At that time I was a professor of nursing at Delaware County Community College. Brian was 7 years old, and Susan was 12 months old. This is now the eighth edition. I’ve dedicated previous books to my students, professional colleagues, friends, and family. However, over the years, it is my family who has continued to energize, support, and encourage my academic and creative interests. So, for this edition, I salute, honor, and thank my family again for always being there. Ermelina: my mother, who is 90 going on 75 Susan: a University of Richmond graduate, working in the fi nance world for the government in Washington, D.C. Brian: a mathematics high school instructor, pursuing two master’s degrees while also teaching at the college level Kristen: my new daughter-in-law, who embraces family and faith as life’s priorities Sadie: my darling granddaughter, whose laughter lights up all of our lives Bill: my husband and partner since 1974 Thanks Guys! iv LLWWBBKK991144--FFMM__ppii--xxvvii..iinndddd iivv 0088//1111//1111 66::2211 PPMM Contributors Brian D.

For sev- eral years I watched as they took their math-related handouts and photocopied them, reducing them to a size that would fi t into the pockets of their uniforms or laboratory coats. This “pocket” reference material was readily accessible when a math calculation was needed to administer a drug. Each year the number of papers that were copied increased as each group of students passed on their ideas to the next group. I also noted that staff nurses were using this readily available and compact information as a reference for math problems. When a student asked, “Why not put together for us all the information that we need?” I thought, “Why not?” The idea was born, the commitment made, and 18 months later the fi rst edition of Math for Nurses was published in 1987. It is my hope that it will continue, in this eighth edition, to be helpful to all who need a quick reference source when strug- gling with dosage calculations and drug preparation. How to Use This Book This book is designed for two purposes: • T o help you learn how to quickly and accurately calculate drug dosages and administer medications. • T o serve as a quick reference when reinforcement of learn- ing is required. The best way to use this pocket guide is to: • Read the rules and examples. • Follow the steps for solving the problems. • Work the practice problems. • W rite down your answers and notes in the margin so that you have a quick reference when you need to review. Organization This pocket guide is divided into three units to facilitate quick access to specifi c information needed to administer viii LLWWBBKK991144--FFMM__ppii--xxvvii..iinndddd vviiiiii 0088//1111//1111 66::2211 PPMM
