There are a couple chapters of the actually textbook I did not read and with my instructor's powerpoints and this study guide, I was able to still make all As on the exam.I didn't always use and I know some of classmates never used it. If like workbooks then it's great to have. If you're not a workbook person then you should probably skip it.It's good I guess to see the style questions, but I feel like if you're going to rent a book it shouldn't have this much writing in it. Very frustrating.It is current and comprehensive. Good text.I suggest getting the physical book. The 13-digit and 10-digit formats both work. Please try again.

Yet, despite its importance, many students—and even some teachers—are often uncomfortable with the subject. Why? Because traditional texts have stressed memorizing rather than understanding. In this text, the guiding principle is to establish a basic understanding of drugs, after which secondary details can be learned as needed. This text has two major objectives: to help you, the nursing student, establish a knowledge base in the basic science of drugs, and to show you how that knowledge can be applied in clinical practice. The methods by which these goals are achieved are described below.When attempting to study from such a list, you are likely to learn many drug names and little else; the important concept of similarity among family members is easily lost. In this text, the family prototype—aspirin—is discussed first and in depth. After this, the small ways in which individual NSAIDs differ from aspirin are pointed out. Not only is this approach more efficient than the traditional approach, it is also more effective, in that similarities among family members are emphasized. LARGE PRINT AND SMALL PRINT: A WAY TO FOCUS ON ESSENTIALS LAYING FOUNDATIONS IN BASIC PRINCIPLES Pharmacology is exceptionally rich in detail. There are many drug families, each with multiple members and each member with its own catalogue of indications, contraindications, adverse effects, and drug interactions. This abundance of detail confronts teachers with the difficult question of what to teach, and students with the equally difficult question of what to study.BARSUGO.COM/ckfinder/userfiles/files/construction-equipment-manuals-online.pdf Attempting to answer these questions can frustrate teachers and students alike. Even worse, in the presence of myriad details, basic concepts can be obscured. To help you focus on essentials, there are two sizes of type. Large type is intended to say, “On your first exposure to this topic, this is the core of information you should learn.” Small type is intended to say, “Here is additional information that you may want to learn after mastering the material in large type.” As a rule, we reserve large print for prototypes, basic principles of pharmacology, and reviews of physiology and pathophysiology. We use small print for secondary information about the prototypes and for discussion of drugs that are not prototypes. This technique allows the book to contain a large body of detail without having that detail cloud the big picture. Furthermore, because the technique highlights essentials, it minimizes questions about what to teach and what to study. The use of large and small print is especially valuable for discussing adverse effects and drug interactions. Most drugs are associated with many adverse effects and interactions. As a rule, however, only a few of these are noteworthy. In traditional texts, practically all adverse effects and interactions are presented, creating long and tedious lists. In this text, we use large print to highlight the few adverse effects and interactions that are especially characteristic; the rest are noted briefly in small print. Rather than overwhelming you with long and forbidding lists, this text delineates a moderate body of information that’s truly important, and thereby facilitates comprehension. To understand drugs, you need a solid foundation in basic pharmacologic principles. To help you establish that foundation, the book has major chapters on the following topics: basic principles that apply to all drugs (Chapters 4 through 8), basic principles of drug therapy across the life span (Chapters 9 through 11), basic principles of neuropharmacology (Chapter 12), basic principles of antimicrobial therapy (Chapter 83), and basic principles of cancer chemotherapy (Chapter 101). REVIEWING PHYSIOLOGY AND PATHOPHYSIOLOGY To understand the actions of a drug, it is useful to understand the biologic systems that the drug influences. Accordingly, for all major drug families, relevant physiology and pathophysiology are reviewed. In almost all cases, these reviews are presented at the beginning of each chapter, rather than in a systems review at the beginning of a unit. This juxtaposition of pharmacology, physiology, and pathophysiology is designed to help you understand how these topics interrelate. TEACHING THROUGH PROTOTYPES Within each drug family, we can usually identify a prototype—that is, a drug that embodies characteristics shared by all members of the group. Because other family members are similar to the prototype, to know the prototype is to know the basic properties of all family members. The benefits of teaching through prototypes can be appreciated with an example. Traditionally, information on viii PREFACE current research. Canadian trade names have been updated and continue to be identified by a maple-leaf icon. USING CLINICAL REALITY TO PRIORITIZE CONTENT This book contains two broad categories of information: pharmacology (ie, basic science about drugs) and therapeutics (ie, clinical use of drugs). To ensure that content is clinically relevant, we use evidence-based treatment guidelines as a basis for deciding what to stress and what to play down. Unfortunately, clinical practice is a moving target: When effective new drugs are introduced, and when clinical trials reveal new benefits or new risks of older drugs, the guidelines change—and so we have to work hard to keep this book current. Despite our best efforts, the book and clinical reality may not always agree: Some treatments discussed here will be considered inappropriate before the 10th edition comes out. Furthermore, in areas where controversy exists, the treatments discussed here may be considered inappropriate by some clinicians right now. The principal reason for asking you to learn pharmacology is to enhance your ability to provide patient care and education. To show you how pharmacologic knowledge can be applied to nursing practice, nursing implications are integrated into the body of each chapter. That is, as specific drugs and drug families are discussed, the nursing implications inherent in the pharmacologic information are noted side-byside with the basic science. To facilitate access to nursing content, nursing implications are also summarized at the end of most chapters. These summaries serve to reinforce the information presented in the chapter body. In chapters that are especially brief or that address drugs that are infrequently used, summaries of nursing implications have been omitted. However, even in these chapters, nursing implications are incorporated into the main chapter text. WAYS TO USE THIS TEXTBOOK Thanks to its focus on essentials, this text is especially well suited to serve as the primary text for a course dedicated specifically to pharmacology. In addition, the book’s focused approach makes it a valuable resource for pharmacologic instruction within an integrated curriculum and for selfdirected learning by students, teachers, and practitioners. How is this focus achieved. Four primary techniques are employed: (1) teaching through prototypes, (2) using standard print for essential information and small print for secondary information, (3) limiting discussion of adverse effects and drug interactions to information that matters most, and (4) using evidence-based clinical guidelines to determine what content to stress. To reinforce the relationship between pharmacologic knowledge and nursing practice, nursing implications are integrated into each chapter. Also, to provide rapid access to nursing content, nursing implications are summarized at the end of most chapters, using a nursing process format. In addition, key points are listed at the end of each chapter. As in previous editions, the ninth edition emphasizes conceptual material—reducing rote memorization, promoting comprehension, and increasing reader friendliness. Pharmacology can be an unpopular subject due to the vast and rapidly changing area of content. Often, nursing students feel that pharmacology is one of the most difficult classes to master. We hope that this book makes the subject of pharmacology easier and more enjoyable for you to understand by allowing you to focus on the most important, umbrella concepts of pharmacology as they relate to nursing care and the safety of patients.In addition, the popular Special Interest Topics of past editions have been thoroughly revised to allow for the most ix PREFACE Finally, we would like to express our gratitude to Richard A. Lehne for his dedication to this book for eight editions. We are honored to be able to continue his work.

Jacqueline Rosenjack Burchum Laura D. Rosenthal x CHAPTER 1. Orientation to Pharmacology pharmacology includes knowledge of the history, sources, and uses of drugs as well as knowledge of drug absorption, distribution, metabolism, and excretion. Because pharmacology encompasses such a broad spectrum of information, it would be impossible to address the entire scope of pharmacology in this text. Consequently, we limit consideration to information that is clinically relevant. Clinical Pharmacology.? Clinical pharmacology is defined as the study of drugs in humans. This discipline includes the study of drugs in patients as well as in healthy volunteers (during new drug development). Because clinical pharmacology encompasses all aspects of the interaction between drugs and people, and since our primary interest is the use of drugs to treat patients, clinical pharmacology includes some information that is outside the scope of this text. Therapeutics.? Therapeutics, also known as pharmacotherapeutics, is defined as the use of drugs to diagnose, prevent, or treat disease or to prevent pregnancy. Alternatively, therapeutics can be defined simply as the medical use of drugs. In this text, therapeutics is our principal concern. Accordingly, much of our discussion focuses on the basic science that underlies the clinical use of drugs. This information is intended to help you understand how drugs produce their effects—both therapeutic and adverse; the reasons for giving a particular drug to a particular patient; and the rationale underlying selection of dosage, route, and schedule of administration. This information will also help you understand the strategies employed to promote beneficial drug effects and to minimize undesired effects. Armed with this knowledge, you will be well prepared to provide drug-related patient care and education. In addition, by making drugs less mysterious, this knowledge should make working with drugs more comfortable, and perhaps even more satisfying. Happily, now you have one: You’ve spent most of your life in school so you could study pharmacology. There’s good reason you haven’t approached pharmacology before now. Pharmacology is a science that draws on information from multiple disciplines, among them anatomy, physiology, chemistry, microbiology, and psychology. Consequently, before you could study pharmacology, you had to become familiar with these other sciences. Now that you’ve established the requisite knowledge base, you’re finally ready to learn about drugs. FOUR BASIC TERMS At this point, I’d like to define four basic terms: drug, pharmacology, clinical pharmacology, and therapeutics. As we consider these definitions, I will indicate the kinds of information that we will and will not discuss in this text. Drug.? A drug is defined as any chemical that can affect living processes. By this definition, virtually all chemicals can be considered drugs, since, when exposure is sufficiently high, all chemicals will have some effect on life. Clearly, it is beyond the scope of this text to address all compounds that fit the definition of a drug. Accordingly, rather than discussing all drugs, we will focus primarily on drugs that have therapeutic applications. Pharmacology.? Pharmacology can be defined as the study of drugs and their interactions with living systems. Under this definition, pharmacology encompasses the study of the physical and chemical properties of drugs as well as their biochemical and physiologic effects. In addition, PROPERTIES OF AN IDEAL DRUG If we were developing a new drug, we would want it to be the best drug possible. To approach perfection, our drug should have certain properties, such as effectiveness and safety. In the discussion below, we consider these two characteristics as well as others that an ideal drug might have.
