Lehne's Pharmacotherapeutics for Advanced Practice Nurses and Physician Assistants, 2nd Edition builds on the same foundation of clearly explained, up-to-date, and clinically current content as the trusted Lehne undergraduate text, while focusing on the information that advanced practice nurses and Physician Assistants specifically need for safe and effective prescribing. Three introductory chapters provide foundational content for new prescribers in the areas of prescriptive authority, rational drug selection, prescription writing, and promoting positive outcomes of drug therapy. Core drug chapters are focused on the drugs that prescribers will most commonly see in clinical practice. Introductory chapters tailored to the specific needs of prescribers cover topics such as prescriptive authority, rational drug selection and prescription writing, and promoting positive outcomes of drug therapy. Carefully focused pharmacotherapeutic content reflects the drugs most commonly seen and used by prescribers, with emphasis not on the first drug discovered or developed in each class but on the agents most often used today. Primary care drugs are addressed first in each chapter as appropriate, followed by acute care drugs. UNIQUE! Prescriber-focused pedagogical aids further reinforce the most important information for prescribers - like Black Box Warnings that alert readers to special warnings and precautions related to particular drugs. Integrated coverage of Canadian trade names appears throughout the text and is highlighted with a familiar maple-leaf icon. Integrated coverage of interprofessional collaboration addresses the growing global interest in interprofessional collaboration and incorporates opportunities for interprofessional collaborative practice throughout.
