Normal Urine Volume in 24-Hour Collection

A nurse is preparing a patient for a kidney function test that requires a 24-hour urine collection to measure levels of various substances. It is crucial for the patient to understand the process involved in collecting and conserving urine over a full day to ensure accurate test results. The nurse explains that the patient's urine output needs to be completely collected and refrigerated. Additionally, the nurse instructs the patient to discard the first urination in the morning on the day of the collection. The nurse reinforces that the collection will begin after this first urination and will continue for the next 24 hours. During this period, the patient is informed to limit fluid intake to avoid dilution of urine samples. To calculate the total volume of urine collected over the 24 hours, the patient is encouraged to measure and add up the volume every time they urinate. The expected normal range for total urine volume collected in a 24-hour period typically varies, but is generally expected to be between ___________ mL.
