What key concept does Betty Neumann's Systems Model center around?

Betty Neumann's Systems Model primarily focuses on the relationship between a client and stress, making this the correct answer. In her model, Neumann emphasizes that a person's health and well-being are influenced by various stressors from the internal and external environments. The model represents clients as open systems that interact with these stressors, and the objective is to maintain stability and promote optimal health.

This understanding of stress and its impact on clients is crucial in nursing and coaching practice, as it acknowledges that health is not merely the absence of disease but a dynamic interplay of stressors and coping mechanisms. Neumann's model encourages nurses and coaches to assess and manage these stressors through a holistic approach, providing care that considers the full spectrum of factors affecting a client’s health.

While the other options present relevant concepts, they do not encapsulate the primary focus of Neumann's model. The role of energy resources in health or the promotion of primary prevention are important aspects of health care but are not the central theme of her systems approach. Similarly, the concept of lines of resistance pertains to how systems respond to stressors but is more of a supporting element rather than the main concept around which Neumann's model revolves. Therefore, understanding the client-stress relationship is
