A nurse is assessing a client who has diabetes insipidus. Which of the following findings should the nurse expect?

A. Dehydration is correct because diabetes insipidus causes large amounts of dilute urine output due to deficient ADH, leading to excessive fluid loss and dehydration. B. Bradycardia is incorrect because dehydration more commonly causes tachycardia, not bradycardia. C. Hyperglycemia is incorrect because this is associated with diabetes mellitus, not diabetes insipidus. D. Polyphagia is incorrect because excessive hunger is a manifestation of diabetes mellitus, not diabetes insipidus.
