Part C If the patient has to be administered a dosage of 2 tablets every 8 hours for 7 days, what is the number of tablets required for the prescribed dosage? Express your answer as a whole number.

To find the total number of tablets required, we start by determining the total doses per day. The patient takes 2 tablets every 8 hours, which means 3 doses in a day (24 hours ÷ 8 hours = 3). Over 7 days, that amounts to 3 doses/day × 7 days = 21 doses. Each dose is 2 tablets, so the total number of tablets needed is 21 doses × 2 tablets/dose = 42 tablets. Therefore, the patient will need 42 tablets for the prescribed dosage.
