Which finding is a normal sign of a preterm newborn?

• A. Deep Creases On Soles Of Feet
• B. Peeling Of Skin
• C. Abundant Lanugo
• D. Palpable Breast Buds

Answer: (C)

Lanugo indicates how far along in gestation the baby developed. In preterm newborns, there is abundant lanugo—the fine, downy hair covers much of the body because the fetus hasn’t yet shed it as maturation progresses. As gestational age increases, lanugo diminishes and is often minimal or absent by term. So finding abundant lanugo is a normal sign pointing to prematurity.

Deep creases on the soles, peeling skin, or prominent breast buds are tied to different stages of maturation. Deep plantar creases and peeling skin are more typical of term or post-term infants, reflecting more mature skin and bodily changes. Breast buds can be present due to maternal hormones in newborns of various gestational ages, so they’re not as specific to prematurity.
