Final answer:
The patient's 16-ounce bottle of antacid, taken at a rate of 4 tsp per day, will last for 24 days, which is not one of the given options.
Step-by-step explanation:
To calculate how long a 16-ounce bottle of antacid will last when a patient is instructed to take 1 teaspoon (tsp) three times a day (tid) and 1 tsp at bedtime, we need to determine the total daily consumption and then divide the total amount in the bottle by this daily dosage.
First, we calculate the daily dosage:
- 1 tsp tid = 3 tsp per day
- 1 tsp at bedtime = 1 tsp per day
Total daily dosage = 3 tsp + 1 tsp = 4 tsp per day.
Since there are 6 teaspoons in an ounce, the 16-ounce bottle contains:
16 ounces × 6 tsp/ounce = 96 teaspoons in the bottle.
Next, we divide the total number of teaspoons in the bottle by the daily dosage to find how many days the bottle will last:
96 tsp ÷ 4 tsp per day = 24 days.
Therefore, the answer is not given in the options provided (a) 8 days, (b) 12 days, (c) 16 days, (d) 20 days. The patient's 16-ounce bottle of antacid will last for 24 days.
