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.

Correct Answer is C
Explanation
Remove gloves, wash hands, remove face shield, gown, mask, and wash hands again. This is because gloves are the most contaminated piece of PPE and should be removed first to avoid touching other parts of the body or environment with them. Washing hands after removing gloves is also important to reduce the risk of infection. Face shields, gowns, and masks should be removed in that order, as they are less contaminated than gloves and can be handled with clean hands. Washing hands again after removing all PPE is the final step to ensure hygiene.
Choice A is wrong because it does not include washing hands after removing gloves, which is a crucial step to prevent contamination. It also removes the gown before the gloves, which can cause the gown to touch the face or hair and contaminate them.
Choice B is wrong because it does not include washing hands between removing gloves and gown, which can transfer germs from the gloves to the gown and then to the face or hair when removing the face shield and mask.
Choice D is wrong because it does not include washing hands between removing gloves and gown, which can transfer germs from the gloves to the gown and then to the face or hair when removing the face shield and mask. It also removes the gown before the face shield, which can cause the gown to touch the face or hair and contaminate it.
Normal ranges for PPE removal are not applicable as different types of PPE may require different methods of removal. However, some general principles are to remove PPE in a way that minimizes contact with contaminated surfaces, perform hand hygiene frequently, and dispose of PPE properly.
Correct Answer is B
