For a 2-day-old newborn with a bilirubin level of 14 mg/dL starting phototherapy, what should the nurse monitor?

In the context of a 2-day-old newborn undergoing phototherapy for elevated bilirubin levels, monitoring intake and output is crucial. The primary goal of phototherapy is to reduce bilirubin levels by promoting its excretion through the liver and kidneys. Adequate hydration is essential to support this process and ensure that the baby can effectively eliminate bilirubin via urine and stool.

Additionally, whole-body phototherapy can lead to increased fluid losses due to exposure to light, which may cause dehydration if fluid intake is not sufficient. By carefully monitoring intake and output, the nurse can assess the newborn’s hydration status and ensure that the baby is receiving enough fluids to facilitate the excretion of bilirubin.

While vital signs, skin integrity, and blood glucose levels are important aspects of a newborn's care, in this specific scenario, focusing on intake and output directly addresses the risks associated with phototherapy and the management of elevated bilirubin levels.
