What does PRN stand for in the nursing field?

In the nursing field, a PRN is an on-call or temporary nurse who is not a regular staff member. This position may be used to cover maternity or extended sick leave, increase staffing during a pandemic, or fill less desirable shifts. PRN stands for "pro re nata," meaning "as the situation demands" in Latin. Some PRNs work through agencies and have consistent minimal hours, while others work on an as-needed basis.
