For the treatment of diabetes insipidus, which options are appropriate? Select three.

Vasopressin, also known as antidiuretic hormone (ADH), is the primary treatment for diabetes insipidus, especially in cases where the condition is due to a deficiency of this hormone, often termed central diabetes insipidus. This medication works by increasing water reabsorption in the kidneys, thus reducing the volume of urine produced and helping to concentrate it. This is crucial for patients with diabetes insipidus, who typically experience excessive urination and problem with fluid balance.

The suggestion to ask the patient to drink more water is generally part of managing symptoms but does not address the underlying condition, particularly in central diabetes insipidus where the hormone responsible for water regulation is lacking. While staying hydrated is important, it alone cannot replace the need for hormone replacement therapy.

Administering IV hypertonic saline is not an appropriate treatment for diabetes insipidus and might instead be used in different contexts, such as treating hyponatremia. Similarly, restricting salt intake does not specifically address the deficit of vasopressin nor does it treat the condition effectively. Instead, the management focuses on the appropriate administration of vasopressin or desmopressin, which mimics its action.

Thus, vasopress
