Theories and conceptual models from nursing and related fields for use in advanced nursing practice

Sample Answer

The integration of robust theoretical frameworks and conceptual models is fundamental to advanced nursing practice, providing a structured approach to complex patient care, research, and policy development. Advanced Practice Registered Nurses (APRNs) leverage these intellectual constructs to guide assessment, diagnosis, intervention, and evaluation, ensuring evidence-based and holistic care. This evaluation will explore the utility of select theories and models from nursing and related fields, highlighting their applicability in the advanced nursing role.
