**Question:** 24 hour normal fluid requirement for a one year old child weighing 8 kg is

A. 750 ml
B. 1000 ml
C. 1200 ml
D. 1500 ml

**Core Concept:** Fluid and Electrolyte Balance in Pediatrics

**Why the Correct Answer is Right:**

The correct answer is **1200 ml** (Option C). A one-year-old child weighing 8 kg has a high water requirement due to rapid growth, increased urine production, and high body surface area to volume ratio. The kidneys of young children are not yet fully developed and are unable to concentrate urine efficiently. Consequently, they require more fluid to maintain proper hydration and electrolyte balance.

**Why Each Wrong Option is Incorrect:**

A. **750 ml (Option A)** is too low as it does not account for the child's increased fluid requirements and immature renal function.
B. **1000 ml (Option B)** is still too low as it does not reflect the high water requirement of a rapidly growing child.
D. **1500 ml (Option D)** is too high for a one-year-old, considering their immature renal function and relatively lower body weight compared to adults.

**Why Option C is Correct:**

Fluid requirements for a one-year-old child are influenced by factors such as age, weight, and body surface area. The correct answer, 1200 ml, represents a balance between the child's increased water needs and their immature renal function.

**Clinical Pearl:**

In pediatrics, it is essential to consider factors like renal immaturity when determining fluid requirements, especially in infants and young children. Monitoring fluid intake and output is crucial to ensure proper hydration and electrolyte balance in pediatric patients.
