A newborn weighs 2 kg at birth. How much fluid intake is required on the first and third day?

Correct option is D

Ans. (d) Sol. Fluid requirements for newborns are calculated based on gestational age, weight, and postnatal age. The general fluid intake guidelines for preterm and low-birth-weight infants (like a 2 kg newborn) are as follows:
· Day 1: 60 ml/kg/day
· Day 3: 100 ml/kg/day
Thus, for a 2 kg newborn:
· Day 1 fluid requirement = 60 ml × 2 kg = 120 ml/day
· Day 3 fluid requirement = 100 ml × 2 kg = 200 ml/day
This ensures proper hydration, thermoregulation, and metabolic needs while preventing fluid overload in newborns.
Explanation of Other Options:
· (a) 40 ml/kg/day and 50 ml/kg/day: Too low for a newborn’s metabolic demands and may lead to dehydration.
· (b) 80 ml/kg/day and 120 ml/kg/day: Slightly higher than the recommended fluid requirement on Day 1 but still acceptable for some cases.
· (c) 50 ml/kg/day and 70 ml/kg/day: Insufficient for optimal hydration and growth.
