Clinical Nurse Specialist (CNS)

Defined by National Association of Clinical Nurse Specialists: Clinical nurse specialists are advanced practice registered nurses who have graduate preparation (Master’s or Doctorate) in nursing. Like other advanced practice registered nurses, they are trained in advanced physiology, pharmacology and physical assessment in addition to their particular areas of specialty. They can diagnose, treat, prescribe and bill like other APRNs as allowed by their state regulations (2022).
