Zorluk: OrtaReduction of Risk Potential

A practical nurse (PN) is assigned to collect a sterile urine specimen for culture and sensitivity from a client who has a continuous indwelling urinary catheter. Arrange the following nursing actions in the correct chronological order to safely collect the specimen and minimize the risk of complications.

  1. 1Clamp the catheter drainage tubing just below the needleless access port for 15 to 30 minutes.
  2. 2Scrub the needleless access port with an antiseptic wipe and allow it to air-dry.
  3. 3Attach a sterile luer-lock syringe to the access port and aspirate the required volume of urine.
  4. 4Transfer the aspirated urine into a sterile specimen container without touching the rim or inside of the cup.
  5. 5Unclamp the catheter drainage tubing to verify that normal urine flow into the collection bag resumes.

Cevap

The correct sequence is to first clamp the tubing to collect fresh urine, then disinfect the port, aspirate the sample with a syringe, transfer it to a sterile container, and finally unclamp the tubing to prevent bladder distension.
Safe and effective collection of a sterile urine specimen requires a logical sequence that prioritizes both infection control and client safety. The tubing is clamped first to gather fresh urine. The port is then sanitized to maintain a sterile barrier. The sample is aspirated and secured in a sterile container. Finally, unclamping the tube immediately after the procedure is a critical risk-reduction step to prevent urinary retention and potential renal injury.

Adım Adım Çözüm

1
Clamp the drainage tubing below the port.
Fresh urine accumulates near the sampling port.
Urine in the drainage bag is stagnant and not suitable for an accurate culture. Clamping ensures fresh urine from the bladder is collected.
2
Disinfect the sampling port with an antiseptic wipe.
The surface of the port is free of microorganisms.
Maintaining the sterile integrity of the closed urinary system is essential to prevent a catheter-associated urinary tract infection (CAUTI).
3
Aspirate urine using a sterile syringe.
The necessary volume of uncontaminated urine is collected.
Using a sterile syringe prevents the introduction of bacteria while safely extracting the sample.
4
Transfer the specimen to a sterile cup.
The sample is safely housed for transport to the laboratory.
The inside of the cup and lid must remain sterile to ensure laboratory results reflect the client's actual flora rather than environmental contaminants.
5
Unclamp the catheter tubing.
Continuous urinary drainage is restored.
Leaving the catheter clamped is a major safety risk that can lead to acute urinary retention, bladder trauma, or kidney damage.
