What does prn mean?

• A. as needed
• B. prior to arrival
• C. patient
• D. put to sleep

Answer: (A)

PRN stands for pro re nata, Latin for “as needed.” In veterinary care, it means giving a medication or performing an intervention only when the patient requires it, not on a strict schedule. For example, a pain medication might be given PRN if the animal shows signs of pain, or an antiemetic PRN if vomiting occurs. It’s about responding to the animal’s current condition rather than delivering doses at set times, and it’s not about arrival timing, the patient itself, or putting the patient to sleep.
