A certified nursing assistant helps feed and care for disabled adults. These are paraprofessionals supervised by the primary nurse. They help with patient care. Their duties include taking blood pressure and pulse, bathing, serving meals, assisting the patient with walking or getting out of bed, or turning the patient in bed. To learn these skills, CNAs attend at least 75 hours of classes. A CNA works under a nurse’s supervision and must keep taking classes to stay certified.
