Final answer:
The fluid resuscitation formula is TBSA% · wt (kg) · 4 mL; for a patient weighing 52 kg with a 30% TBSA burn, this equals 6,240 mL over 24 hours. For the remaining 16 hours, half of this amount, or 3,120 mL, should be administered, which is 3.120 L when converted to liters. None of the options provided in the question correctly matches this volume when considering the last 16 hours only.
Step-by-step explanation:
To calculate fluid resuscitation for burns, the formula TBSA% · wt (kg) · 4 mL is used. In this scenario, a patient weighs 52 kg and has a 30% Total Body Surface Area (TBSA) burn. Using the provided formula:
- TBSA% = 30%
- wt (kg) = 52 kg
- The formula becomes: 30% · 52 kg · 4 mL = 6,240 mL for the initial 24 hours
The formula gives the total volume for the first 24 hours post-burn, and half of this volume is administered in the first 8 hours. Therefore, the volume for the remaining 16 hours is the other half:
6,240 mL / 2 = 3,120 mL for the first 8 hours
Then, 6,240 mL - 3,120 mL = 3,120 mL for the next 16 hours
However, since this is a volume for 16 hours, and the question asks for Lactated Ringer's solution (LRs), we need to convert milliliters to liters using the conversion:
- 1 L = 1,000 mL
- 3,120 mL = 3.120 L (which is the volume to be administered over the last 16 hrs)
This volume falls outside the options provided, which indicates either an error in the question or a misunderstanding of the question's timeframe. If the question intended to ask for the amount to be administered over 24 hours, the volume would be 6,240 mL, which corresponds closely with option A) 6,240 mL, but as the question stands with the 16 hours, none of the options are correct.
