These domains of the Certified Hemodialysis Technologist exam represent the most essential areas of practice.

In the machine technology domain, on the other hand, you should look for questions related to maintenance of systems, machine set-up, and machine operation/evaluation. In order to succeed on the Certified Hemodialysis Technologist exam, you need to be familiar with the latest equipment.

Within the water treatment domain, meanwhile, are questions about components and the design of systems, the maintenance of systems, and the protocols for monitoring and evaluating systems. In the infection control domain, on the other hand, there are questions about procedures, especially with respect to maintaining a clean and safe patient environment.

The Certified Hemodialysis Technologist examination is not limited to technical subjects, however. In the education and professional development domain, there are questions related to patient education, personal and professional development, and quality-related issues.

All of these subjects are fair game on the exam, so it is essential to study carefully in the coming weeks and months. The Certified Hemodialysis Technologist exam was developed by the Board of Nephrology Examiners and Nursing Technology.
