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. Warmth from a heating pad may provide some relief. Fold a towel in half and place it between the heating pad and the ear.
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.
Being in the right place at the right time can help you get a hospital job. If you work on a unit in a PRN job, you're already a familiar face. Your work ethic -- hopefully a good one -- is already known. When it's time to hire someone for a part-time or full-time position, your name may come up as a candidate.
