Which term is a broad, testable statement used to explain relationships in nursing science?

• A. Theory
• B. Hypothesis
• C. Evidence Based Practice
• D. Model

Answer: (A)

Theory in nursing provides broad statements that explain how different phenomena are related and how changing one aspect might influence another. It offers a framework with concepts and propositions that can be tested through research, yielding explanations and predictions about patient care, outcomes, and health behaviors. This broad, testable nature lets theories guide both inquiry and practice, linking limited observations to a cohesive understanding of nursing phenomena across contexts. A hypothesis is a specific, testable prediction derived from a theory that is evaluated in a particular study. Evidence-Based Practice is about applying the best available evidence, clinical expertise, and patient values to care decisions, not about describing relationships in a broad theoretical sense. A model provides a simplified representation of relationships to help people visualize how components fit together, but it isn’t necessarily as broad or as testable as a theory.
