How much urine is typically produced in a day by a healthy adult?

  1. 500 mL

  2. 1000 mL

  3. 1500 mL

  4. 2000 mL

The correct answer is: 1500 mL

A healthy adult typically produces around 1500 mL of urine per day. Option A (500 mL) is too low, as this would only indicate a small amount of fluid consumption and would not be enough to adequately flush waste from the body. Option B (1000 mL) is closer, but still may not be enough for an adequately hydrated adult. Option D (2000 mL) is too high, as this would indicate excessive fluid intake or a potential medical issue such as diabetes or kidney disease. Therefore, option C is the most accurate and reasonable estimation for the amount of urine produced in a day by a healthy adult.
