2. disconnect the catheter from the drainage tubing and allows 1–3 mL of urine to drain into a sterile specimen container
3. with a sterile syringe and needle, aspirate 50 mL of urine from the catheter above where it is connected to the drainage tubing
4. empty a small volume of urine from the urine collection bag into a sterile specimen cup
Correct Answer: 1
Several mL of urine can be aspirated with a sterile syringe from the sampling port using sterile technique. The urinary catheter and drainage system should remain a closed system to prevent infection. Urine in the drainage bag has collected over several hours and is not fresh, as needed for a culture specimen.
