Which concept relates to the interaction of individuals within their surroundings?

The concept that relates to the interaction of individuals within their surroundings is the environment. In nursing theories, the environment encompasses not only the physical surroundings but also the social, cultural, and economic factors that impact health. This understanding aligns with the holistic approach of nursing, which emphasizes the importance of considering the broader context of a patient's life.

The environment influences various aspects of health, such as access to healthcare, lifestyle choices, and social support systems. For instance, a person's living conditions, community resources, and even the air quality in their environment can significantly affect their overall well-being. By focusing on the environment, nurses can better assess health risks and determine how external factors may be contributing to a patient's health status, enabling them to develop more comprehensive care plans.

In contrast, health outcomes focus on the results of healthcare interventions, technology pertains to the tools and resources used in healthcare practice, and education addresses the knowledge and skills imparted to both patients and healthcare providers. While all these elements have their roles within the healthcare system, the environment is specifically about the interaction between individuals and their surroundings, making it the correct choice for this question.
