Dialysis Technician Practice Exam

What are the two hemodialysis delivery systems?

1. Dialysate and Filtrate

2. Extracorporeal and Dialysate

3. Continuous and Intermittent

4. Home and In-Center

The correct answer is: Extracorporeal and Dialysate

The correct identification of the two hemodialysis delivery systems is rooted in understanding how hemodialysis treatment is administered. Hemodialysis primarily involves two main systems: "extracorporeal" and "dialysate." Extracorporeal refers to the process of blood being removed from the body, filtered through a dialyzer (also known as an artificial kidney), and then returned to the body. This system is crucial because it encompasses the physical movement of blood outside the body during treatment. Dialysate, on the other hand, is the fluid used in the dialysis process to draw waste products and excess minerals and fluids from the blood. The correct balance of dialysate maintains the necessary osmotic gradient to facilitate the diffusion of waste from the blood into the dialysate, effectively cleaning the blood. The combination of these two systems — the extraneous movement of blood and the use of a specially formulated dialysis solution — is essential for effective hemodialysis treatment. Understanding this interaction is fundamental for those working in the field as it contributes directly to patient care and treatment efficiency.
