Explanation

The Holliday-Segar method calculates daily maintenance fluid requirements in children based on weight.
For a 20 kg child, the calculation is broken into two parts: the first 10 kg and the next 10 kg.
First 10 kg: 10 kg × 100 mL/kg = 1000 mL.
Next 10 kg (from 11 to 20 kg): 10 kg × 50 mL/kg = 500 mL.
Total daily fluid requirement is the sum of these two parts: 1000 mL + 500 mL = 1500 mL.

Option A: This only accounts for the fluid requirement for the first 10 kg of body weight (10 kg x 100 mL/kg).
Option B: This is an incorrect calculation. It might result from misapplying the formula, for example, using an incorrect multiplier for the second 10 kg.
Option D: This is an incorrect calculation. It overestimates the fluid needs and could lead to fluid overload.

Clinical Relevance

Nursing practice connection: Use the key finding related to Pediatric maintenance fluid calculation using the Holliday-Segar method to guide bedside assessment, documentation, and the next nursing action.
Accurate calculation of maintenance fluids is critical in pediatric nursing to prevent dehydration or iatrogenic fluid overload, both of which can have severe consequences in children due to their smaller body size and immature organ systems.
Nurses frequently use this formula to set IV infusion pump rates and monitor a child's fluid balance (intake and output). An error in calculation can lead to significant harm.
What if the child had a fever? Fever increases metabolic rate and insensible water loss. The maintenance fluid rate would need to be increased, typically by 10-12% for each degree Celsius above 38°C, requiring a recalculation and adjustment of the infusion.

How to Approach the Question

Identify the core task: The question asks for a calculation of daily maintenance fluid for a child of a specific weight.
Recall the relevant formula: The Holliday-Segar method (100-50-20 rule) is the standard for this calculation.
Break down the child's weight (20 kg) into the formula's tiers: the first 10 kg and the second 10 kg.
Calculate the fluid for the first tier: 10 kg × 100 mL/kg = 1000 mL.
Calculate the fluid for the second tier: 10 kg × 50 mL/kg = 500 mL.
Sum the amounts from all tiers to find the total daily requirement: 1000 mL + 500 mL = 1500 mL. Then, match the result to the given options.
