Certified Dialysis Nurse Practice Test

Question: 1 / 400

What is the recommended blood flow rate for hemodialysis?

100 to 200 mL/min

200 to 300 mL/min

300 to 500 mL/min

The recommended blood flow rate for hemodialysis typically falls between 300 to 500 mL/min. This range is considered optimal to ensure effective clearance of waste products from the blood and to maintain hemodynamic stability during the treatment process. A blood flow rate within this range allows for adequate dialysate contact time, which enhances the efficiency of solute removal while minimizing complications.

When operating at this rate, the dialysis machine can effectively manage the patient's hemodynamics, ensuring that there is sufficient blood flow to facilitate adequate ultrafiltration and dialysis functions. Higher or lower rates may not provide the necessary balance of efficiency and safety required during treatment. Therefore, the choice of a blood flow rate between 300 to 500 mL/min is crucial for effective hemodialysis therapy.
