CVS Pharmacy Technician Certification Practice Test

What is the significance of the term "prn" in prescription directions?

1. As needed

2. Every hour

3. Twice daily

4. Only at night

The correct answer is: As needed

The term "prn" is derived from the Latin phrase "pro re nata," which translates to "as needed." This term is commonly used in medical and pharmaceutical settings to indicate that a medication should be taken only when necessary, rather than on a fixed schedule. In the context of prescriptions, the significance of "prn" is crucial for medications that are meant to relieve symptoms that may occur intermittently, such as pain relievers or anti-anxiety medications. It allows patients the flexibility to manage their medication intake based on their individual needs, effectively providing a tailored approach to treatment. Understanding this term is essential for a pharmacy technician, as it directly affects how medications are dispensed and the guidance provided to patients regarding when to take their medication. The other options suggest fixed dosages or specific times for medication, which do not align with the flexibility meant by "prn."
