Medication Math (Med Math) Practice Exam

Question: 1 / 400

A milligram is abbreviated as?

mg

A milligram is abbreviated as "mg." This abbreviation is derived from the metric system, in which "milli-" means one thousandth. Therefore, one milligram is one thousandth of a gram. The use of "mg" is important for clarity and accuracy in medication dosing, as it helps healthcare professionals quickly understand and communicate the correct quantity of medication being prescribed or administered.

Other options represent different units of measurement. "mcg" stands for microgram, which is one millionth of a gram. "g" indicates grams, which is a larger unit of mass than milligrams. "lb" denotes pounds, which is a unit of weight primarily used in the United States and is not part of the metric system. Understanding these distinctions is essential in medication math to avoid potential dosing errors.
