What is a CNS?

A Clinical Nurse Specialist (CNS) is an Advanced Practice Registered Nurse (APRN) prepared by a master’s, doctoral, or post-graduate certificate level CNS program. CNSs diagnose, prescribe, and treat patients and specialty populations across the continuum of care. The CNS improves outcomes by providing direct patient care, leading evidence-based practice, optimizing organizational systems, and advancing nursing practice.
