What type of theory is primarily used for describing and labeling phenomena in nursing?

The correct answer is Factor Isolating Theory. This type of theory is essential in nursing as it focuses on defining and categorizing specific phenomena within the nursing practice. Factor isolating theories help nurses articulate and label the various elements they encounter in patient care, such as symptoms, behaviors, and responses. By providing a framework to identify and describe these phenomena, this theory aids in developing a common language among nurses and enhances the understanding of nursing care tasks.

For instance, a nurse might use a factor isolating theory to classify different types of pain that patients report. This process not only improves communication among healthcare professionals but also contributes to the development of nursing diagnoses and interventions. By clearly defining phenomena, nurses can create more effective care plans that are based on identified patient needs.

The other types of theories, while also important in nursing, serve different purposes. Explanatory theories aim to clarify relationships between concepts and provide insight into why phenomena occur, prescriptive theories focus on suggesting specific actions for nursing practice, and practice-level theories provide guidance on the application of nursing knowledge in real-world settings. These theories do not primarily focus on the description and labeling of phenomena, which is the critical function of factor isolating theory.
