A practical nurse is preparing to collect a urine specimen for culture and sensitivity from a client who has an indwelling urinary catheter. Arrange the following steps for this procedure in the correct chronological sequence.
- 1Clamp the drainage tubing below the level of the specimen collection port.
- 2Scrub the needleless collection port with an antiseptic wipe.
- 3Attach a sterile syringe to the port and aspirate the accumulated urine.
- 4Transfer the aspirated urine from the syringe into a sterile specimen container.
- 5Unclamp the catheter drainage tubing to restore the normal flow of urine.
Answer
The correct sequence is to first clamp the drainage tubing, then scrub the collection port, aspirate the urine with a sterile syringe, transfer it to a sterile container, and finally unclamp the drainage tubing.
The proper procedure for collecting a sterile urine specimen from a closed urinary drainage system minimizes the risk of introducing pathogens and ensures accurate laboratory results. Clamping the tube allows fresh urine to collect. Scrubbing the port maintains sterility. Aspirating and transferring the specimen completes the sterile collection, and unclamping the tube ensures client safety by restoring normal urinary drainage.
