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.
While support from PRN staffing helps to cut overtime at times when patient demand increases, nurses are among the most common type of per diem employees. Hospitals routinely use PRN staffing when they are short-staffed or employees are out sick. PRN salaries vary widely based on job type, location and experience.
