A certified medication aide (CMA) is a professional with certified nursing assistant qualifications and an additional certificate that lets them dispense medication to patients. Certified medication aides receive supervision from a Registered Nurse (RN) while on the job, assisting health care staff with following up on patient medications and dosing. A medication aide tracks prescription and non-prescription drugs that they administer to patients. Accurately documenting dosage times and amounts, as well as ensuring that patients swallow their medication, are primary duties of a CMA job. When you are not serving as a medication aide, you will revert to the duties of a CNA and continue to care for patients.
