Which weight range is specified for term neonates when determining the 2 mcg/kg/day selenium dose?

• A. 0-1 kg
• B. 2-5 kg
• C. 3-10 kg
• D. 11-20 kg

Answer: (C)

In neonatal parenteral nutrition, trace element dosing is organized into weight-based bands so the amount given per day scales with the infant’s size. For term neonates receiving 2 mcg/kg/day of selenium, the guideline uses the 3-10 kg weight range. This band reflects typical term neonate and early infant weights where this fixed per-kilogram dose is appropriate. Smaller infants (0-1 kg) or mid-range neonates (2-5 kg) fall into different dosing tables, while much heavier infants (11-20 kg) are outside the neonatal range and would use other guidelines. To see how it works in practice, multiply the baby’s weight by 2 mcg/kg/day. For example, a 4 kg term neonate would receive about 8 mcg of selenium daily.
