The document discusses the metaparadigm of nursing theories, which consists of four main concepts - person, health, environment, and nursing - that provide a framework for the nursing discipline. The person concept refers to individuals as unique with their own values and beliefs. Health encompasses a patient's quality of well-being as well as their access to healthcare. Environment includes internal and external factors surrounding the patient. Nursing is the application of a nurse's knowledge and skills when caring for patients.
