BONENT CHN

No. We are an independent study platform. We do not issue the CHN, administer the exam, approve applications, or speak for BONENT. All official decisions about eligibility, scheduling, scoring and recertification rest with BONENT and are published in its Candidate Handbook and exam pages.

BONENT lists two delivery methods for its certification exams: Paper & Pencil Exams (PPE) and Computer Based Testing (CBT). The CHN page we retrieved did not state which methods apply specifically to the CHN, so confirm your options and any scheduling differences in the current Candidate Handbook before you apply.

We cannot state these numbers accurately. The CHN page returned a 404 at retrieval and contained no item count or time limit, so we report them as unknown rather than guess. Check the current CHN page or the Candidate Handbook, and rehearse with timed sets once you have the official figures.

We do not publish a passing score because the permitted source did not state one. Passing standards are set by BONENT and can change between handbook editions. Use the Candidate Handbook or the Exam Results page as your only source, and treat any third-party claim of a specific cut score with suspicion.

BONENT maintains a Retake Exam page under its "After Exam" section, so a retake pathway exists. The waiting period, fee and application requirements are not stated on the pages we were able to retrieve. Read that page and the Candidate Handbook before assuming a timeline for your second attempt.

BONENT routes applications through its Application & Deadlines page and fee information through Eligibility & Fees. BONENT also notes a new expedited exam application process effective as of 2/1/24. Start with those two pages, then confirm your application status through the online status checker rather than emailing to ask.

Start with renal anatomy, physiology and pathophysiology, because indication, adequacy and complication questions all rest on it. Move next to the extracorporeal circuit and machine operation, then water treatment and dialysate, which are frequently under-studied. Finish with clinical practice and infection control, drilling those in short mixed sets so recall survives the exam day.

Three patterns dominate. First, memorizing unit-specific policy instead of underlying principles, which fails when a question is phrased abstractly. Second, skipping water treatment and dialysate because they feel like a technician's job. Third, knowing normal values without knowing the action to take when they are abnormal, which is usually what the item actually asks.

We cannot state the recertification cycle because the CHN page we retrieved did not include it. BONENT maintains a Recertification Overview, a How-To and How Often page, a Contact Hours/CEUs page and a Lapsed or Expired Certification page. Those are the correct places to confirm your cycle and continuing education requirements.

BONENT's executive office is at 100 S. Washington Street, Rockville MD 20850, phone (202) 462-1252, fax (202) 463-1257, with a contact form on its site. For certification verification or to check recertification status, BONENT provides an online verification tool through the member portal.
