What distinguishes a middle-range theory from a grand theory of nursing?
A.
Middle-range theories have a large number of variables, while grand theories have only a few.
B.
Grand theories are socially significant, while middle-range theories have theoretical significance.
C.
Middle-range theories form a theoretical framework for evidence-based practice (EBP) research projects.
D.
There are fewer middle-range theories than there are grand theories.
Answer: C. Middle-range theories form a theoretical framework for evidence-based practice (EBP) research projects.
Explanation:
Middle-range theories are more specific and focused than grand theories, making them more applicable to specific aspects of nursing practice. They provide a theoretical framework that can guide evidence-based practice (EBP) research projects by focusing on concrete concepts and relationships that can be empirically tested. Grand theories, on the other hand, are broader, more abstract, and often provide a general framework for understanding nursing as a whole rather than specific, actionable guidance for practice or research.
