A nurse is instructing a client on the proper procedure for a 24-hour urine collection for creatinine clearance. In what chronological order should the nurse instruct the client to perform the following steps? Arrange the steps in the correct sequence.
- 1Empty the bladder completely into the toilet and discard this initial urine.
- 2Document the exact time of the discarded void as the official start time.
- 3Collect all subsequent urine voids in the designated refrigerated specimen container.
- 4Void one final time exactly 24 hours after the start time and add it to the container.
- 5Transport the completed collection container to the laboratory.
Cevap
The correct sequence is to first discard the initial void, document the start time, collect all subsequent urine for 24 hours, void one final time at the 24-hour mark, and finally transport the specimen to the laboratory.
For a 24-hour urine collection, the bladder must first be emptied and that urine discarded so the collection period begins with an empty bladder. The exact time is then recorded as the start time. All subsequent urine voided over the next 24 hours is saved in a designated container, which is typically kept on ice or refrigerated. Exactly 24 hours after the start time, the client voids one last time and adds it to the container to complete the collection. Finally, the complete specimen is transported to the laboratory.
