An adult client is prescribed a 24-hour urine collection to evaluate kidney function and creatinine clearance. In which order should the nurse implement the steps of this procedure? Arrange the actions from first to last.
- 1Direct the client to empty their bladder and discard this initial urine.
- 2Document the exact time of the discarded void as the start of the collection period.
- 3Save all subsequent urine output in a designated container kept on ice or refrigerated.
- 4Instruct the client to void exactly 24 hours after the start time and add this to the collection.
Answer
The correct sequence begins with having the client void and discarding that urine, noting the exact time as the start, collecting all subsequent urine in a cooled container, and ending with one final void added exactly 24 hours later.
A 24-hour urine collection requires precise timing and strict collection protocols to yield accurate diagnostic results. The procedure mandates starting with an empty bladder (discarding the first void) to ensure only urine produced during the 24-hour timeframe is measured. The exact time of this first void marks the official start. From then on, every drop of urine must be collected and kept cool to preserve its chemical integrity. Finally, exactly 24 hours after the start time, the client must void one last time to complete the physiological sample window.
