## Summary

"Add a dimension to your knowledge. With Curren's Dimensional Analysis for Meds, Third Edition, you find out just how easy it can be to calculate dosages correctly. No prior knowledge of calculation is necessary, as a building-block organization is employed to cover basic facts and tips regarding drug measures, reading medication labels, and syringe calibrations. Once competency is established, more complex concepts are presented, such as intravenous and pediatric calculations, as well as numerous opportunities to practice your new skills. A conversational style accompanies this effective learning progression, revealing Dimensional Analysis for Meds as simply the most effective tool for learning dosage calculations."--BOOK JACKET.
