In evaluating a 10-year-old child with meningitis suspected of having diabetes insipidus, which finding is indicative of diabetes insipidus?

  • A. Decreased urine specific gravity.
  • B. Elevated urine glucose.
  • C. Decreased serum potassium.
  • D. Increased serum sodium.
Correct Answer: A

Rationale: The correct answer is A: Decreased urine specific gravity. In diabetes insipidus, there is an inability to concentrate urine, leading to decreased urine specific gravity. This is due to the decreased production or action of antidiuretic hormone (ADH). As a result, the kidneys are unable to reabsorb water efficiently, causing dilute urine with low specific gravity.

Incorrect choices:
B: Elevated urine glucose is more indicative of diabetes mellitus, not diabetes insipidus.
C: Decreased serum potassium is not a typical finding in diabetes insipidus.
D: Increased serum sodium can occur due to dehydration from excessive urination in diabetes insipidus, but it is not directly indicative of the condition.
