Exam Overview
The Certified Peritoneal Dialysis Nurse (CPDN) Exam is a professional certification designed for nurses who specialize in the care of patients receiving peritoneal dialysis treatment. The certification confirms that a nurse has the clinical knowledge required to manage dialysis procedures, monitor patient safety, and provide patient education.
Peritoneal dialysis is a common treatment for individuals with End-Stage Renal Disease (ESRD). Nurses working in dialysis units must understand renal physiology, dialysis techniques, infection control practices, and patient management strategies. The CPDN certification evaluates a nurse’s ability to apply this knowledge in clinical practice.
Earning this credential demonstrates professional competence in nephrology nursing and supports high standards of care for patients undergoing dialysis treatment.
Administering Organization
The CPDN certification is administered by the Board of Nephrology Examiners Nursing and Technology (BONENT).
BONENT is a professional organization that develops certification programs for healthcare professionals involved in dialysis treatment. The organization establishes exam standards, evaluates clinical competencies, and promotes quality care in nephrology practice.
BONENT certifications are recognized in dialysis facilities, hospitals, and renal care programs throughout the United States.
