Nursing models are frameworks that guide nursing practice and education. They help nurses understand patient care by providing structured approaches to assess, plan, implement, and evaluate care. Common nursing models include the Orem Self-Care Model, which emphasizes patient independence, and the Rogers' Science of Unitary Human Beings, which focuses on the holistic nature of individuals. These models serve as tools for nurses to improve patient outcomes and enhance communication within healthcare teams. By applying these frameworks, nurses can better address the physical, emotional, and social needs of patients, ensuring comprehensive care that promotes overall well-being.
