This is a Pageburst digital textbook; With a consistent focus on application throughout, Nursing Theory covers the development of nursing theory; the application of different nursing theories, models and philosophies; and the expansion of these practices with a look toward the future. Nursing Theory provides the opportunity for students who have learned the background of nursing theory using the companion title, Nursing Theorists and Their Work, to apply what they have learned to actual nursing practice through various patient scenarios. Features two case history boxes in each chapter: one with a patient named Debbie, whom the reader can follow throughout the book, and another with a patient from a unique cultural or religious perspective. These case histories provide realistic examples of how to apply theory to the clinical side of nursing, as well as show common exceptions to the standard care plans. Includes a unique chapter on Philosophies, Models, and Theories: Moral Obligations, which explores the moral and ethical meaning of nursing practice and specific nursing duties. Logically organized for easier understanding: Conceptualization (history of nursing theory), Application (how to apply theory to practice), and Expansion (how to expand theory-based practice) Gives practical examples of how to apply the theories taught in the companion volume, Nursing Theorists and Their Work. Updated nursing application examples feature realistic scenarios that promote evidence-based practice. Scenarios have been updated using references to current literature and evidence-based clinical research. New information on the benefits and cautions associated with evidence-based practice, including a new discussion of "praxis," a dynamic process where theory and practice come together. Updated critical thinking exercises reflect the role of the nursing professional and advanced nursing practice, encouraging a higher level of thinking regarding the integration of theory and practice.
