A 45-yrs-old firefighter who weights 74 kg sustains a third-degree burn to 64 percent of his total body surface area. The patient arrives in the emergency depament approximately 30 min after the time of the accident. When the patient’s intravenous fluid requirements are calculated using the Parkland formula, the initial orders for choice of fluid and rate of infusion should be

**Core Concept**
The Parkland formula is used to calculate the total amount of fluid required for the first 24 hours in a patient with burns, taking into account the percentage of the body surface area burned. The formula is: total fluid (in mL) = 4 mL × weight (in kg) × % of total body surface area burned.

**Why the Correct Answer is Right**
The Parkland formula calculates the fluid needs for the first 24 hours, with half of the calculated volume administered in the first 8 hours and the remaining half in the subsequent 16 hours. The choice of fluid is typically lactated Ringer's solution. For a 74 kg patient with 64% burns, the calculation would be: 4 mL × 74 kg × 64 = 18,944 mL. Half of this volume (9,472 mL) should be given in the first 8 hours.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because the choice of fluid and rate of infusion do not match the Parkland formula's recommendations.
**Option B:** Incorrect as it does not align with the calculated fluid volume based on the Parkland formula.
**Option C:** Incorrect because it does not specify the correct fluid type and infusion rate according to the Parkland formula.
**Option D:** Incorrect as the details provided do not correspond with the standard application of the Parkland formula for burn patients.

**Clinical Pearl / High-Yield Fact**
The Parkland formula is crucial for managing burn patients, as it helps prevent hypovolemia and organ failure by ensuring adequate fluid resuscitation. Remember, the formula provides the total fluid for the first 24 hours, with half given in the first 8 hours.

**Correct Answer:** D. Lactated Ringer’s solution at a rate of 198 mL/hr for the first 8 hours.

✓ Correct Answer: B. Ringer's lactate, 1250 ml/h for 1/2h
