What does "Prn" signify in the context of medication dispensing?

1. Prompt delivery

2. Prescription required now

3. As needed

4. Prior review necessary

The correct answer is: As needed

"Prn" is a medical abbreviation derived from the Latin phrase "pro re nata," which translates to "as needed." In the context of medication dispensing, this term indicates that a medication should be administered only when required, not on a scheduled basis. This allows for flexibility in treatment based on the patient's symptoms or condition at any given time. The other interpretations provided in the options do not accurately reflect the meaning of "Prn" within the medical field. They suggest specific conditions for medication administration that do not align with the concept of variability in dosage as needed for patient comfort and care.
