When they drink too much. Nursing interventions for patients with disordered water balance.

Disordered water balance affects as many as 60% of severely psychiatrically disabled persons. Most patients do not progress to the point of a medical emergency, but are in a state of mild chronic intoxication, making them unavailable for treatment and requiring nursing care to treat the effects of the chronic intoxicated state. Interventions depend on the severity of the disordered water balance and vary from teaching fluid intake control to controlling all patient access to fluids. Nursing management of water intoxication is a trial and error approach. Through a thorough assessment and close observation of the patient, the nurse can determine which interventions would be most appropriate for the patient.
