Which theories are less abstract and more focused, suitable for guiding practice?

• A. Midrange theories.
• B. Grand theories.
• C. Conceptual models.
• D. Evidence-based practice.

Answer: (A)

The main idea being tested is choosing theories that are practical enough to guide actual nursing practice. Midrange theories sit between broad, abstract grand theories and the day-to-day realities of care. They focus on a specific, clearly defined phenomenon and lay out testable relationships between concepts, making it possible to guide assessment, interventions, and evaluation in real clinical settings. Because they are narrower in scope, they can be studied, refined, and translated into concrete practice guides or protocols, providing actionable steps that nurses can apply with patients.

In contrast, grand theories are broad and highly abstract, offering wide-ranging explanations that are difficult to translate into specific actions at the bedside. Conceptual models provide frameworks for thinking about how concepts relate but often lack the precise, testable propositions that midrange theories offer. Evidence-based practice is a approach to decision-making that integrates research, clinical expertise, and patient values rather than a theoretical explanation of phenomena, so it functions differently from a theory aimed at guiding practice.
