Math Essentials for Medication Dosage Calculations

How to apply medical math fundamentals to solving medication dosage calculation problems

Have you ever said to yourself:

  • When I see word problems and scenarios, I freeze. I could really use a step-by-step explanation of the process.
  • Dimensional analysis? Using fractions to solve problems? I definitely need a math refresher.
  • I have an exam coming up and need some hands-on practice with solving dosage calculation problems.

If you have had similar thoughts, then this course is for you.

Don't Worry. This course is not about learning EVERY drug dosage calculation problem in existence. Instead, this course targets one specific topic that many beginning students find challenging—solving medication dosage calculation problems.

Read this problem:

A physician ordered 800 mg/kg of medication to be taken in equally divided doses four times per day for a pediatric patient who weighs 67.5 lbs. The medication is available in 3 g per capsule. How many capsules should the patient take per dose? Round to the nearest whole.

You may not realize it, but wrapped within this one problem, are several essential math concepts that you must first understand to solve the problem accurately. From rounding decimals to using multi-step dimensional analysis, this course covers the essentials, and gradually builds your skills so you can solve problems similar to the one above. As you progress through the course, you will encounter practice activities and quizzes for every concept presented to you—all tailored to help you solve dosage calculation problems commonly found on academic assessments.
