Final answer:
To address hypothermia in a preterm neonate, the nurse should gradually rewarm the infant, notify the practitioner, and record skin temperature hourly.
Step-by-step explanation:
When dealing with a preterm neonate experiencing hypothermia, the nurse should take immediate action to mitigate the situation. The correct action for the nurse to take is to rewarm the infant gradually by using skin-to-skin contact, warm blankets, or a radiant warmer. This helps to normalize the baby's body temperature and prevent further heat loss.
In addition to rewarming, the nurse should also notify the practitioner or the healthcare team. They need to be made aware of the infant's hypothermia so that appropriate interventions can be initiated.
Recording the skin temperature hourly is important to closely monitor the infant's condition and track progress in maintaining normal body temperature.
