A nurse is caring for a newborn who is receiving phototherapy treatment. Which of the following actions should the nurse take?

A. Place the newborn in the prone position: The supine position is recommended for newborns to reduce the risk of sudden infant death syndrome (SIDS). Phototherapy does not change this guideline, and the baby should be placed on their back. B. Offer glucose water after each feeding: Glucose water is not recommended as a supplement. Breast milk or formula provides sufficient nutrition and hydration. The focus should be on maintaining regular feedings to support bilirubin excretion. C. Apply lotion to the newborn's exposed skin: Lotions and ointments should be avoided during phototherapy because they can cause skin irritation or even burns when exposed to the phototherapy lights. D. Cover the newborn's eyes with a mask: The eyes must be protected during phototherapy to prevent retinal damage from the intense light exposure. A properly fitted eye mask should be used and checked regularly for correct placement.
