Which statement reflects meconium timing for term infants compared with very low birth weight infants?

• A. Term infants: 24-48 hours; Very low birth weight: may be delayed up to 7 days.
• B. Term infants: immediately at birth; Very low birth weight: never delayed.
• C. Term infants: after 1 week; Very low birth weight: within 12 hours.
• D. Term infants: only after feeding begins; Very low birth weight: after 2 weeks.

Answer: (A)

Meconium timing reflects GI maturity and motility. Term newborns typically pass meconium within the first 24 to 48 hours after birth, while very low birth weight infants often have immature gut function that can delay stool passage, with delays as long as about a week being possible. So, describing term infants as 24–48 hours and very low birth weight infants as potentially delayed up to 7 days best captures the usual pattern. Other statements imply immediate passage, no delay, or much longer delays for term infants, which don’t fit the typical physiology of term versus very low birth weight neonates.
