Elevated urine specific gravity.
Hypernatremia.

Hypouricemia.
The Correct Answer is B
Hypernatremia, or elevated sodium levels, is a common laboratory finding in clients with diabetes insipidus due to the excessive loss of water in urine.
Incorrect choices:
a. This choice is incorrect. Elevated urine specific gravity is not typically seen in diabetes insipidus; instead, urine specific gravity is often diluted.
c. This choice is incorrect. Low serum osmolality is not characteristic of diabetes insipidus, which is associated with concentrated serum.
d. This choice is incorrect. Hypouricemia refers to low levels of uric acid and is not directly related to diabetes insipidus.
