Dialysis Technician Practice Exam

What is the primary purpose of a proportioning system in dialysis?

1. To provide nutritional support

2. To make dialysate by mixing fresh concentrate with fixed amounts of treated water

3. To measure blood pressure accurately

4. To monitor patient's vitals during the procedure

The correct answer is: To make dialysate by mixing fresh concentrate with fixed amounts of treated water

The primary purpose of a proportioning system in dialysis is to make dialysate by mixing fresh concentrate with fixed amounts of treated water. This system is crucial because dialysate is an essential component in the dialysis process, as it helps to draw waste products out of the blood and maintain the desired chemical balance in the patient’s body. A proportioning system ensures that the dialysate is prepared with the correct concentrations of electrolytes and other substances, which is necessary for effective dialysis treatment. By accurately mixing the concentrate and water, the system helps meet the specific needs of the patient and ensures that the dialysis process is efficient and safe. Other options, such as providing nutritional support or measuring blood pressure, do not directly relate to the formulation of dialysate, which is the cornerstone of the dialysis procedure. Monitoring patient vitals is important during dialysis but is not the function of the proportioning system itself. Thus, the focus of a proportioning system is undoubtedly on the preparation of dialysate, making its role vital in the overall success of dialysis treatment.
