A nurse is providing instructions about a 24-hr urine collection to an adolescent client. Which of the following should the nurse include in the teaching?

A. Cleansing the perineum with povidone-iodine is not necessary for a routine urine collection. It might be required for specific procedures but not for a 24-hour collection. B. The final specimen should be included in the 24-hour urine collection, not saved separately. C. The first voided specimen should be discarded at the start of a 24-hour urine collection to ensure that the urine collection represents the entire 24-hour period. D. Voiding every hour is not required. The key is to collect urine over the entire 24-hour period.
