Final answer:
The clinical manifestations that may indicate hydrocephaly in an infant include depressed fontanel, irritability, bulging fontanel, and vomiting.
Step-by-step explanation:
The clinical manifestations that would lead the nurse to suspect an infant has hydrocephaly are:
- Depressed fontanel
- Irritability
- Bulging fontanel
- Vomiting
Hydrocephaly is a condition characterized by the accumulation of excess cerebrospinal fluid in the brain, leading to enlargement of the ventricles and increased intracranial pressure. The depressed fontanel occurs when there is insufficient fluid in the brain to support normal brain growth and development. Irritability can result from increased pressure on the brain, while bulging fontanel is a classic sign of increased intracranial pressure. Vomiting is also commonly seen due to the pressure on the brainstem, which controls nausea and vomiting reflexes.
