How does Sister Callista Roy suggest nurses promote system stability?

Sister Callista Roy emphasizes the importance of promoting system stability through her Adaptation Model, which identifies the need to address health care through various levels of prevention. Utilizing the three levels of prevention—primary, secondary, and tertiary—nurses can effectively maintain and enhance the health status and adaptation of individuals within their environments.

By focusing on primary prevention, nurses work to prevent health issues before they develop, promoting wellbeing and reducing the incidence of disease. Secondary prevention involves early detection and intervention, allowing for prompt treatment and management of health conditions. Tertiary prevention aims to manage and rehabilitate patients with existing diseases to prevent further complications. This comprehensive approach addresses the individual holistically and sustains their ability to adapt to changing health needs, thereby promoting stability within the system.

The other choices do not encapsulate the holistic and structured approach that is central to Roy's model. Providing only tertiary prevention would limit the care strategy to managing existing conditions rather than preventing them. Focusing solely on psychological therapies may neglect the physiological and social dimensions of health. Creating new health models, while potentially valuable, does not directly relate to the structured application of prevention strategies necessary for promoting system stability as per Roy's framework.
