A nurse is assessing a postmature infant. Which of the following findings would the nurse expect? (Select All that Apply.)

Choice A rationale A positive Moro reflex is a normal neurological reflex observed in newborns and infants, indicating an intact central nervous system. It is present in both term and postmature infants and therefore is not a specific finding that differentiates a postmature infant from a full-term infant. Choice B rationale Vernix caseosa is a white, creamy, naturally occurring biofilm covering the skin of a fetus during the last trimester of pregnancy. Postmature infants, having been in utero for a longer period, typically have little to no vernix, as it is reabsorbed by the amniotic fluid. Choice C rationale Short, soft fingernails are characteristic of term or premature infants. Postmature infants, due to their prolonged gestation, often have long, hard fingernails that may extend past the fingertips, reflecting extended growth in the uterine environment. Choice D rationale Creases covering the soles of the feet are a common finding in postmature infants. The increased maturation of the skin and subcutaneous tissue due to prolonged gestation leads to more prominent and numerous creases on the soles and palms compared to full-term or premature infants. Choice E rationale Cracked, peeling skin is a hallmark characteristic of postmature infants. The prolonged exposure to amniotic fluid after the protective vernix has diminished leads to dehydration and desquamation of the outer layers of the epidermis, resulting in dry, cracked, and peeling skin.
