A Certified Nursing Assistant (CNA) plays a crucial role in healthcare, providing essential daily care, monitoring, and emotional support directly to patients and residents. Working under the supervision of Registered Nurses (RNs) and Licensed Practical Nurses (LPNs), CNAs are key observers for the healthcare team. They assist individuals who are ill, recovering from surgery, or experiencing cognitive or physical decline due to aging with activities such as bathing, dressing, eating, and maintaining hygiene. CNAs' frequent one-on-one interactions enable them to notice vital sign changes, skin issues, or mood shifts early, often preventing serious complications.
