For the prescription with Sig: 1 tab PO, BID x 14 days, then 1 tab BID prn, what is the minimum number of tablets?

Explanation:
The main idea here is calculating total tablets based on the dosing schedule and recognizing what “prn” means. For 1 tablet by mouth, twice daily (BID) for 14 days, you take 2 tablets per day. Over 14 days that’s 2 × 14 = 28 tablets. After that period, the prescription says 1 tablet BID prn, meaning you may take up to 2 tablets per day as needed, but to find the minimum number, assume no additional tablets are taken during the prn phase. So the minimum total is 28 tablets.
