A practical nurse (PN) is assigned to collect a sterile urine specimen for culture and sensitivity from a client with a continuous indwelling urinary catheter. In what order should the PN perform the following actions to ensure specimen integrity and minimize the risk of infection? Arrange the steps in the correct chronological sequence.
- 1Clamp the drainage tubing just below the collection port for 15 to 30 minutes.
- 2Scrub the aspiration port with an antimicrobial swab.
- 3Attach a sterile syringe to the port and aspirate the required volume of urine.
- 4Transfer the aspirated urine carefully into a sterile specimen cup.
- 5Remove the clamp from the urinary drainage tubing.
Cevap
The correct sequence begins with clamping the tubing to collect fresh urine, followed by cleansing the port, aspirating the sample with a sterile syringe, transferring it to a sterile container, and finally unclamping the tubing to restore urinary flow.
Obtaining a sterile urine specimen from a closed drainage system requires a strict aseptic sequence to prevent catheter-associated urinary tract infections (CAUTIs) and ensure accurate laboratory results. The nurse must first clamp the tubing to allow fresh, uncontaminated urine to collect. Next, the port must be disinfected to prevent the introduction of pathogens. A sterile syringe is then used to safely aspirate the urine from the port. The sample is transferred to a sterile cup, and finally, the nurse must unclamp the tubing to prevent urinary retention and potential complications.
