Which of the following concepts is NOT one of the four major concepts of nursing?

The correct choice indicates that "Patient care technology" is not one of the four major concepts of nursing. In nursing theory, the foundational concepts typically include Person, Environment, Health, and Nursing. These four elements help define the scope of nursing practice and form the basis for nursing knowledge and philosophy.

The "Person" refers to individuals, families, or communities receiving care. "Environment" encompasses both internal and external factors that influence health and well-being. "Nursing" itself addresses the actions, roles, and responsibilities of nursing professionals in delivering care.

While patient care technology is intensely relevant to modern nursing practice—shaping how care is delivered, enhancing patient monitoring, and improving outcomes—it does not constitute one of the core theoretical foundations defining the essence or discipline of nursing. Instead, it is a tool or resource that supports nursing practice rather than a conceptual framework within the discipline. This delineation helps clarify the theoretical underpinnings of nursing as a holistic and patient-centered profession.
