CCHT Practice Test: Prepare for the BONENT Certification Exam

A CCHT practice test is one of the most effective ways to prepare for the Certified Clinical Hemodialysis Technician exam administered by BONENT (Board of Nephrology Examiners Nursing and Technology). 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 $250 and requires a passing score of 70%. Candidates who use targeted practice questions consistently score higher because they become familiar with the way BONENT 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 BONENT after a candidate meets eligibility requirements that include a high school diploma, completion of a dialysis technician training program, and a minimum of 12 months of clinical experience with at least 1,000 hours of direct patient care in a hemodialysis setting. 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 CCHT exam is divided into five content domains, each weighted differently in scoring. Patient care and machine technology makes up the largest portion at roughly 40% of the exam, testing knowledge of blood pump speed settings, arterial and venous pressure alarm troubleshooting, and proper cannulation techniques for AV fistulas and grafts. Water treatment and dialysate preparation accounts for about 15% and covers 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.

Many dialysis providers, such as DaVita and Fresenius, offer paid CCHT training and will cover your exam fees in exchange for a work commitment.
