A Certified Nursing Assistant (CNA) is a healthcare professional who provides essential support to patients in various settings, such as hospitals, nursing homes, and assisted living facilities. CNAs assist with daily activities, including bathing, dressing, and feeding patients, while also monitoring their vital signs and reporting any changes to nursing staff. To become a CNA, individuals must complete a state-approved training program and pass a certification exam. This role is crucial in the healthcare system, as CNAs help ensure that patients receive the care and attention they need, contributing to their overall well-being and comfort.
