The desmopressin stimulation test involves administering synthetic ADH (desmopressin) to assess the response of the kidneys and 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.
Correct Answer is B
Explanation
In diabetes insipidus, the inability to concentrate urine leads to diluted urine with low osmolality. An elevated urine osmolality is indicative of the inability to properly conserve water.
Incorrect choices:
a. This choice is incorrect. Low blood glucose levels are not characteristic of diabetes insipidus.
c. This choice is incorrect. Hypernatremia, or elevated sodium levels, can result from excessive fluid loss in diabetes insipidus, but it is not a direct diagnostic indicator.
d. This choice is incorrect. High urine glucose levels are indicative of diabetes mellitus, not diabetes insipidus.
