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 B
Explanation
“My medication will be given at the scheduled times to best manage my pain.” This statement demonstrates understanding of the pain management plan because it shows that the client knows the importance of preventing pain from becoming severe by taking medication regularly. Scheduled administration of analgesics is more effective than administering them on demand.
Choice A is wrong because it implies that the client will wait until the pain is severe before asking for medication, which can make it harder to control.
Choice C is wrong because it suggests that the client expects to receive inadequate pain relief due to their history of opioid abuse, which is not ethical or evidence-based.
Choice D is wrong because it indicates that the client believes they will be denied any narcotics for pain, which is also not ethical or
evidence-based. Clients with a history of opioid abuse can still receive opioids for acute pain, but they may need higher doses or more frequent administration to achieve adequate analgesia.
Normal ranges for vital signs are as follows: respiratory rate 12-20 breaths per minute, heart rate 60-100 beats per minute, blood pressure 120/80 mmHg, temperature 36.5-37.5°C (97.7- 99.5°F).
