Which laboratory finding is indicative of diabetes insipidus (DI)?
Low blood glucose levels.
Elevated urine osmolality.
Hypernatremia.
High urine glucose levels.
The Correct Answer is B
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.

Correct Answer is B
Explanation
The kidneys are the main target organ affected by the hyposecretion of antidiuretic hormone (ADH) in diabetes insipidus. ADH normally acts on the kidneys to promote water reabsorption and concentrate urine. In diabetes insipidus, the lack of ADH results in excessive urine production and dilute urine.
Incorrect choices:
a. This choice is incorrect. The liver is not the primary target organ affected by ADH in diabetes insipidus.
c. This choice is incorrect. The pancreas is not the primary target organ affected by ADH in diabetes insipidus.
d. This choice is incorrect. The heart is not the primary target organ affected by ADH in diabetes insipidus.
Correct Answer is C
Explanation
Clients with diabetes insipidus may experience electrolyte imbalances, including hypernatremia and hyperkalemia. Monitoring serum potassium levels is important to prevent complications.
Incorrect choices:
a. This choice is incorrect. Administering diuretics is not appropriate for a client with diabetes insipidus, as they are already experiencing excessive fluid loss.
b. This choice is incorrect. While encouraging fluid intake is important, excessive fluid intake may exacerbate fluid loss in clients with diabetes insipidus.
d. This choice is incorrect. Antidiabetic medications are used to manage diabetes mellitus, not diabetes insipidus.
