PRE- ORDER

Medical math makes more sense when you can explain how you got the answer.

You have the medication order. You have the label. Now you need to work through the calculation, keep the units straight, and check that your answer makes sense.

The Medical Math Survival Guide, Second Edition by Bryan Selvage helps you build those habits through clear explanations, worked examples, and practical exercises. Written for EMTs, paramedics, nurses, healthcare students, and critical care clinicians, this guide takes you from foundational number skills through pediatric dosing and critical care calculations.

Across 15 chapters, you will practice a repeatable approach to medication math: identify what you need, organize the information, solve the problem, and verify the result. Where applicable, worked solutions demonstrate dimensional analysis, Desired Over Have, and ratio and proportion, so you can compare methods and understand the reasoning behind the answer.

Inside, you will find:

• Essential foundations: Metric conversions, decimal placement, concentration language, and the units that keep your calculations organized.
• Medication-label practice: Simulated educational labels that help you distinguish total drug amount, total volume, and concentration, alongside a chapter on the seven rights of medication administration.
• Step-by-step clinical math: Body weight calculations, basic medication doses, weight-based dosing, reconstitution, dilution, IV drip rates, and infusion calculations.
• Pediatric and critical care calculations: Practice applying the same mathematical principles to more involved problems.
• Tools for learning and review: Chapter practice problems, student worksheets, review questions, explained answers, and one-page cheat sheets.
