Nursing theory is a framework that helps nurses understand and explain their practice. It provides a structured way to think about patient care, guiding nurses in their decision-making and actions. By using these theories, nurses can improve patient outcomes and enhance the quality of care they provide. There are various types of nursing theories, such as Jean Watson's Theory of Human Caring and Dorothea Orem's Self-Care Theory. Each theory offers unique insights into the nursing process, emphasizing different aspects of patient care, such as emotional support or the importance of self-care. These theories are essential for developing effective nursing practices.
