In the United States, the certified nursing assistant (CNA) typically works in a nursing home or hospital, and performs everyday living tasks for the elderly, chronically sick, or rehabilitation patients who cannot care for themselves.
Some hospitals and nursing homes also offer CNA programs. Each state regulates the specific requirements for CNA programs. Upon completion of the educational program, CNAâs must take a competency examination that allows them to use the title Certified Nursing Assistant.
