1 Do not attempt to remove visible debris or drainage from the ear. 2  Stop swimming or exposure to water until the condition improves.  Apply heat to the ear to control the pain at home.

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.
PRN is Latin for pro re nata, which would mean that a person hired for a specific job will be needed as circumstances arise, and that he/she will not be subject to a standard or set working schedule. PRN jobs are as needed. The employee is not guaranteed a schedule or set hours, but rather, works when needed.
