Models and theories in nursing research are understood to be:

Models and theories in nursing research play a crucial role in the development of the discipline by providing a framework for understanding phenomena, guiding research, and generating hypotheses. They offer a structured way to conceptualize problems, which can lead to new lines of inquiry and inform practice by articulating how and why nursing interventions work.

The usefulness of models and theories in generating hypotheses is particularly significant because it lays the groundwork for empirical research. By applying theoretical frameworks, researchers can identify variables of interest, predict relationships, and formulate testable statements. This ability to generate hypotheses is fundamental in advancing knowledge and improving patient outcomes within nursing.

In contrast, some choices suggest limitations that do not accurately reflect the broader role of models and theories. For instance, stating that they are exclusive to qualitative research overlooks their applicability in quantitative studies as well. Similarly, claiming they are only relevant to community health research disregards their significance across various areas of nursing practice. Lastly, the idea that they are irrelevant to nursing practice underscores a misunderstanding of how theoretical frameworks inform clinical decision-making and advance the discipline.

In summary, the assertion that models and theories are useful in generating hypotheses accurately captures their integral function in nursing research.
