Verified
Nephrology Nursing Certification Commission (NNCC) | Computer-Based Testing
Abstract
This document provides a comprehensive set of practice questions with verified
correct answers and rationales designed for hemodialysis technicians preparing for the
Certified Clinical Hemodialysis Technician (CCHT) certification examination
administered by the Nephrology Nursing Certification Commission (NNCC). The
questions are aligned with the 2026 CCHT examination blueprint and encompass all five
content domains: Patient Care and Dialysis Procedures, Infection Control and Safety,
Patient Assessment and Monitoring, Professional Responsibilities and Patient Education,
and Equipment and Technology Troubleshooting. Each question includes a detailed
rationale integrating hemodialysis principles, evidence-based clinical protocols, water
treatment standards, and patient safety guidelines to support comprehensive examination
preparation.
Keywords: CCHT, NNCC, Hemodialysis, Dialysis Technician, Certification Exam,
Vascular Access, Water Treatment, Infection Control, Dialysis Adequacy
1. NNCC CCHT Examination Blueprint Overview
The CCHT certification examination consists of 150 multiple-choice questions
administered via computer-based testing over a 2.5-hour period. The examination assesses
the knowledge and competencies required of clinical hemodialysis technicians who
provide direct patient care under the supervision of registered nurses and nephrologists.
The content is distributed across five primary domains reflecting the scope of
contemporary hemodialysis practice.

water treatment, dialysate
preparation
II: Infection Control & Safety 20–25% Bloodborne pathogens,
disinfection protocols, access
infection prevention
III: Patient Assessment & 15–20% Pre/intra/post-dialysis
Monitoring assessment, vital signs,
complication recognition
IV: Professional 10–15% Documentation, patient
Responsibilities education, dialysis adequacy,
quality improvement
V: Equipment Troubleshooting Integrated with Domain I Alarms, emergencies, machine
maintenance, calibration
Total 150 Questions 2.5 hours, computer-based
testing at Prometric centers
2. Domain I: Patient Care — Dialysis Procedures
1. Which dialysis principle best describes the movement of solutes from an area of higher
concentration to an area of lower concentration across a semi-permeable membrane?
A. Convection B. Ultrafiltration
C. Diffusion D. Osmosis
Correct Answer: C. Diffusion
Rationale: Diffusion is the primary mechanism by which solutes such as urea, creatinine, and
potassium are removed during hemodialysis. Solutes move across the semi-permeable dialyzer
membrane from the blood compartment (higher concentration) to the dialysate compartment
(lower concentration) down their concentration gradient. Convection involves solvent drag
carrying solutes during ultrafiltration. Ultrafiltration is the removal of fluid across the membrane
driven by a hydrostatic pressure gradient. Osmosis refers to the movement of water across a
membrane from low to high solute concentration.
