Nursing theories address the concept of holistic care by emphasizing the importance of treating the whole person, including physical, emotional, social, and spiritual aspects. Theories like Jean Watson’s Theory of Human Caring highlight the significance of building caring relationships and understanding patients’ emotional and psychological needs. Similarly, Orem’s Self-Care Deficit Theory encourages nurses to consider patients’ abilities and preferences in managing their health, fostering a more comprehensive approach to care. By integrating holistic perspectives into their practice, nurses are better equipped to recognize the multifaceted nature of health and illness, leading to more effective interventions and improved patient outcomes. These theories promote the idea that optimal care involves not only addressing medical issues but also supporting patients’ overall well-being.
