A nurse is caring for a 2-day-old newborn who has a bilirubin level of 14 mg/dL (1 to 12 mg/dL) and is to begin phototherapy. Which of the following actions should the nurse take?

Choice A rationale Giving glucose water after feedings is not recommended for newborns undergoing phototherapy for hyperbilirubinemia. Glucose water provides no nutritional benefit, can lead to decreased breast milk intake, and does not aid in the excretion of bilirubin, which is primarily excreted through conjugated bile in stool. Choice B rationale Instructing the client to avoid breastfeeding during treatment for hyperbilirubinemia is incorrect. Breastfeeding should be continued and encouraged, as adequate hydration and caloric intake are crucial for promoting bowel movements, which help in the excretion of bilirubin from the body. Interruption of breastfeeding can also negatively impact milk supply. Choice C rationale Monitoring intake and output is critical for a newborn undergoing phototherapy. Phototherapy can increase insensible fluid losses through the skin, potentially leading to dehydration. Close monitoring of fluid intake (e.g., breastfeeding, formula) and urine/stool output ensures adequate hydration and helps assess the effectiveness of bilirubin excretion. Choice D rationale Applying lotions and ointments throughout phototherapy treatment is contraindicated. These products can absorb the light emitted by the phototherapy unit, leading to potential burns or uneven light distribution on the newborn's skin, thereby reducing the effectiveness of the treatment for hyperbilirubinemia.
