Final answer:
Nursing theories range from concrete, specifically focused on certain populations or practices, to very abstract, similar to sociological theories, and the statement is true.
Step-by-step explanation:
The statement that nursing theories can be categorized by the degree of abstraction, ranging from concrete, population-specific practice theory, through minimalist range theories, to maximum abstract theories, is True.
Similar to sociological theories, nursing theories help explain and guide the practice within the discipline.
They vary in scope and scale, with micro-level theories addressing specific patient or population scenarios, while macro-level, or grand theories, establish a broader understanding of healthcare and patient well-being.
Nursing theorists and researchers develop, test, and refine these theories to ensure they are in keeping with current practice and empirical evidence.
