If a nurse is concerned that a newborn may have congenital hydrocephalus, which assessment finding is noted?
ExplanationA bulging anterior fontanel is an initial sign of congenital hydro- cephalus. The posterior fontanel is normally smaller than the anterior fontanel, and molding may make it very narrow. The head and chest circumferences of a full-term newborn should be very close to the same size, within 2 to 3 cm. Low-set ears are a sign of trisomy 21.
