Question

Quizplus · Accepted Answer

Polyuria is an excessive production of urine, which can be caused by diabetes mellitus (DM) due to the presence of glucose in urine (glucosuria). The high glucose levels in the urine alter the osmotic effect in the kidney, resulting in the retention of water in the urine, increasing its volume. Therefore, option A and C are correct. Additionally, the increased glucose in the urine leads to increased sodium excretion, resulting in less Na+ in the urine, thus making option B incorrect.
