Pharmacology for nurses: a pathophysiologic approach
When students are asked which subject in their nursing program is the most challenging, pharmacology always
appears near the top of the list. The study of pharmacology demands that students apply knowledge from a wide
variety of the natural and applied sciences. To successfully predict drug action requires a thorough knowledge of anatomy, physiology, chemistry, and pathology as well as the social sciences of psychology and sociology. Lack of proper application of pharmacology can result in immediate and direct harm to the client; thus, the stakes in learning the subject are high.
Pharmacology cannot be made easy, but it can be made understandable, if the proper connections are made to knowledge learned in these other disciplines. The vast majority of drugs in clinical practice are prescribed for specific diseases, yet many pharmacology textbooks fail to recognize the complex interrelationships between pharmacology and pathophysiology. When drugs are learned in isolation from their associated diseases or conditions, students have difficulty connecting pharmacotherapy to therapeutic goals and client wellness. The pathophysiology approach of this textbook gives the student a clearer picture of the importance of pharmacology
to disease, and ultimately to client care. The approach and rationale of this textbook focus on a holistic
perspective to client care, which clearly shows the benefits and limitations of pharmacotherapy in curing or preventing illness. Although difficult and challenging, the study of pharmacology is truly a fascinating, lifelong journey.
