CCHT-A case studies
CCHT-A · Put your knowledge to work in context.
The Certified Clinical Hemodialysis Technician – Advanced (CCHT-A) is a nephrology certification credential offered by the Nephrology Nursing Certification Commission (NNCC). NNCC describes the CCHT-A as reserved for clinical dialysis technicians with at least 5,000 hours and 5 years of experience, which separates it from the entry-level CCHT credential open to practicing dialysis technicians holding a high school diploma or GED. The exam is intended for technicians who already run routine treatments competently and want their advanced judgment in machine and water-system management, patient teaching, and quality work validated. Content spans four practice domains: clinical practice; dialysis delivery systems and water treatment; patient education and support; and professional practice and quality improvement. The CCHT-A case studies are 5 cases and about 3,588 words.
