Which category describes an infant born before 28 weeks of gestation?

• A. Very preterm
• B. Late preterm
• C. Moderate preterm
• D. Extremely preterm

Answer: (D)

The category that describes an infant born before 28 weeks of gestation is extremely preterm. This classification is utilized within neonatology to define the gestational age of preterm infants. Infants born in this range face significant risks for various complications due to their underdeveloped organs and systems, necessitating specialized medical care.

Understanding gestational age categories is crucial in perinatal care, as these distinctions help inform the expected management and intervention strategies for newborns. Infants classified as very preterm, for instance, are those born between 28 and less than 32 weeks, while late preterm infants are those born between 34 and less than 37 weeks. Moderate preterm is a less commonly used classification that generally refers to those born between 32 and less than 34 weeks. The definitional clarity within these categories plays a vital role in assessing and responding to the specific needs of preterm infants.
