Certified Nephrology Nurse (CNN) Nephrology nursing demands simultaneous mastery of dialysis mechanics, fluid-electrolyte physiology, and psychosocial care—a tighter integration than most specialties. The CNN exam reflects this complexity by testing real-world triage scenarios where a single miscalculation in potassium levels cascades into clinical crisis. Nurses prepping for this credential must synthesize vascular access management with medication pharmacokinetics in ways that general nursing exams never require.
