Product Information

Product Description

Most CCHT prep books will get you to exam day feeling ready. Then the first question appears — a clinical scenario, four plausible answers, and the slow realization that nothing you studied prepared you to apply what you know.This book was built to close that gap.The CCHT is a federal requirement. You have 18 months from your hire date to pass — or you cannot continue working as a hemodialysis technician. This book was written to make sure you pass on the first attempt.What sets this book apart:Water treatment coverage no competitor matches. Water treatment is 21–25% of your exam — 26–31 scored questions. Most prep books give it 2–4 pages. This book gives it three full chapters:• Every component, what it removes, and what happens to patients when it fails• Chloramine breakthrough, carbon EBCT, RO rejection rates, DI resistivity, endotoxin limits• Exact testing protocols and out-of-range action steps the exam testsWater treatment has failed more CCHT candidates than any other domain. Not here.The only CCHT prep book with a dedicated Complication Chart System. Every intradialytic emergency — air embolism, hemolysis, disequilibrium syndrome, first-use reaction, cardiac arrest — presented in the same framework:• Primary causes• Key signs and symptoms• Exact technician action sequence, step by step• Immediate nurse notification: yes or noA condensed master version appears in the back matter for the night before your exam.1,200+ practice questions at real exam difficulty.• 270 chapter review questions across all 11 chapters• 2 complete 150-question full-length practice exams• 1,000+ additional questions via QR code — by domain and difficulty, full rationales included• Every question explains why the right answer is right and why each wrong answer is wrongThe NNCC blueprint states 63–67% of questions are application-level. This book matches that exactly. If the questions feel harder than other prep books you have used, they are. That is the point.Blueprint-aligned. Zero filler. Both practice exams mirror the real exam weighting:• 50% Patient Care• 23% Water Treatment and Machine Technology• 8% Infection Control• 6% Safety and Environment• 12% Professional DevelopmentDomain Performance Analysis Grid after every full-length exam. Know exactly which chapters to revisit before exam day — not after you've already sat in the testing chair.This book is for you if:• You need to pass the CCHT on the first attempt• You've used another prep book and found the questions too easy or the water treatment too thin• You know patient care on the floor but need to convert that into exam performance• You want a resource built from the actual NNCC blueprint — not a textbook repackaged as exam prepOther books will leave you guessing on exam day.
