Final answer:
The term that refers to nurses using a particular nursing theory to guide their practice in assessing, diagnosing, and evaluating care is 'nursing theoretical framework' or 'theory-based nursing practice.' This method can incorporate critical theories of health, cultural systems model, ethnomedicine, and epigenetics to improve the health care system and client outcomes.
Step-by-step explanation:
The term that describes when nurses intentionally structure their practice around a particular nursing theory and use it to guide them as they assess, plan, diagnose, intervene, and evaluate nursing care is often referred to as nursing theoretical framework or theory-based nursing practice. This approach encompasses various concepts including critical theories of health, which serve as an applied method aimed at improving health care systems and policies. Nursing practice can also incorporate cultural concepts of distress and cultural systems model, which acknowledges how cultural beliefs and health care systems interact and influence health care practices and patient outcomes.
These frameworks also involve an understanding of ethnomedicine and epigenetics, as nurses take into account the cultural knowledge of health and illness as well as the changes in gene expression that can arise during a person's lifetime. By drawing from these theories and employing them in clinical practice, nurses can deliver more culturally competent and personalized care, ultimately engaging in a form of medical anthropology in action. This is an essential aspect of providing holistic and knowledgeable patient care that meets a variety of health needs and outcomes.
