PRN in Any Field. You can be a PRN employee in any medical-related field. Many PRNs are therapists, nurses or nursing aides. But many other medical areas also use PRN employees to fill in as needed as laboratory workers, therapists, sleep technicians or other medical specialists.
As of 2014, PRN positions are budgeted positions that are often considered temporary employment. Employees who work in PRN positions are not eligible for most employment benefits, such as paid time off, life insurance and medical health plans. In lieu of benefits, some employers offer increased wages to PRN employees.
