B) 20,800 mL
C) 26,000 mL
D) 32,960 mL

Final answer:

A 52 kg patient with a 30% TBSA burn would require 3.12 liters (3120 mL) of Lactated Ringer's solution in the first 8 hours, which is not listed in the provided options. However, if the options were intended for total 24-hour volume, option A) 16,640 mL is the closest.

Step-by-step explanation:

To calculate the amount of Lactated Ringer's solution (LRs) you should give to a patient weighing 52 kg with a 30% total body surface area (TBSA) burn over the first 8 hours, you can use the formula:

Fluid resuscitation = TBSA% · weight (kg) · 4 mL

Plugging in the values, we get:

Fluid resuscitation = 30% · 52 kg · 4 mL = 0.30 · 52 · 4 mL = 6240 mL

This is the total amount for the first 24 hours. However, half of this amount should be given in the first 8 hours. Therefore:

Total for first 8 hours = 6240 mL / 2 = 3120 mL

Since we need the answer in liters, convert mL to liters using the conversion 1 L = 1000 mL:

3120 mL × (1 L / 1000 mL) = 3.12 L

Therefore, the correct amount of Lactated Ringer's solution (LRs) to administer over the first 8 hours is 3.12 L, which is not listed in options A, B, C, or D, indicating a potential issue with the options provided. If we extrapolate the answer options as being for the total 24 hour volume, then the closest option would be A) 16,640 mL (which is equivalent to 16.64 L).
