A telemetry nurse is an RN who monitors patient vital signs using electronic monitoring equipment, such as an electrocardiogram or EEG. Job duties include connecting the patient to a machine, recording all readouts, and discussing results with other health care professionals. A telemetry nurse usually works with patients that have gastrointestinal issues, heart disease, diabetes, or other acute illnesses. Additional duties may include consulting with the patient’s physician about treatment and medication, and administering medications while the patient is in the hospital.
