Zorluk: OrtaReduction of Risk Potential

A practical nurse is preparing to collect a sterile urine specimen for a culture and sensitivity test from a client who has an indwelling urinary catheter. Arrange the following procedural steps in the correct chronological order.

  1. 1Clamp the catheter drainage tubing just below the level of the specimen collection port.
  2. 2Scrub the needleless specimen collection port briskly with an antimicrobial swab.
  3. 3Attach a sterile syringe to the needleless port and withdraw the required volume of urine.
  4. 4Carefully transfer the aspirated urine into a sterile specimen container.
  5. 5Unclamp the catheter drainage tubing and verify the unobstructed flow of urine.

Cevap

The correct sequence is: clamp the tubing, scrub the port, withdraw the urine, transfer to the container, and unclamp the tubing.
Obtaining a sterile urine specimen from an indwelling catheter requires maintaining the closed drainage system to prevent infection and ensuring a fresh sample. First, the tubing is clamped to collect fresh urine. Next, the port is disinfected to prevent introducing microorganisms. Then, the sterile syringe is used to withdraw the sample, which is subsequently transferred to a sterile cup. Finally, the tubing must be unclamped immediately to restore continuous urinary flow and prevent bladder distension.

Adım Adım Çözüm

1
Clamp the catheter drainage tubing just below the specimen collection port.
Fresh urine accumulates in the tubing.
Urine collected from the drainage bag is not sterile and cannot be used for a culture. Clamping ensures a fresh sample is available.
2
Scrub the needleless specimen collection port briskly with an antimicrobial swab.
The surface of the port is disinfected.
This prevents bacteria on the surface from entering the closed catheter system or contaminating the urine sample.
3
Attach a sterile syringe to the needleless port and withdraw the required volume of urine.
Urine is safely extracted from the tubing.
Using a needleless sterile syringe maintains the sterility of the closed drainage system while retrieving the sample.
4
Carefully transfer the aspirated urine into a sterile specimen container.
The sample is secured in a sterile environment.
Transferring the sample without touching the inside of the container keeps the urine uncontaminated for accurate laboratory analysis.
5
Unclamp the catheter drainage tubing and verify the unobstructed flow of urine.
Normal, continuous urine flow is restored.
Forgetting to unclamp the tubing can lead to urinary stasis, severe bladder distension, and an increased risk of infection.
