According to the Parkland formula, how is fluid resuscitation calculated?

1. 4 mL of Ringer's Lactate x % BSA x kg

2. 3 mL of Normal Saline x % BSA x kg

3. 2 mL of Lactated Ringer's x % BSA x kg

4. 5 mL of D5W x % BSA x kg

The correct answer is: 4 mL of Ringer's Lactate x % BSA x kg

The Parkland formula is specifically designed for calculating fluid resuscitation in burn patients and outlines the recommended amount of fluid to administer in the first 24 hours following a burn injury. The correct approach involves using 4 mL of Ringer's Lactate, multiplying it by the percentage of total body surface area (BSA) that is burned, and then multiplying that result by the patient's weight in kilograms. This formula emphasizes the importance of using Ringer's Lactate, which is preferred in burn resuscitation due to its composition more closely resembling plasma, helping to maintain electrolyte balance. This choice aligns with established guidelines for managing burn injuries and provides a systematic way to address fluid requirements. The other options do not align with the standard Parkland formula guidelines. For instance, using Normal Saline or D5W deviates from the recommended practice as these fluids do not provide the same electrolyte balance that a balanced solution like Lactated Ringer's does. The formula also specifically calls for four, not three or two, milliliters of fluid per BSA percentage and weight, making the correct calculation crucial for optimal patient care.
