Learn, understand, and master pathophysiology The Biologic Basis for Disease in Adults and Children, 9th Edition, this study guide offers practical activities and detailed case studies to help you review and remember basic pathophysiology and make the connections between theory and practice. Interactive questions provide you with a working knowledge of disease etiology and disease processes - giving you practice applying what you've learned to clinical practice. Best of all, the answers are in the back of the book so that you can check your understanding as you go Thoroughly revised and updated information mirrors content from the 9th edition of the McCance & Huether's Pathophysiology textbook.
NEW! Thoroughly revised and updated information mirrors content from the 9th edition of the McCance & Huether's Pathophysiology textbook. NEW! Over 40 detailed case scenarios provide real-world examples of how pathophysiology is used in the clinical setting, helping you integrate knowledge, develop clinical judgment, and apply theory to practice.

Respond to clinical situations
Place yourself in these situations and write your responses in the spaces provided.
