Final answer:
Using the Parkland formula for a 42% TBSA burn on a 78 kg patient, 13,104 mL of IV fluid is required in 24 hours, with 819 mL/hr to be infused in the first 8 hours.
Step-by-step explanation:
To calculate the rate of IV fluid administration for a burn patient using the Parkland formula, you would use the following equation: 4 mL x patient's weight in kg x percentage of total body surface area (%TBSA) affected by burns. This patient has a burn covering approximately 42 percent of their body and weighs 78 kg. Therefore, the calculation would be 4 mL x 78 kg x 42% = 13,104 mL for the first 24 hours. The Parkland formula also states that half of the total volume should be given in the first 8 hours, and the remaining half over the next 16 hours. To calculate the IV fluid rate for the first 8 hours, divide the total volume for the first half (6,552 mL) by 8 hours, which gives us an IV rate of approximately 819 mL/hr.
