Correct Answer » B Explanation |

The Parkland Formula calculates fluid needs in burn patients:
– Equation: Fluid requirement = 4 mL × weight (kg) × %TBSA burned.
– For this case: 50 kg patient with 40% TBSA (total body surface area) burns.
Step-by-Step Calculation:
1. Apply the formula:
Fluid requirement = 4 × 50 kg × 40 = 8000 mL = 8 liters.
2. Fluid distribution:
– Half (4 liters) given in the first 8 hours.
– Remaining half over the next 16 hours.
Thus, administer 4 liters of Ringer’s lactate in the initial 8 hours.
