A pharmacy technician is processing a prescription for 60 tablets of a medication. The instructions read, "1 tab po qid." What is the days' supply for this prescription?

To determine the days' supply for the prescription of 60 tablets with the instructions "1 tab po qid," we need to first understand what the instructions specify. The abbreviation "po" stands for "by mouth," and "qid" means "four times a day." This means the patient is instructed to take one tablet four times each day.

To calculate the total number of tablets used per day, multiply the frequency of doses by the number of tablets taken at each dose:

1 tablet per dose × 4 doses per day = 4 tablets per day.

Next, to find the total number of days the supply will last, divide the total number of tablets prescribed (60 tablets) by the number of tablets consumed each day (4 tablets):

60 tablets ÷ 4 tablets per day = 15 days.

Thus, the days' supply for this prescription is correctly determined to be 15 days. This is an important calculation for pharmacy technicians, as it helps ensure accurate dispensing and managing medication supply for patients.
