A nurse is planning care for a client who has a new diagnosis of diabetes insipidus. Which of the following interventions should the nurse include in the plan of care?

Choice A reason: Diabetes insipidus is unrelated to blood glucose levels. It is caused by a deficiency of antidiuretic hormone (ADH) or renal insensitivity to ADH, leading to excessive urine output and dehydration. Monitoring glucose is not relevant to this condition. Choice B reason: Administering a diuretic would worsen fluid loss in diabetes insipidus. The condition already involves polyuria, and diuretics are contraindicated unless specifically ordered for comorbid conditions. Choice C reason: Checking urine specific gravity is essential in diabetes insipidus. The urine is typically very dilute, with a low specific gravity (<1.005). Monitoring this parameter helps assess the severity of fluid loss and the effectiveness of treatment. Choice D reason: Fluid restriction is contraindicated in diabetes insipidus because the client is already losing excessive fluids. Restricting intake can lead to severe dehydration and electrolyte imbalance. Instead, fluid replacement and hormone therapy are prioritized.
