Final answer:
In a child with meningitis receiving I.V. fluids, a nurse should prioritize monitoring for cerebral edema to manage complications early and maintain neurological function.
Step-by-step explanation:
To detect complications as early as possible in a child with meningitis who's receiving I.V. fluids, monitoring for cerebral edema should be the nurse's priority. Complications of meningitis can be swift and severe due to the inflammation of the meninges, which can affect neurological function dramatically. Cerebral edema is a critical complication because it can lead to increased intracranial pressure, herniation, and it directly affects the brain tissue. Monitoring for cerebral edema would help in managing intracranial pressure and ensuring the cerebral perfusion is maintained.
