BSN 310 Theoretical Foundations of Nursing explores the theories that guide nursing practice and research. This course also examines the extent to which practice influences the development of theory, the definitions of theories, and the different types of theories. In particular, students learn how grand nursing theories have evolved and the importance of midrange and practice theories for guiding patient care. Emphasis is also given on the relationships between nursing theories and nursing models, the criteria used for choosing an appropriate theory to underpin nursing practice, and how to test theories to ascertain their value for nursing practice and research.
