As a CNA, your responsibilities center around patient care. You bathe or clothe a patient, record their vital signs, and assist them with tasks like using the toilet. Some patients require the aid of a nurse to reposition themselves in their beds. You may need to answer questions, perform examinations, and serve meals as part of your duties. Communicating with other medical staff about the patient is also a part of your job description. During a night shift, you may be the only CNA assisting one or several patients. Night shifts usually operate with fewer employees, placing more responsibility on you and your skills.
