CHT exam — 6 months out, building my study plan now

Passed with an 80% after 5 months of prep. The machine troubleshooting scenarios were harder than clinical questions for me — know your alarms and what each one means mechanically.

Patient assessment and complication recognition come up a lot. Know when to call the nurse, when to slow the treatment, when to stop. Those judgment calls are heavily tested.

Renal physiology is foundational — if you understand why dialysis works you can reason through questions rather than memorizing every detail. Don't skip the theory.

Water treatment and dialysate preparation questions are dense and worth a lot. Start there. It's where most techs have gaps because it's handled by someone else at many facilities.

Six months is honestly more than enough if you don't waste the first two. I passed in April and the thing that actually moved the needle for me was drilling practice questions way earlier than I thought I needed to. I kept reading and re-reading my BONENT study guide but I wasn't retaining anything until I started testing myself daily. Found a set of free hemodialysis technologist questions online and just worked through them every morning before my shift. That's when I realized which topics I actually understood versus which ones I just thought I understood.

Water treatment and machine troubleshooting were my weak spots and I'm glad I found out at month two, not month five. You've got time to fail a bunch of practice tests and still be fine. Use it.

Six months is actually a really good runway for CHT if you use it the right way. The thing that helped me most wasn't just grinding questions -- it was making sure I understood why the wrong answers were wrong. Like, if you're getting a question about Kt/V and you eliminate three options, can you explain what's actually incorrect about each one? If you can't, you don't really own the concept yet. I started using free hemodialysis technologist questions early on just to identify my weak spots, not to rack up a score.

Two years of floor experience is going to help more than you think, especially with the clinical stuff. But the exam goes deeper on water treatment and machine mechanics than most outpatient centers actually drill you on day-to-day, so don't assume you've got those locked just because you've done the job. Hit those areas hard and keep asking yourself why each distractor is wrong -- that habit alone changed how I retained the material.
