A client is warm and asks for a fan in her room for her comfort.The nurse enters the room to assess the mother and her infant and finds the infant unwrapped in his crib with the fan blowing over him on high.The nurse instructs the mother that the fan should not be directed toward the newborn and that the newborn should be wrapped in a blanket.The mother asks why.How would the nurse respond?

The healthy infant must accomplish both behavioral and biologic tasks to develop normally. Behavioral characteristics form the basis of the social capabilities of the infant. Newborns pass through a hierarchy of developmental challenges as they adapt to their environment and caregivers. This progression in behavior is the basis for the Brazelton Neonatal Behavioral Assessment (NBAS). Match the cluster of neonatal behaviors with the correct level on the NBAS scale. -Signs of stress related to homeostatic adjustment
