A practical nurse is initiating a 24-hour urine collection to evaluate a client's renal function. To ensure the accuracy of the diagnostic test and prevent measurement errors, arrange the following nursing actions in the correct chronological sequence.
- 1Instruct the client to empty their bladder completely and discard this initial urine specimen.
- 2Record the precise time of the discarded void to establish the official start time of the test.
- 3Transfer all subsequent urine output into the designated collection container kept on ice.
- 4Instruct the client to void one final time exactly 24 hours after the established start time.
- 5Add the final urine specimen to the cooled container and transport the entire collection to the laboratory.
Cevap
The correct sequence is to first have the client void and discard the urine, then document this exact time as the start time, collect all subsequent urine on ice for the next 24 hours, instruct the client to void exactly 24 hours later, and finally add this last specimen to the container before sending it to the laboratory.
A 24-hour urine collection requires precise timing to accurately measure renal function or hormone levels. The client must begin the test with an empty bladder, meaning the very first void is always discarded. The time of this discarded void becomes the official start time. All subsequent urine must be collected and properly stored (usually on ice or refrigerated) to prevent chemical degradation of the specimen. Exactly 24 hours after the start time, the client must void one final time to complete the collection. This final void is added to the container, which is then immediately dispatched to the laboratory.
