A certified nurse assistant (CNA) assists individuals with their daily healthcare needs-including basic nursing procedures. A CNA’s job includes ambulation, applying anti-embolic stockings, output measurement, oral care, dressing, feeding, hair care, bed-making, nail care, bathing, positioning, range-of-motion exercises, and vital sign monitoring. It is also a stepping-stone to becoming an RN, whose annual salary can triple that of a CNA.
