This theory is defined as the interdependence of environments in and around us. In nursing this means that we must understand that all parts of a system are connected, that a change in one part will have an affect on another.

• A. Systems Theory
• B. Developmental Theory
• C. Chaos Theory
• D. Information Theory

Answer: (A)

Understanding that environments are interdependent and that a change in one part affects others is the essence of Systems Theory. In nursing, this means seeing patient care as a network where the patient, family, care team, workplace, policies, and even the social environment all interact, so shifting one element can ripple through the rest and change outcomes, safety, and efficiency. This perspective supports holistic, coordinated care and the use of feedback loops to guide assessment and intervention. Other theories don’t capture this broad interconnection: Developmental Theory focuses on growth stages over time, Chaos Theory on nonlinear, unpredictable dynamics, and Information Theory on how messages are encoded and transmitted. So the described concept aligns with Systems Theory.
