Question
You need to administer 250 mg of erythromycin (Erythrocin) PO. You have on hand 0.5 g tablets. How many tablet(s) will you give
Solution
First, you need to convert the dosage you have on hand from grams to milligrams because the dosage you need to administer is given in milligrams.
1 gram (g) is equal to 1000 milligrams (mg). So, 0.5 g is equal to 0.5 * 1000 = 500 mg.
You have 500 mg tablets on hand and you need to administer 250 mg.
To find out how many tablets you will give, you divide the dosage you need to administer by the dosage you have on hand per tablet.
So, 250 mg / 500 mg = 0.5 tablet.
Therefore, you will give 0.5 tablet of Erythrocin.
