A physician orders 15 ml of Brand X Antacid Suspension to be taken four times daily. How many days will a 12 oz. bottle last?

To determine how long a 12 oz. bottle of antacid suspension will last when a patient is instructed to take 15 ml four times daily, we must first calculate the total daily dosage and then compare it to the total volume of the bottle.

A 12 oz. bottle is equivalent to approximately 355 ml, since 1 ounce is about 29.57 ml. Next, we calculate the total amount of suspension the patient consumes each day:

15 ml per dose multiplied by 4 doses per day equals 60 ml per day.

Now that we know the patient consumes 60 ml daily, we can find out how many days the bottle will last by dividing the total volume of the bottle by the daily consumption:

355 ml (total volume of the bottle) divided by 60 ml (daily consumption) equals approximately 5.92 days.

Since we’re looking for whole days, we need to round down, which leads us to 5 days. However, the correct approach is considering practical application in a pharmacy context where partial doses may still indicate service coverage or supply length; therefore, it may be customary to extend usage estimation to the next full day for planning purposes.

Thus, while it approximates into standard practical use that the medication
