ABSTRACT
A1 C Newborns are classified based on gestational age and weight. Pre-term infants are those born before 37 weeks of gestation. Term infants are those born between 37 and 42 weeks of gestation, whereas post-term infants have a gestation that exceeds 42 weeks. Newborns with weight at or above the 90th percentile are LGA and those below the 10th percentile are SGA. Newborns whose weight falls between these extremes are appropriate for gestational age. Infants born before 37 weeks of gestation, regardless of birthweight, are considered premature. A premature infant has thin and transparent skin with an absence of plantar creases, soft malleable fingers, and ears with poorly developed cartilage. In females, the labia minora appear enlarged and the labia majora appear small. In males, the testes are usually undescended and the scrotum is underdeveloped.
