What’s on the CHT cheat sheet
- Patient Care (45%) — dialysis principles (diffusion, ultrafiltration, convection), vascular access and cannulation, fluid management and dry weight, intradialytic complications, and key labs — the largest domain by far.
- Infection Control (18%) — standard and dialysis-specific precautions, bloodborne pathogens, isolation for hepatitis B, and a clean, safe treatment environment.
- Water Treatment (15%) — the purification train (carbon tanks, reverse osmosis), AAMI chemical and microbiological limits, and dialyzer reprocessing.
- Machine Technology (12%) — the extracorporeal blood circuit, dialysate and conductivity, machine setup, and the alarms that protect the patient.
- Education & Professional Development (10%) — scope of practice, the care team, patient education, documentation, communication, and QAPI.
How to use it in your final week
- Front-load Patient Care — it's 45% of the exam. If you master one domain from the sheet, make it dialysis principles, vascular access, fluid management, and complications.
- Drill the diffusion-vs-ultrafiltration distinction until it's reflex: diffusion clears wastes (solute), ultrafiltration removes fluid (water) under transmembrane pressure.
- Memorize the emergency responses cold — air embolism is left-lateral with head and chest down; hemolysis means stop, clamp, and don't return the blood.
- Read the sheet the morning of the test, then take one timed practice set (150 questions in 3 hours ≈ 72 seconds each) to keep your pacing sharp.
The cheat sheet is your review layer — your CHT practice test drives the exam-readiness ring at the top of this page. Download it, review, then take a full practice exam (or drill with the study guide and flashcards) to see where you stand.
CHT cheat sheet FAQ
Yes — the CHT cheat sheet downloads as a PDF at no cost and with no sign-up. It sits alongside Career Employer's free CHT practice test, study guide, and flashcards, so your entire BONENT prep stack is free.
It condenses the highest-yield facts BONENT tests into a quick reference organized by the five exam domains: Patient Care (45%), Infection Control (18%), Water Treatment (15%), Machine Technology (12%), and Education & Professional Development (10%). Think dialysis principles, vascular access, fluid management, complications, the water-treatment train, and machine safety checks.
It mirrors the five BONENT domains and their weights so nothing high-yield is missed, but it is a review layer, not a textbook. Use it to lock in facts fast, then reason through scenario questions with the practice test — the CHT rewards clinical judgment over memorization.
No — the cheat sheet is a cram and last-week review aid, not a substitute for working practice questions. You need a scaled score of 70 (on a 1–100 scale) to pass 150 questions in 3 hours, so pair the sheet with full-length practice, especially on Patient Care, where most points are won or lost.
