Which clinical laboratory finding is expected with diabetes insipidus?

Normal serum glucose level

Low serum sodium level

Normal serum sodium level

Elevated serum glucose level

Answer and Explanation

The Correct Answer is C

Diabetes insipidus is a disorder that causes the kidneys to produce large amounts of dilute urine, resulting in dehydration and thirst. Diabetes insipidus is not related to diabetes mellitus, which affects blood glucose levels. Therefore, diabetes insipidus does not affect serum glucose levels, which are expected to be normal.

However, diabetes insipidus can affect serum sodium levels, which are a measure of the concentration of salt in the blood. Due to the loss of water from the body, serum sodium levels can become high (hypernatremia) in diabetes insipidus. However, if the patient drinks enough fluids to compensate for the urine output, serum sodium levels can remain normal.
