CNRN case studies

CNRN · Put your knowledge to work in context.

The Certified Neuroscience Registered Nurse (CNRN) credential is a specialty nursing certification awarded by the American Board of Neuroscience Nursing (ABNN) and accredited by the Accreditation Board for Specialty Nursing Certification (ABSNC). ABNN describes it as a marker of knowledge of neuroscience nursing fundamentals and a generalist exam that is not intended to emphasize any particular level of care or developmental level - so it applies to nurses in intensive care, step-down, general neuro, rehabilitation, and outpatient roles alike. The CNRN case studies are 5 cases and about 2,102 words.
