Dialysis Technician Practice Exam

What is the initial step in the port/catheter pre-dialysis assessment?

1. Assessing the blood flow rate

2. Assessing the ease of heparin removal and saline flushing

3. Checking for signs of infection

4. Verifying the patient’s dialysis prescription

The correct answer is: Assessing the ease of heparin removal and saline flushing

The initial step in the port or catheter pre-dialysis assessment focuses on assessing the ease of heparin removal and saline flushing. This is crucial as it directly relates to the functionality of the access point for dialysis. Ensuring that the heparin can be effectively removed and that saline can be flushed through the catheter indicates that the flow is unobstructed and the access is patent, which is vital for the effectiveness and safety of the dialysis process. If there are complications in flushing or removing heparin—such as a clot being present—dialysis cannot proceed safely or effectively. Thus, this assessment lays the groundwork for any further actions needed to prepare the patient for the treatment. By ensuring that the catheter is functioning correctly right from the start, healthcare professionals can avoid delays or complications during the dialysis session. The other steps, such as checking for signs of infection or verifying the dialysis prescription, are also important and should be performed but are secondary to confirming the immediate functionality of the catheter. This ensures that the patient can receive their treatment as planned without interruption.
