The nurse is caring for a newborn born at 30 weeks gestation. Which assessment finding should the nurse anticipate?

Choice A rationale Preterm infants, especially those born at 30 weeks gestation, typically exhibit decreased muscle tone and a lack of physiological flexion. Their extremities often remain extended due to immature neurological development and insufficient muscle tone, contrasting with the full flexion observed in term newborns. Choice B rationale Preterm infants have significantly less subcutaneous fat compared to full-term infants. Adipose tissue accumulation primarily occurs in the third trimester. This lack of insulating fat contributes to their difficulty with thermoregulation and their characteristic thin, scrawny appearance. Choice C rationale Sole creases develop progressively with gestational age, becoming more numerous and prominent as term approaches. A newborn at 30 weeks gestation will have very few, if any, creases on their soles, primarily visible only on the anterior portion of the foot, indicative of their prematurity. Choice D rationale The skin of a 30-week gestation newborn is characteristically smooth, thin, and translucent due to underdeveloped subcutaneous tissue and immature dermal layers. This thinness allows for easy visibility of underlying blood vessels, reflecting their early developmental stage.
