A nurse is assessing a newborn immediately following a vaginal birth. For which of the following findings should the nurse intervene?

Choice A rationale Sternal retractions indicate increased respiratory effort and can be a sign of respiratory distress in a newborn. This occurs when the infant is struggling to inhale, causing the chest wall to visibly pull inward with each breath due to negative pressure, and requires immediate intervention. Choice B rationale Acrocyanosis, characterized by bluish discoloration of the hands and feet, is a common and normal finding in newborns during the first 24 to 48 hours after birth. It is due to immature peripheral circulation and does not typically indicate a need for intervention. Choice C rationale Molding is the overlapping of the fetal skull bones during passage through the birth canal. This is a normal adaptation during vaginal birth and typically resolves spontaneously within a few days, thus requiring no intervention. Choice D rationale Vernix caseosa is a whitish, cheesy substance covering the skin of many newborns, providing protection and lubrication in utero. Its presence is normal and beneficial, often providing hydration and antimicrobial properties to the skin post-birth.
