The demands and hectic pace ofeveryday practice requires you to work efficiently; time management is essential.That’s why I’m pleased to recommend Pharmacology: A 2-in-1 Reference for Nurses.Whether you need a minor memory booster or a com- plete refresher course,this book has it. Ingenious format The first thing you’ll notice about Pharmacology: A 2-in-1 Reference for Nursesis its ingenious two-column format.The inner two-thirds ofeach page contains a full nar- rative on drugs and their classes.The outer third ofeach page contains abbreviated, bulleted information that’s perfect for quick scanning.The full effect ofthis two-part design is that you can skip the information you already know,quickly review any- thing you want to clarify or update,and easily go in-depth whenever you choose—all in the same book,often on the same page. For example,ifyou’re pressed for time or you just want a quick refresher,skim the narrow column on the outside edge ofeach page.Here you’ll find all the most perti- nent points ofeach drug class and many individual drugs in convenient bulleted form.Ifyou want a more extensive review,simply shift your eyes over to the main column,where you’ll find a more expanded version ofthe same topic.The informa- tion is still concise and clear,just more detailed. Practical approach And here’s an important distinction.It isn’t just the flexible format that sets this book apart.It’s the content itself. For one thing,it’s grouped in the most practical way possible:by therapeutic use. You’ll find individual chapters on the most important drug groups,such as cardiovas- cular drugs,respiratory drugs,GI drugs,anti-infectives,antineoplastics,neurologic drugs,and much more.You’ll also find full chapters on drug classes ofincreasing scope and importance,such as immunomodulating drugs,psychotropic drugs,and endocrine drugs. For another thing,drug information is organized to follow a consistent,practical order:pharmacokinetics,pharmacodynamics,pharmacotherapeutics,interactions, adverse reactions,and nursing considerations. You’ll also find chapters on equally practical matters,such as essential dosage cal- culations,step-by-step drug administration techniques,best drug-error sidesteps,and the must-know pharmacologic fundamentals. ix 3203 FM.QXD 8/29/08 12:27 PM Page x x FOREWORD A final practical aspect ofthis flexible book is its special logo features.These tar- geted short pieces call your attention to selected major topics and offer concise,scan- and-go information.Look for these helpful boxes and illustrations throughout the text: ✦ Eye on drug action:Illustrations to help you visualize—and remember—the often complicated ways drugs work. ✦ Lifespan:Considerations to carefully care for pregnant,breast-feeding,pediatric, or geriatric patients. ✦ Warning:Highlighted information about dangerous,hazardous,or life-threatening developments and how to avoid them. ✦ Anatomy & physiology:Illustrations ofbody systems and functions to refresh your memory. ✦ Patient teaching:Important points to tell patients about a drug class or a particular drug. ✦ Clinical alert:A colored logo to draw your attention to vitally important informa- tion in the main body ofthe text. Every nurse knows that a sound understanding ofpharmacology goes hand in hand with safe drug administration.Pharmacology: A 2-in-1 Reference for Nursesgives you as quick a review as you want and as complete a reference as you need,all in a surprisingly practical package.I recommend it enthusiastically.
