What is a key measure in the care plan for a newborn diagnosed with hyperbilirubinemia who is about to undergo phototherapy?

In the care plan for a newborn diagnosed with hyperbilirubinemia undergoing phototherapy, ensuring the infant is well-hydrated is crucial. Phototherapy can lead to increased fluid losses through the skin, so maintaining adequate hydration helps support the infant's overall health and promotes effective bilirubin elimination. Hydration aids in renal function, ensuring that the kidneys can effectively filter and excrete bilirubin from the bloodstream.

While monitoring temperature, controlling light exposure, and providing frequent feedings are important aspects of the care for a newborn, focusing specifically on hydration addresses one of the key physiological changes occurring during phototherapy. Keeping the infant hydrated minimizes the risk of complications and reinforces the treatment's effectiveness by facilitating the metabolic processes involved in the breakdown of bilirubin.
