This popular core nursing pharmacology textbook provides unique coverage of nursing interventions for drug therapy with related rationales. Highly praised for its organized and readable presentation, the text explains the "why" behind each nursing action and emphasizes how drugs work differently in different patients. New to the Ninth Edition is an Evidence-Based Nursing feature that builds on the previous edition's Research Briefs and highlights the nursing implications of current research. Chapter openers now include key terms with definitions. Other highlights include a comprehensive glossary, a revised art program, and thoroughly revised end-of-chapter NCLEX-style questions.
