Answer :
Final answer:
A 16-oz bottle of antacid will last for 24 days if a patient takes 4 teaspoons per day, according to the given dosage.
Explanation:
The question is asking how long a 16-oz bottle of antacid will last if a patient takes 1 teaspoon (tsp) three times a day (tid) and 1 teaspoon (tsp) at bedtime. One ounce is equivalent to 6 teaspoons. Therefore, a 16-oz bottle contains 96 teaspoons (16 oz × 6 tsp/oz). The patient takes a total of 4 teaspoons of antacid a day (3 tsp tid + 1 tsp at bedtime). To find out how many days the bottle will last, divide the total number of teaspoons in the bottle by the number of teaspoons taken daily: 96 teaspoons ÷ 4 tsp/day = 24 days. Thus, the 16-oz bottle of antacid will last for 24 days.
