Which is the most appropriate action when obtaining a sterile urine specimen from an indwelling urinary catheter?
Swab the collection port of the catheter with an antiseptic swab. Insert a sterile needle and aspirate 3 to 5 mL of urine into the syringe.
Immediately clamp the catheter tubing.
Return one hour later and empty 3 to 5 mL of urine from the drainage bag into a sterile specimen container.
Flush the catheter with 10 mL of sterile water.
The Correct Answer is A
Insert a sterile needle and aspirate 3 to 5 mL of urine into the syringe. This is the best technique for obtaining a sterile urine specimen from an indwelling urinary catheter because it ensures that microorganisms in the specimen are from the urine, and not the result of contamination.
Choice B is wrong because it does not use sterile technique and it does not collect fresh urine. The urine in the drainage bag may have been sitting there for a long time and may not reflect the current condition of the patient’s urinary tract.
Choice C is wrong because it does not use sterile technique and it flushes the catheter with sterile water, which may dilute the urine and alter its composition.
Choice D is wrong because it does not use sterile technique and it collects urine from the drainage bag, which may be contaminated or stale.
