A certified nursing assistant has the responsibility for serving the needs of their patients while under the supervision of a licensed nurse. Certified Nurse Assistants are the liaison between the patient and the licensed nurse. The CNA’s primary responsibility is to take care of the patient’s personal and healthcare needs as well as communicate critical information about the patient’s health. A CNA may work in various healthcare facilities such as hospitals, assisted living facilities, nursing homes, or even personal homes. The work is fast-paced, and CNAs must have a strong work ethic to be successful.
