A certified nursing assistant (CNA) is known by different names in different states such as Patient Care Assistant (PCA), State Tested Nurse Aide (STNA), or Nurse Aide (NA). CNAs really hold an important place in the field of medicine because they assist the registered nurses and the licensed practical nurses in taking care of the patients. Though the role played by CNAs is very critical during patient care, they are legally restricted to perform certain medical procedures. Nurse aides keep direct contact with the residents or clients, and hence, their behavior and way of care impact the patient’s health.
