Dosage Math第 60 / 100 题
The order is 0.5 g of a medication. The tablets available are 500 mg each. How many tablets are needed? (First convert 0.5 g to mg.)
a.1 tablet
b.2 tablets
c.5 tablets
d.1/2 tablet
解析
Convert grams to milligrams: 0.5 g × 1000 = 500 mg, then tablets = 500 mg ÷ 500 mg = 1 tablet. Converting to the same unit before dividing prevents serious dosing errors.
