The nurse is preparing a 4-day-old infant with a serum bilirubin level of 19 mg/dl (325 Mcmol/L) for discharge from the hospital. When teaching the parents about home phototherapy, which instruction should the nurse include in the discharge teaching plan?

A. Feeding the infant every 4 hours is important for nutrition but not specifically related to phototherapy. B. Performing diaper changes under the light is important to ensure the effectiveness of phototherapy but repositioning is more crucial for avoiding pressure points and ensuring even exposure to the light. C. Repositioning the infant every 2 hours helps ensure even exposure to the phototherapy light, reducing the risk of complications and maximizing effectiveness. D. Covering the infant with a receiving blanket may interfere with the effectiveness of phototherapy and is not recommended.
