The Machine & Water Treatment — Dialysis Technician Practice Test
Free CCHT dialysis technician exam practice in English, Chinese, and Spanish — renal physiology and dialysis principles, the machine and water treatment, vascular access, intradialytic complications, and infection control.
22 free practice questions
Practice questions based on the NNCC CCHT content outline, CDC recommendations for hemodialysis settings, and the OSHA Bloodborne Pathogens Standard. Not affiliated with or endorsed by NNCC, and not medical advice. Machine settings, dialysate composition, flow rates, alarm thresholds, water-quality limits and laboratory targets are deliberately never the answer to a question here — those are set by your machine's manufacturer, your facility's protocol and the physician's prescription. Always follow your facility's policies and your patient's prescribed treatment. About the CCHT exam (NNCC) →
