"An Introduction to the Theoretical Basis of Nursing" explores the foundational concepts that guide nursing practice. It emphasizes the importance of theories in understanding patient care, promoting health, and improving outcomes. Key nursing theories, such as those proposed by Florence Nightingale and Jean Watson, provide frameworks for nurses to assess and address the needs of patients holistically. Theoretical frameworks in nursing help to define roles, responsibilities, and the relationship between nurses and patients. By applying these theories, nurses can enhance their critical thinking and decision-making skills, ultimately leading to more effective and compassionate care in various healthcare settings.
