A prescription calls for 35 mg per dose, 3 times a day for a particular drug. The pharmacist only has 12.5 mg tablets. How many tablets must you take per dose?
To determine how many tablets you need to take per dose, you first need to calculate the total amount of drug required for one dose.
The prescription calls for 35 mg per dose, and since the pharmacist only has 12.5 mg tablets, you must calculate how many tablets are needed to reach the required dose.
To do this, divide the required dose (35 mg) by the strength of one tablet (12.5 mg) to find out how many tablets are needed for one dose:
35 mg / 12.5 mg = 2.8 tablets
Since you cannot take a fraction of a tablet, you would need to round up to the next whole number to ensure you are taking an adequate amount of the drug.
Therefore, you would need to take 3 tablets per dose in order to reach the required dosage of 35 mg.
