Define the age range for neonates.

• A. 0-1 months
• B. 1-2 weeks
• C. 0-3 months
• D. 2-4 weeks

Answer: (A)

Neonates are defined as the first 28 days after birth. This is normally described as birth through about four weeks, roughly 0-1 month. So the range from birth to about 28 days best matches the neonatal period. The other options either start after birth, extend beyond the neonatal window, or cover only part of the neonatal time frame. For instance, a period that begins after birth misses those initial days; a period that goes up to 0-3 months includes infants beyond the neonatal stage; and a window limited to 2-4 weeks misses the early birth days.
