Revised in its Ninth Edition, this popular text reference continues to set the standard for learning key elements of nursing diagnosis, its role in the nursing process, and applications to clinical practice. The emphasis is on diagnosis, practical application, assessment, intervention and rationale (including summaries), and outcome criteria. The features include the Author's Notes, plus guidelines and keys that focus on assessment data, concepts, differentiating nursing diagnoses, developing care plans, and controversies surrounding diagnosis and critical care pathways. It also includes a special section on 'Collaborative Problems' and 'Diagnosis Clusters'. An overall change in design including the addition of a second color makes the text easier to read and enhances its appearance.
