State the Parkland formula for estimating fluid resuscitation in burn patients and the administration timing.

• A. 4 mL x body weight (kg) x %TBSA burned in the first 24 hours; half in the first 8 hours from time of burn, the remaining half over the next 16 hours (adjust for urine output).
• B. 5 mL x body weight x %TBSA burned in the first 24 hours; half in the first 12 hours, rest over 12 hours.
• C. 3 mL x body weight x %TBSA burned; distribute evenly over 24 hours.
• D. 4 mL x body weight x %TBSA burned in the first 48 hours; all in first 24 hours.

Answer: (A)

The main idea here is how burn resuscitation is guided to restore circulating volume after a significant injury. The Parkland formula says to give a total of 4 mL per kilogram of body weight for each percent of TBSA burned, all within the first 24 hours. But you don’t dump it all at once: half of that total is given in the first 8 hours from the time of burn, and the remaining half is given over the next 16 hours. The fluid is typically Lactated Ringer’s, and the rate is adjusted based on how well the patient is producing urine, with the goal of adequate perfusion. This pattern addresses the dramatic capillary leak and fluid shifts that occur after burns, aiming to prevent hypovolemia and shock early on. So, the correct approach matches this exact timing and calculation: 4 mL × body weight in kg × %TBSA burned over 24 hours, with half in the first 8 hours and the rest over the next 16 hours, guided by urine output. The other patterns use different multipliers or different time splits and don’t align with the Parkland protocol.
