A client with hydrocephalus reports having had a headache in the morning on arising for the last 3days,but it disappears later in the day.The nurse should:
1.Notify the physician.
2.Tell the client that this is normal because intracranial pressure (ICP) fluctuates throughout the day.
3.Instruct the client to increase fluid intake prior to going to bed to prevent headache in the morning.
4.Advise the client to request pain medication from the physician.
