b. This choice is incorrect. A serum electrolyte panel provides information about electrolyte levels but is not specific to diabetes insipidus diagnosis.
c. This choice is incorrect. The water deprivation test, not the desmopressin stimulation test, is used to diagnose diabetes insipidus and assess the ability of the kidneys to concentrate urine.
Correct Answer is D

Desmopressin (DDAVP) is a synthetic form of antidiuretic hormone (ADH) that is commonly used to manage diabetes insipidus by increasing water reabsorption in the kidneys and reducing urine output.
Incorrect choices:
a. This choice is incorrect. Limiting fluid intake to 500 mL per day is not a typical management approach for diabetes insipidus. Adequate fluid intake is necessary to prevent dehydration.
