The four nursing concepts are the person, environment, health, and nursing. These concepts are also known as the metaparadigm. Person, who is the patient, is also referred to as the client, individual, family, community, or group (Whitney 2018). The person is anyone in the nurses care. The environment is both internal and external. Internal is anything that occurs within the recipient personal space or self, such as an emotional or psychosocial issue. External is what affects the persons on an outward level such as family, community etc. Health refers to the person state of being, which can be a state of wellness or illness. Nursing is the action of the nurse, the ability to look at the person holistically and apply professional knowledge in caring. In Jean Watson’s theory, the person is a unity of mind, body, and spirit (Wayne, 2021). In caring for a patient that reports being depressed. I would apply Watson’s theory because it focuses on holistic caring (Wayne, 2021). However, the metaparadigm must also be viewed. Depression can be due to an internal issue or an external factor that stems from the environment or health problems. The nurse must understand the nursing concepts to provide appropriate care.
