What does PRN mean in medical terminology?

• A. Prior to needing
• B. As required
• C. Patient rest necessary
• D. Give as needed

Answer: (D)

PRN is a widely recognized abbreviation in medical terminology that stands for "pro re nata," which is a Latin phrase meaning "as needed." This term indicates that a medication or treatment should be administered only when necessary, rather than on a fixed schedule. The phrase recognizes the situational nature of certain medical interventions. For example, a patient might take pain medication PRN, meaning they should self-administer the medication when they feel they require relief. This allows flexibility in treatment, accounting for varying patient needs over time rather than enforcing a standard dosage. While "give as needed" is synonymous with the intended meaning of PRN, "as required" captures a similar essence, which might lead to some confusion. However, the specific phrasing of "give as needed" aligns perfectly with standard usage and understanding within medical settings, reinforcing the direct connection to patient care protocols.
