Virginia Henderson's Need Theory defines the unique role of nursing as assisting individuals who are unable to care for themselves to meet their basic human needs and regain independence. The theory outlines 14 components of basic human needs that nursing aims to help patients satisfy, including physiological needs like breathing, eating, and eliminating, as well as psychological, social, and spiritual needs. Henderson believed nurses should work to temporarily perform any functions patients are unable to do for themselves due to illness or injury and help patients recover independence as quickly as possible. While influential, the theory lacks clarity in some areas like prioritization of needs and application to patients requiring long-term care. Overall, it provides a foundation for understanding nursing's focus on meeting patient needs.
