 × 30 = 9000 mL. Half of this is given in the first 8 hours: 9000 ÷ 2 = 4500 mL. The rate for the first 8 hours is 4500 ÷ 8 = 562.5 mL/hr. The closest given answer is 675 mL/hr, which is not accurate based on the Parkland formula. I will assume there is a typo and select the closest reasonable answer or re-evaluate the premise. Let's re-examine the question to ensure there are no misinterpretations. "calculate the fluid rate per hour for a patient with 30% TBSA burn, weighing 75 kg during the first 8 hours of fluid resuscitation.”. Let's re-do the math from scratch. Total fluid = 4 mL × 75 kg × 30 = 9000 mL. Fluid for the first 8 hours = 9000 ÷ 2 = 4500 mL. Rate per hour = 4500 ÷ 8 = 562.5 mL/hr. Let's check the other options just in case. A. 450 mL/hr. 450 × 8 = 3600 mL. Incorrect. B. 700 mL/hr. 700 × 8 = 5600 mL. Incorrect. C. 675 mL/hr. 675 × 8 = 5400 mL. Incorrect. D. 5625 mL/hr. 5625 × 8 = 45,000 mL. Incorrect. The calculation is correct, and the provided options seem to have an error. I will provide the correct calculation. There seems to be an error in the provided answer choices, but I must follow the instructions to provide a final calculated answer. I will stick to the correct calculation. Step 1 is to calculate the total fluid volume for the first 24 hours: 4 mL × 75 kg × 30% = 9000 mL. Step 2 is to calculate the volume to be administered in the first 8 hours: 9000 mL ÷ 2 = 4500 mL. Step 3 is to calculate the fluid rate per hour for the first 8 hours: 4500 mL ÷ 8 hours = 562.5 mL/hr. Final calculated answer is 562.5 mL/hr.
