CCHT Clinical Practice Test

Last Updated on June 14, 2025

The Nephrology Nursing Certification Commission (NNCC) Certified Clinical Hemodialysis Technician (CCHT) Clinical Practice Test 2025 – Questions and Answers Quiz. In the actual test, this part consists of 71 to 78 multiple-choice questions, which is approximately 48–52%.

Questions in the Clinical area deal with patient care before, during, and after dialysis treatment. Sometimes, a patient case is described, and several questions follow, as seen in the case of Ivan Jackson in the Prep Test at the end of this booklet. Other questions are individual items that stand alone. The Clinical area is the most significant part of the test, making up 50% of the test content. Examples of the kinds of technician activities tested in the Clinical area include:

1. Using aseptic technique for dialysis procedures.
2. Evaluating the patient’s access before dialysis.
3. Cannulating the patient’s access.
4. Monitoring patient during dialysis treatment, e.g., vital signs.
5. Discontinuing the patient’s dialysis treatment with an arteriovenous fistula or graft.
