A newborn has hyperbilirubinemia and is undergoing phototherapy with a fiberoptic blanket. Which safety measure is most important during this process?

Provide water feedings at least every 2 hours. Protecting the eyes of the neonates is very important to prevent damage when under the ultraviolet lights, but since the blanket is used, extra protection of the eyes is unnecessary. It is recommended that the neonate remain under the lights for extended periods. The neonate's skin is exposed to the light and the temperature is monitored, but a heater may not be necessary. There is no reason to withhold feedings. Frequent water or feedings are given to help with the excretion of the bilirubin in the stool.
