What is a common presenting symptom of kernicterus in neonates?

• A. Severe dehydration
• B. Conjunctivitis
• C. Jaundice
• D. Vomiting

Answer: (C)

Kernicterus is a serious condition that occurs in neonates due to excessive bilirubin levels in the bloodstream, leading to damage in the brain. A common presenting symptom of kernicterus is jaundice, which is characterized by yellowing of the skin and eyes. This occurs because bilirubin—when elevated—deposits in the skin and other tissues. In the context of kernicterus, jaundice often develops within the first week of life and may become more pronounced if biliary obstruction or hemolysis occurs, resulting in higher bilirubin levels. Identifying jaundice early is crucial for prompt intervention to prevent the progression to kernicterus, highlighting its significance as a presenting symptom. Severe dehydration, conjunctivitis, and vomiting, while they may occur in neonates with other conditions, are not characteristic symptoms directly related to kernicterus. In contrast, jaundice is the hallmark symptom that directly indicates the underlying bilirubin levels that may lead to kernicterus if not managed appropriately.
