Written by and for nurse practitioners, and also well suited for physician's assistant students, this practical textbook focuses on what primary care providers need to kw in order practice safe and effective drug therapy. With an overall emphasis on patient teaching and health promotion, Edmunds & Mayhew teaches students and practitioners how to provide effective patient teaching about medications and how to promote adherence to prescribed drug regimens. Drug coverage focuses on key drugs - those most commonly used and most representative of each major drug class - with particular emphasis on the top 100 most commonly prescribed drugs. The book also features integrated coverage of nationally accepted clinical and evidence-based practice guidelines. The new 4th edition features a completely new full-color design and illustration program; coverage of new drugs, new drug classes, and new therapeutic drug uses; updated coverage of the latest national clinical and evidence-based treatment guidelines; newly integrated and highlighted coverage of drug-herb interactions; an expanded emphasis on safety and evidence-based practice, consistent with the QSEN initiative, retooled Safety Alert! and Clinical Practice Alert! highlights; and expanded and an enhanced ancillary package emphasizing graduate-level QSEN KSAs and new pharmacology-focused ArchieMD animations.
