CPDN Training

TL;DR
  • The Certified Peritoneal Dialysis Nurse exam from BONENT has 150 multiple-choice questions and a 3-hour limit.
  • Nursing Process carries 60% of the exam, so most of your training time belongs there.
  • RNs need one year of nephrology experience; LPN/LVNs need two years plus active ESRD participation.
  • Passing means a scaled score of 70 on a 1-100 scale, not a verified 70% raw score.

What "CPDN Training" Actually Covers

When nurses search for CPDN training, they usually mean one of two things: the clinical training that builds peritoneal dialysis competence, or the exam preparation that gets them through the credentialing test. For the Certified Peritoneal Dialysis Nurse credential, both matter, but they are not the same thing. Clinical training happens at the bedside and in the home dialysis clinic. Exam preparation happens at your kitchen table with the published blueprint in front of you.

The credential is issued by the Board of Nephrology Examiners Nursing and Technology (BONENT). It is a nursing certification for peritoneal dialysis, which means the exam tests how you assess, plan, teach, and document in a PD setting. It is not the CHT technician examination, and it is not a different dialysis-nursing credential. If you want the broader picture of what the credential represents before you plan your training, the overview at What Is CPDN Certification? is a good starting point.

This article treats training as a sequence: confirm you qualify, learn how the exam is built, align your clinical experience and study time to that structure, and then handle the practical mechanics of applying and testing.

Start With the Experience Requirement

Unlike many nursing exams, you cannot simply study and sit for this one. BONENT requires documented nephrology experience, and that experience is itself the first stage of your training. The clinical hours you accumulate before applying are what the exam questions are drawn from.

RequirementRN RouteLPN/LVN Route
LicenseValid nursing licenseValid license
Nephrology experienceAt least 1 yearAt least 2 years
Facility participationActive participation in an ESRD facilityActive participation in an ESRD facility

Two details are easy to miss. First, applications require two signed, dated references: one from your immediate supervisor and another from a nephrology professional. Line up those people early, because their signatures are a gating item. Second, BONENT publishes an exception for qualifying unemployed applicants, who may document experience through their immediate past supervisor. If you are between jobs, that exception keeps the door open.

For a fuller walk-through of eligibility, see CPDN Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Training implication: If you are still accumulating your experience year, use it deliberately. Ask to be involved in PD patient assessments, training sessions, and exit-site and peritonitis follow-up rather than only hemodialysis tasks. Those exposures map directly onto the heaviest exam domain.

Let the Exam Blueprint Direct Your Training

BONENT publishes the content outline for this exam as Certified Peritoneal Dialysis Nurse - Detail of Examination Content. The four domains below are formal examination objectives with official weights. They describe how the exam is built, not how much time a course must allocate, but they are still the best guide to where your effort pays off.

DomainExam Weight
Domain 1: Nursing Process60%
Domain 2: Administration10%
Domain 3: Education20%
Domain 4: Professional Development10%

On a 150-question exam, those weights mean the large majority of questions come from Nursing Process, with Education a distant but meaningful second. Administration and Professional Development together account for a fifth of the content. A candidate who splits study time evenly across four domains is quietly under-preparing for the part that decides the outcome.

For a domain-by-domain breakdown, see CPDN Exam Domains 2026: Complete Guide to All 4 Content Areas.

Training for the 60% Domain: Nursing Process

Nursing Process is where clinical training and exam training overlap most. The domain follows the logic nurses already use at the bedside: assess, identify problems, plan, implement, and evaluate. In a PD context, that means you should be able to reason through situations rather than recite definitions.

Domain 1: Nursing Process (60%)

Expect scenario-style questions that ask what a PD nurse should assess, do, or teach next. Strengthen the following areas through both clinical exposure and review:

  • Patient assessment before and during PD therapy, including volume status and signs of complications
  • Peritoneal access care and exit-site assessment
  • Recognizing and responding to peritonitis and other infectious complications
  • Dialysis prescription concepts, including exchange types and how adjustments affect clearance and ultrafiltration
  • Interpreting laboratory results and adequacy information in a PD patient
  • Medication considerations and nutrition issues specific to PD patients
  • Troubleshooting mechanical problems such as drainage or inflow difficulties

The best preparation here is applied. When you encounter a PD patient with a change in effluent or a concern at the exit site, walk through your reasoning step by step and ask what the next nursing action is and why. That habit mirrors how the questions are framed.

Key Takeaway

Because Nursing Process dominates the exam, treat every real PD patient encounter as a practice question. Rehearse assessment, intervention, and evaluation in that order, and you are training for the largest slice of the test.

Training for Education: Teaching Patients and Partners

Education is the second-heaviest domain at 20%, and it is the one many experienced nurses underestimate. Home dialysis lives or dies on patient and caregiver competence, so the PD nurse is first of all a teacher.

Domain 3: Education (20%)

Be ready for questions about how you teach, assess learning, and reinforce safe technique.

  • Adapting teaching methods to different learners and settings
  • Teaching aseptic technique and exchange procedures
  • Evaluating whether a patient or caregiver has actually learned a skill
  • Teaching recognition of complications and when to call the clinic
  • Reinforcing adherence and addressing barriers to home therapy

If your clinic has a formal PD training program for new patients, volunteer to observe or assist. Watching how a skilled trainer sequences instruction and checks understanding is more valuable than reading about it.

Administration and Professional Development

Together these two domains make up 20% of the exam, split evenly at 10% each. They are smaller, which makes them efficient to learn well. A focused review can lock in most of these points.

Administration (10%)

Expect questions about how a PD program runs: documentation, quality monitoring, regulatory and safety awareness, and coordination of care. Think about the processes that surround patient care rather than the care itself, including how outcomes are tracked and how problems are reported and addressed.

Professional Development (10%)

This domain addresses your growth and accountability as a nurse: scope of practice, ethical conduct, continuing education, and staying current with practice standards. These items tend to reward careful reading and sound professional judgment.

Efficiency note: Because these two domains are compact, a few focused study sessions usually go further than the same time spent re-reading material you already know well. Use your review of them to find your genuine gaps.

Application and Registration Mechanics

Training is not only about knowledge. Plenty of well-prepared nurses lose time because they mishandled the administrative steps. Here is what the process looks like.

  1. Confirm eligibility. Verify your license status, your nephrology experience, and your active ESRD facility participation.
  2. Gather your two references. One must come from your immediate supervisor and one from a nephrology professional, both signed and dated.
  3. Choose your testing mode. Paper-and-pencil or center-based computer-based testing (CBT).
  4. Submit your application and fee. The current United States fees are $235 for paper testing and $255 for CBT.
  5. Receive your confirmation letter. CBT candidates must test within six months of that letter.

BONENT's official CBT center directory is hosted at smttest.com, so use that to locate a testing center convenient to you. Fee schedules change, so always check the current BONENT eligibility and fees page before paying, because older handbook prices are superseded by the current pages.

Training for the Format: 150 Questions in 3 Hours

The exam contains 150 multiple-choice questions and allows 3 hours. That works out to roughly 72 seconds per question on average, which is comfortable for recall items but tighter for multi-step clinical scenarios. Your training should include timed practice so that pacing feels natural before test day.

Two points about scoring are worth understanding before you start practicing:

  • Passing requires a scaled score of 70 on a 1-100 scale. This is not a verified 70% raw-score threshold, so do not assume that answering 70% of questions correctly guarantees a pass.
  • On computer-based testing, the interface permits question review and answer changes, so you can flag uncertain items and return to them.

Because scoring is scaled, the sensible goal is not to hit a particular raw percentage but to build solid, broad competence, especially in Nursing Process. For more on how the score works, read CPDN Passing Score 2026: Exactly What You Need to Pass, and if you are wondering about difficulty, see How Hard Is the CPDN Exam? Complete Difficulty Guide 2026.

Realistic question practice is the most direct way to build pacing and pattern recognition. The practice questions on the main CPDN practice test site are designed around this exam's domains and format, which makes them a good fit for the timed-practice phase of your training.

A Domain-Weighted Training Schedule

If you want a structured plan, weight your weeks by the blueprint rather than splitting time evenly. This is one example for a nurse who already meets the experience requirement and has a few months to prepare. Adjust the length to your own situation.

Weeks 1-2

Blueprint review and Nursing Process foundations

  • Read the BONENT examination content outline and mark topics you feel weak on
  • Begin with assessment, access care, and infectious complications
  • Take a short diagnostic quiz to establish your starting point
Weeks 3-5

Deepen Nursing Process

  • Work through prescription concepts, adequacy, labs, and troubleshooting
  • Practice scenario questions that ask for the next best nursing action
  • Review missed questions and note the underlying concept, not just the answer
Week 6

Education domain

  • Review teaching principles, learner assessment, and patient training content
  • Connect each concept to a real training scenario from your clinic
Week 7

Administration and Professional Development

  • Cover documentation, quality, scope of practice, and ethics
  • Use this lighter week to find any remaining gaps
Week 8

Timed practice and consolidation

  • Complete full-length 150-question sets in 3 hours
  • Re-study only the areas where your results show weakness

Exam-Day Rules That Shape Your Preparation

Knowing the rules in advance removes avoidable stress. Testing is closed book, and you must bring your confirmation documents and approved identification. Personal books, calculators, and electronic devices are prohibited.

That last point matters for training. Any dosing, volume, or clearance reasoning you practice should be something you can do without a calculator. If you rely on a calculator during study, shift to working problems by hand so the exam does not catch you off guard. Review the BONENT day-of-exam page and the Candidate Handbook before your test date, remembering that current fee pages take precedence over the handbook's older prices.

Practical reminder: Check your identification and confirmation documents the week before the exam, not the morning of. A mismatch in a name or a missing document is a preventable reason to be turned away.

After You Pass: Staying Certified

Certification renews every four years, so training continues after the exam. The 2026 Recertification Booklet requires 40 contact hours, including at least 30 nephrology-related Group A hours. Alternatively, you can retake the examination, or use a once-in-a-lifetime continuing-education waiver. Maintenance fees remain payable even under the waiver.

On the cost side, annual maintenance is $65, or $240 when four years are prepaid. Routine recertification carries no additional processing fee when maintenance requirements are met, although the examination route requires its own examination fee. Building a habit of logging nephrology-focused continuing education from the start makes renewal painless.
