- How are you now?
- Are you comfortable?
- I understand that you are having a urinary catheter and am here to take your urine sample from your catheter for culture
- Is that ok with you?
- Do we need a chaperone for this? (Normally examiner tells no need for that)
- Do you have any allergies?
- Are you in any pain?
- Do you need to use the toilet now, as our procedure will take another 15 minutes, is that ok for you?

Clamping the Catheter
- I am going to put an apron and gloves
- Confirming with the examiner that trolley is clean with soap and water in past 24 hours
- I am taking the clamp with me and clamping the urinary catheter few cms distal to the sampling port (Verbalize to patient that in case of any discomfort or fullness of bladder, call you so that you can unclamp the catheter – In usual scenario, catheter will be clamped and consent will be taken and given in the scenario)
- I am removing the apron and gloves, discarding it into clinical waste
- If using needle and syringe:
– inserts needle into port at an angle of 45°, using a non-touch technique, and aspirates the required amount of urine, then withdraws needle.
– If using needless system: inserts sterile syringe firmly into centre of sampling port (according to manufacturer’s guidelines) using a non-touch technique, aspirates the required amount of urine, and removes syringe.

- Am wiping the port for 30 seconds and allowing it to dry for another 30 seconds
- Opening the 20 ml syringe and withdrawing the urine, showing to examiner that 10 ml of urine (as given in scenario) is withdrawn and urine is clear in normal color

- Removing the incopad and putting it in clinical waste
- Un clamping the catheter

Post Procedural Phase
- Verbalizing to the patient that procedure is over, are you comfortable now?
- Telling to the patient that i will be sending the sample to the laboratory now, if not possible i will be refrigerating it at 4 degree Celsius and will try to send it within 4 hours
- Give the call bell to the patient and asks him to press the call bell if he or she needs any assistance
- Am taking back my trolley, discarding waste, cleaning it and making it ready for next use
- Filling the culture form, documenting the procedure along with the color and nature of urine observed
- Opening the curtains back

Pitfalls – Candidate can fail if Candidate takes the sample from the incorrect port, either leg bag emptying port OR water balloon port.
Key points are you should state the condition of urine after pouring it to the container, you should unclamp the catheter / discard needle in the sharps bin and you should wipe sampling port twice. Normally, urine sample will be needed to place on the shelf, no need to document as it will be pre documented as per scenario.
