A nurse on a mental health unit is admitting a client. Exhibits Select the 3 client findings the nurse should recognize as manifestations of water intoxication.

A. Activity level: Restlessness, pacing, and inability to remain seated are early neurological manifestations of water intoxication, stemming from cerebral edema related to hyponatremia. These signs often precede more severe symptoms like seizures. B. White blood cell count: A count of 9,100/mm³ is within normal limits and does not indicate water intoxication. This value is unrelated to the dilutional effects of excessive fluid intake. C. Sodium level: A sodium of 130 mEq/L indicates hyponatremia, which is a hallmark laboratory finding in water intoxication due to dilutional effects from excess fluid intake. Low sodium can cause neurological changes and altered mental status. D. Potassium level: A potassium of 3.6 mEq/L is within the normal range and does not support a diagnosis of water intoxication. Potassium is less affected by acute overhydration compared to sodium. E. Hallucinations: Responding to unseen stimuli can occur when hyponatremia causes cerebral swelling, disrupting normal brain function. In clients with psychotic disorders, excess water intake can exacerbate hallucinations or make them more pronounced.
