An outpatient clinic RN performs a variety of healthcare duties at an outpatient clinic in a hospital or an ambulatory care center. In an outpatient clinic, a patient does not need to make an appointment to see a nurse or physician. Your specific responsibilities depend on the type of clinic at which you work. For example, if you work at a hospital outpatient facility, you perform medical screenings and diagnostics and collect patient histories, which help you determine the level of care each patient needs. You also provide referral services when you determine if a patient needs to go to a specialist’s office.
