A CNA (Certified Nursing Assistant) is a healthcare professional who provides basic care to patients in hospitals, nursing homes, and other healthcare settings. CNAs work under the supervision of registered nurses (RNs) or licensed practical nurses (LPNs) and assist with tasks such as bathing, dressing, feeding, and toileting patients. They also monitor vital signs, report changes in patient conditions, and provide emotional support to patients and their families. Sources and related content
