Rationale: Postoperative nursing care for an infant with hydrocephalus who underwent ventriculoperitoneal shunt placement includes monitoring closely for signs of infection, as infection is the greatest hazard in the postoperative period. Signs of cerebrospinal fluid infection to watch for include elevated temperature, poor feeding, vomiting, decreased responsiveness, and seizure activity. The child should be placed with the operative side of the head up to reduce pressure on the valve. The shunt reservoir should not be pumped to maintain patency, as this can disrupt its function. Maintaining a Trendelenburg position to decrease pressure on the shunt is contraindicated as it can lead to increased intracranial pressure and compromise the shunt's effectiveness.
