Calculation:
Total tablets = 28 tablets.
- Calculate the number of tablets to be taken per day.
The order is to take 1 tablet every 6 hours ("q6h").
Number of doses per day = 24 hours / 6 hours/dose
= 4 doses per day.
Since each dose is 1 tablet, the patient takes 4 tablets per day.
- Calculate the total days' supply.
Days' supply = Total tablets / Tablets per day
= 28 tablets / 4 tablets/day
= 7 days.
