A nurse is providing care for an older adult client who has diabetes insipidus (DI). The nurse should monitor the client for which of the following neurologic effects?

A. Dilute urine: In diabetes insipidus the kidneys are unable to concentrate urine, leading to the excretion of dilute urine. While this is a characteristic of DI, it is not specifically a neurologic effect. B. Poor skin turgor: Poor skin turgor is a sign of dehydration, which can occur in DI due to excessive urine output. It is a physical finding related to fluid balance rather than a neurologic effect, though it should still be monitored as part of overall care. C. Hypotension: Hypotension can occur as a result of dehydration due to fluid loss in DI. While this can be a concern, it is a cardiovascular issue rather than a neurologic effect. Monitoring blood pressure is important but it does not address neurologic complications. D. Ataxia: Ataxia is a neurologic symptom that can result from dehydration and electrolyte imbalances in DI. Severe dehydration can lead to changes in electrolyte levels, which can affect brain function, causing neurologic symptoms like ataxia. This is the most relevant neurologic effect to monitor.
