What bilirubin level indicates severe hyperbilirubinemia in newborns?

• A. 10-15 mg/dL
• B. 15-20 mg/dL
• C. > 25-30 mg/dL
• D. 30-35 mg/dL

Answer: (C)

Severe hyperbilirubinemia in newborns is typically defined as a serum bilirubin level exceeding 25 mg/dL. At this level, there is a significant risk of bilirubin-induced neurologic dysfunction, including kernicterus, which can have serious long-term consequences. Monitoring bilirubin levels is crucial in managing newborns, especially those at risk for jaundice, as early identification and intervention can prevent complications.

Therefore, the identification of levels greater than 25-30 mg/dL as severe hyperbilirubinemia aligns with established clinical guidelines and recommendations for the management of newborn jaundice. Continuous monitoring and appropriate clinical response at this threshold are essential to ensure the safety and health of the newborn.
