Dedication
Math for Nurses was fi rst published in 1987. 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!

Preface
T
he idea for this compact, pocket-sized book about
dosage calculation was generated by my students. 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.

quick access to specifi c information needed to administer
