Which diagnostic test measures the concentration of antidiuretic hormone (ADH) in the blood and is used to differentiate between central and nephrogenic diabetes insipidus?

Clients with diabetes insipidus should maintain a balanced and adequate diet to ensure proper nutrition and hydration. While fluid intake may need to be monitored, severe fluid restriction is not typically necessary.

Incorrect choices:

a. This choice is incorrect. Avoiding all sources of dietary sodium is not a standard dietary recommendation for diabetes insipidus. Sodium balance is important for overall health.

b. This choice is incorrect. There is no specific indication for a high-protein diet in the management of diabetes insipidus.

c. This choice is incorrect. Limiting fluid intake to 1 liter per day may not be appropriate for all clients and should be based on individual needs and medical guidance.

The desmopressin stimulation test measures the response of the kidneys to synthetic ADH (desmopressin) and is used to differentiate between central and nephrogenic diabetes insipidus.

Incorrect choices:

a. This choice is incorrect. The glucose tolerance test is used to diagnose diabetes mellitus, not diabetes insipidus.

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.
