Your primary responsibilities are to assist other medical staff, such as doctors and nurses, and provide direct patient care and assistance with basic needs. You help patients take medicine and measure their vital signs. Hospital CNAs help move patients, clean wounds, and change bandages. You may also help patients with essential daily activities, such as bathing, eating, and grooming, while they are in the hospital.
