Q: Are you associated with the Bonent or Nephrology Nursing Certification Commission?

A: No, DPT, LLC is not affiliated with or endorsed by any official testing organization. All organizational and test names are trademarks of their respective owners. (CCHT, CHT, CCNT)

Q: Are your exam questions exactly like the Bonent or Nephrology Nursing Certification Commission?

A: No, it is a violation of exam policy to attempt to recreate test questions from the exam. Our questions are in the same format as the Bonent exam and were derived from current:

• National Kidney Foundation (NKF)
• Kidney Disease Outcomes Quality Initiative (K/DOQI™ (NKF)
• US Renal Data System (USRDS)

• National Kidney Disease Education Program (NKDEP)
• National Institutes of Health (NIH)
• The Kidney & Urology Foundation of America (KUF)
• American Society of Nephrology (ASN)
for the CCHT / CHT or CCNT along with our own experiences as Dialysis Technician.
We then verified that each answer could be substantiated using current text and course material for CCHT/ CHT or CCNT.
