This document outlines the requirements for an assignment on the importance of nursing theory. Students must select one nursing theory, describe its key concepts, and discuss how it addresses the four main concepts in nursing (person, health, environment, nursing). They then apply the theory to one of five nursing practice areas and provide two examples. The paper must follow APA style, cite at least four scholarly sources, pass Turnitin, and be 5-7 pages long, excluding references.
