A 7-year-old boy weighing 22 kg is admitted in emergency with 50% burn. How much fluid should be infused within the first 8 hours?

Appeared in: IGIMS Staff Nurse - 2018

Explanation

The Parkland formula is the standard guideline for calculating initial fluid requirements in burn patients.
The formula calculates the total fluid needed for the first 24 hours: 4 mL × Body Weight (kg) × % TBSA.
For this patient, the calculation is: 4 mL × 22 kg × 50 = 4400 mL.
According to the formula's administration schedule, half of this total volume (4400 mL / 2) must be infused over the first 8 hours from the time of the burn.
Therefore, the correct volume for the first 8 hours is 2200 mL.

Option A: This value is an underestimation of the required fluid volume. It may result from using an incorrect multiplier (e.g., less than 4 mL/kg) or miscalculating the total volume.
Option C: This value is an overestimation. It does not correspond to the correct calculation using the standard Parkland formula.
Option D: This value is a significant overestimation and does not align with the Parkland formula calculation.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Fluid resuscitation calculation for pediatric burn patients using the Parkland formula as background academic context rather than a clinical decision trigger.
Accurate fluid resuscitation is the cornerstone of early burn management to prevent burn shock, a life-threatening distributive shock caused by massive fluid shifts from the intravascular to the extravascular space.
Nurses play a critical role in titrating IV fluids based on the patient's response, primarily by monitoring hourly urine output to ensure adequate organ perfusion without causing fluid overload.
Under-resuscitation can lead to acute kidney injury and organ failure, while over-resuscitation increases the risk of pulmonary edema and abdominal or extremity compartment syndrome.

How to Approach the Question

First, identify that this is a calculation question requiring a specific formula.
Identify the key patient data provided in the stem: weight (22 kg) and Total Body Surface Area burn percentage (50%).
Recall the standard formula for fluid resuscitation in burn patients: the Parkland formula.
State the formula: Total Fluid for 24 hours = 4 mL × Body Weight (kg) × % TBSA.
Substitute the patient's values into the formula: 4 × 22 × 50.
Calculate the total fluid volume needed for 24 hours.

Concept Tested & Keywords

Concept Tested: Fluid resuscitation calculation for pediatric burn patients using the Parkland formula.
Stem keywords: 7-year-old boy, 22 kg, 50% burn, first 8 hours
Lead-in keywords: How much fluid
Clinical cues: Patient is a child (7 years old, 22 kg), which requires pediatric-specific considerations for fluid management.
Clinical cues: The burn is extensive (50%), indicating a major burn that requires aggressive fluid resuscitation to prevent shock.
