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.
