Overnight Prn RNs typically work scheduled overnight shifts on an as-needed basis, often in hospitals or long-term care facilities. Per Diem RNs also work on an as-needed basis but may have more flexible scheduling across various settings. Both roles require RN licensure and similar certifications, but the main difference lies in scheduling and employment structure.
