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. The nurse's best response is:

"Your baby may lose heat by convection, which means that he will lose heat from his body to the cooler ambient air.

You should keep him wrapped and prevent cool air from blowing on him.”.

"Your baby may lose heat by conduction, which means that he will lose heat from his body to a cooler surface with which he is in direct contact.”.

"Your baby may lose heat by evaporation, which means that he will lose heat from his body as water vaporizes from his skin.”.
