A newborn is jaundiced and receiving phototherapy via ultraviolet bank lights.An appropriate nursing intervention when caring for an infant with hyperbilirubinemia and receiving phototherapy by this method would be to:

Choice A rationaleLimiting the newborn's intake of milk is contraindicated in the treatment of hyperbilirubinemia. Adequate hydration and frequent feedings are essential to promote bilirubin excretion through stool and urine. Decreased intake can exacerbate dehydration and worsen jaundice. Normal feeding frequency for newborns is typically every 2-3 hours.Choice B rationaleFeeding the newborn every six hours is not an appropriate intervention for a jaundiced infant receiving phototherapy. Frequent feedings, typically every 2-3 hours, are necessary to promote bilirubin excretion. Prolonged intervals between feedings can lead to dehydration and hinder the effectiveness of phototherapy.Choice C rationaleTurning the infant every two hours is a crucial nursing intervention during phototherapy. This ensures that all body surfaces are exposed to the ultraviolet light, maximizing the breakdown of bilirubin in the skin. Consistent exposure of all areas helps to lower bilirubin levels more effectively.Choice D rationaleApplying an oil-based lotion to the newborn's skin during phototherapy is contraindicated. Oil-based lotions can create a barrier on the skin, reducing the penetration and effectiveness of the ultraviolet light. Only water-based lotions, if necessary, should be used sparingly and with caution, as some may absorb UV light.
