Master math concepts. Ensure patient safety. Prevent medication errors.
Help students conquer their fears and understand the most common math concepts used in nursing practice today. Color-coded, step-by-step guidance shows students how to accurately calculate drug dosages using all four methods. They’ll begin with a basic math assessment and then explore in-depth coverage of complex topics, including intake and output, parenteral intake, NG tube feeding strength, and labeling IVs.
Build confidence with thousands of practice questions in the text and online at FADavis.com. An access code inside new, printed texts unlocks the tools for course success.
Makes medical math easy to understand. “Wow this book has been a lifesaver throughout nursing school for dummies like me who aren’t so great at math. Highly recommend if you’re in nursing school or any profession that requires you to calculate drug dosages. Also this book isn’t just the math portion....It teaches you about the basic things about the drugs, drug information, safety, how to read the labels, etc.”—IT, Online Reviewer
“The text Calculating Drug Dosages is very helpful in teaching dimensional analysis. I was able to help 4th semester students with their clinical drug test achieve 100% with the examples in the book! I would recommend this text for beginning and advanced RN students.” —Pamela Vogel, RN, MSN, WHNP, Fresno City College
