For courses in undergraduate/graduate-level nursing theory. Nursing Theories: The Base for Professional Nursing Practice, Sixth Edition, is designed to help nurses apply concepts and theories to practice. This useful resource considers the ideas of well-known nursing theorists and relates the work of each to the clinical nursing practice. Chapters are organized to relate the theorist's work to the nursing metaparadigm, clinical nursing practice, characteristics of a theory, and strengths and limitations of the theory.
