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.
The term PRN is a shortened form of the Latin phrase pro re nata, which translates roughly as as the thing is needed.PRN, therefore, means a medication that should be taken only as needed. Pain medicines, sleeping pills, and cough medicines are common examples of PRN medicines.ost blood pressure medications are taken as a preventive method or for controlling the rise of blood pressure. In light of this, a pro re nata (PRN) order from your doctor or â¦ cardiologist is unlikely. However, if the medication is for controlling acute systems of blood pressure, it is usually used pro re nata.
