NHA Phlebotomy Certification Practice Exam

When encountering a patient with a fistula, what should the phlebotomist do?

1. Apply the tourniquet below the fistula

2. Use the other arm

3. Collect the blood from the fistula

4. Attach a syringe to the T-tube connector

The correct answer is: Use the other arm

When a phlebotomist encounters a patient with a fistula, the most appropriate action is to use the other arm for blood collection. A fistula is an artificial connection between an artery and a vein, typically created for dialysis patients. This site is not suitable for venipuncture because it is designed to handle larger volumes of blood flow and pressure, which can be compromised if blood is drawn from it. Additionally, drawing blood from a fistula can lead to complications such as clotting or infection. Using the other arm prevents damage to the fistula and ensures that the patient’s vascular access remains intact for future dialysis sessions. This approach prioritizes patient safety and adherence to best practices in phlebotomy.
