What is the term defined as a system of ideas that explains a given phenomenon?

The term that is defined as a system of ideas that explains a given phenomenon is a theory. In the context of nursing and other scientific disciplines, a theory serves as a framework for understanding and interpreting various aspects of human health and behavior. It goes beyond mere observation, providing a cohesive explanation that integrates various concepts and ideas into a comprehensive understanding.

Theories in nursing guide practice by offering clear insights into the relationships between different variables and can help predict outcomes based on certain conditions. They are essential for developing evidence-based practices and informing research.

In contrast, concepts refer to individual elements or ideas that contribute to a broader theoretical framework. Guidelines are typically more practical instructions or recommendations for action, while a hypothesis is a specific prediction that can be tested through research. Therefore, while all of these terms are related to the process of understanding and interpreting phenomena, theory specifically encapsulates a structured system that explains and connects various concepts into a coherent whole.
