STNA stands for State Tested Nurse Aide, which is a required certification for anyone who wants to work as a nursing assistant in Ohio. An STNA works alongside nurses, doctors, and other healthcare providers to serve patients through personal care. This includes bathing, feeding, dressing, monitoring vital signs, and other similar tasks. To become an STNA you must complete state-approved training classes and then pass the STNA exam. In most other states this license is called Certified Nursing Assistant, or CNA.
