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

Choice A reason: Moist mucous membranes are not expected in diabetes insipidus (DI), which causes excessive water loss due to deficient antidiuretic hormone, leading to dehydration and dry mucous membranes. This finding is more typical in conditions with fluid retention, like SIADH, making it incorrect. Choice B reason: Urine specific gravity of 1.000 (dilute urine) is expected in DI, as deficient antidiuretic hormone reduces renal water reabsorption, causing large volumes of dilute urine. This reflects the kidneys’ inability to concentrate urine, a hallmark of DI, making it the correct finding. Choice C reason: Bradycardia is not typical in DI. Dehydration from excessive water loss increases heart rate (tachycardia) as a compensatory response to maintain cardiac output. Bradycardia may occur in other conditions but not in DI’s hypervolemic state, making this choice incorrect. Choice D reason: Bounding peripheral pulses are not expected in DI, where dehydration reduces blood volume, leading to weaker pulses. Bounding pulses occur in hyperdynamic states like thyrotoxicosis, not DI’s hypovolemic state, making this an incorrect finding for the condition.
