A patient with polyuria shows a high specific gravity in the urine.The patient should be evaluated for:
A) Renal tubular acidosis
B) Diabetes mellitus
C) Diabetes insipidus
D) Prostatic infection

Question

Quizplus · Accepted Answer

A high specific gravity in urine indicates a concentrated urine. In the context of polyuria (excessive urination), this finding is more consistent with diabetes mellitus, where high blood sugar levels lead to glucose in the urine, which increases the urine's specific gravity. Diabetes insipidus, in contrast, typically presents with a low specific gravity due to the production of large volumes of dilute urine. Renal tubular acidosis and prostatic infection are not directly associated with changes in urine specific gravity in the context described.
