Classification of nursing theories by scope differentiates them (Select all the apply)

When nursing theories are classified by scope, the organizing principles are their level of abstraction and complexity. The traditional framework groups theories into four hierarchical levels — metatheory (concerned with the philosophy and methodology of theory development), grand theories (broad conceptual frameworks), middle-range theories (more specific and testable propositions), and practice theories (also called situation-specific theories, directly guiding clinical care). This four-level taxonomy is correct. Scope classification is also inherently tied to complexity and degree of abstraction: metatheories are highly abstract, while practice theories are narrow and concrete. These two options work together as the foundation of scope-based classification. The option about borrowed versus unique theories describes a different classification scheme based on the origin of knowledge, not scope. Education levels of practicing nurses is irrelevant to theory classification. Classifying by the knowledge stage of development refers to historical or epistemological frameworks, not scope. Students sometimes confuse scope classification with other taxonomies such as philosophical origin or historical era, so recognizing that scope specifically addresses breadth, abstraction, and complexity is the key insight here.
