• Each nursing model developed by these theorists shaped nursing knowledge, nursing education, and clinical practice worldwide.

C. Overview of the Nursing Metaparadigm

• The nursing metaparadigm includes four central concepts:
  • Person – the recipient of nursing care.
  • Health – overall well-being and quality of life.
  • Environment – all external conditions affecting health.
  • Nursing – the actions and responsibilities of the nursing profession.
• Theories guide how these elements interact in nursing practice and the model of nursing frameworks.
• Theories may adapt over time to reflect evolving nursing problems and healthcare needs.

D. Types of Nursing Theories

• Grand Nursing Theories – Broad frameworks that explain the overall nature of nursing practice (e.g., Orem’s Self-Care Deficit Theory).
• Middle-Range Nursing Theories – More focused, practical applications for nursing intervention (e.g., Kolcaba’s Theory of Comfort).
• Middle-range theories address specific areas of nursing care without being overly abstract.
• Specific Nursing Models – Target unique clinical or cultural contexts, such as Transcultural Nursing.
• These theories provide a roadmap for nursing students, educators, and practitioners to integrate nursing knowledge into patient care effectively.

III. Grand Nursing Theories
