CCHT Practice Test: Prepare for the NNCC Certification Exam
A CCHT practice test is one of the most effective ways to prepare for the Certified Clinical Hemodialysis Technician exam administered by the Nephrology Nursing Certification Commission (NNCC), with the Center for Nursing Education and Testing (C-NET) handling applications and PSI delivering the computer-based test. The actual CCHT exam contains 150 multiple-choice questions covering water treatment and dialysate preparation, principles of dialysis, dialyzer reprocessing, patient care and machine technology, and safety. Practice tests that mirror this format help candidates identify weak areas in their knowledge before sitting for the real exam, which costs $225 and requires a standard score of 95, reached by answering about 74% of the questions correctly. Candidates who use targeted practice questions consistently score higher because they become familiar with the way NNCC frames clinical scenarios around vascular access monitoring, fluid removal calculations, and infection control protocols specific to the hemodialysis setting.
What Is a CCHT and Why Does This Credential Matter?
A CCHT is a healthcare professional who operates hemodialysis machines, monitors patients during treatment sessions, and maintains the equipment and water systems used in dialysis clinics. The CCHT credential is awarded by NNCC after a candidate meets eligibility requirements that include a high school diploma or GED, completion of a hemodialysis technician training program with both classroom instruction and RN-supervised clinical experience, and compliance with CMS and state regulations; NNCC recommends, but does not require, at least six months (about 1,000 hours) of clinical experience before testing. Holding the CCHT designation signals to employers like DaVita, Fresenius Kidney Care, and hospital-based dialysis units that a technician has demonstrated competency in critical areas including calculating ultrafiltration rates, responding to intradialytic complications such as hypotension and muscle cramping, and following CMS infection control guidelines. Many states now require or prefer CCHT certification for dialysis technicians, and certified technicians typically earn $3,000 to $7,000 more annually than their uncertified counterparts.
Key Topics Covered on the CCHT Exam
The official NNCC test blueprint divides the 150-item CCHT exam into four dialysis practice areas: Clinical (48-52%), Technical (21-25%), Environment (13-17%), and Role Responsibilities (10-14%). The Clinical area is the largest and tests blood pump speed settings, arterial and venous pressure alarm troubleshooting, and proper cannulation techniques for AV fistulas and grafts. Water treatment and dialysate preparation fall under the Technical and Environment areas and cover reverse osmosis system monitoring, chloramine testing, and bicarbonate concentrate mixing ratios. The principles of dialysis section tests understanding of diffusion, osmosis, ultrafiltration, and solute clearance — candidates should be comfortable calculating Kt/V values and understanding adequacy targets. Dialyzer reprocessing, though being phased out at some facilities, still appears on the exam and covers germicide testing with MPA strips, total cell volume measurements, and AAMI standards for reuse. Reviewing each domain systematically rather than studying randomly gives candidates the best chance of passing on their first attempt.
CCHT Exam
The CCHT exam is the national certification test for hemodialysis technicians, offered through the Nephrology Nursing Certification Commission (NNCC). The NNCC CCHT exam is a computer-based, multiple-choice test that checks whether you can safely run dialysis treatments. Questions are grouped into clinical care, technical operation of machines and water systems, the dialysis environment, and professional role responsibilities.
Expect scenario questions about patient monitoring during treatment, responding to alarms and complications, infection control, and dialyzer and dialysate handling. The best preparation is to review each area in turn, then test yourself with realistic questions and read every explanation, including the ones you answered correctly. Confirm current eligibility rules, fees and scheduling directly with NNCC before you apply.

Sample CCHT - Certified Clinical Hemodialysis Technician Practice Questions
Try these questions from our free CCHT - Certified Clinical Hemodialysis Technician practice tests. The correct answer and an explanation follow each question.
How should a CCHT respond to a patient who repeatedly refuses to follow their prescribed dietary restrictions and is consistently arriving with high fluid gains?
- A. Report the patient to administration for non-compliance
- B. Provide supportive education, involve a social worker and dietitian, and document all interventions without threatening the patient
- C. Increase ultrafiltration rate to compensate for the extra fluid without discussion
- D. Suggest the patient consider discontinuing dialysis
Answer: B. Provide supportive education, involve a social worker and dietitian, and document all interventions without threatening the patient
Non-compliance requires a compassionate, multidisciplinary approach addressing barriers to adherence rather than punitive measures, while documenting all interventions.
Which aspect of patient care is the CCHT responsible for documenting in the treatment record?
- A. Only final lab results and total fluid removed
- B. All treatment parameters, vital signs, interventions, patient symptoms, and communications with clinical staff
- C. Equipment serial numbers and supply usage only
- D. Physician orders received during treatment only
Answer: B. All treatment parameters, vital signs, interventions, patient symptoms, and communications with clinical staff
The CCHT must document a complete record of all treatment parameters, patient responses, vital signs, interventions performed, and communications to ensure legal accountability and continuity of care.
What is the role of the CCHT in a dialysis patient's care conference?
- A. CCHTs are not included in care conferences
- B. Provide direct care observations: machine tolerance, access performance, vital sign trends, patient behavior/complaints during treatments
- C. Only sign the care plan documents prepared by nurses
- D. Report on supply inventory and equipment maintenance issues
Answer: B. Provide direct care observations: machine tolerance, access performance, vital sign trends, patient behavior/complaints during treatments
CCHTs spend the most time with patients during treatment and can provide unique observations about hemodynamic tolerance, access function, and patient behavior that inform the care plan.
If a patient has refused to participate in education, asks no questions, and shows no interest in learning about hemodialysis, the best approach for the technician is to _____________.
- A. talk through all the steps in the procedures
- B. continue to ask if the patient has questions
- C. tell the patient that learning is important
- D. stop attempts to teach the patient
Answer: A. talk through all the steps in the procedures
Even if a patient shows no overt interest, consistently talking through the steps of the procedure provides passive education. This allows the patient to absorb information at their own pace and may spark questions or understanding over time, without pressuring them to actively participate. It ensures that essential information is still conveyed, fulfilling the technician's role in patient care and safety.
