Cooperate with interdisciplinary teams and institutions to determine whether environmental exposure will affect regional health.
Conduct or participate in research to identify and control environmental exposures that adversely affect human health.
In fact, this role includes visits to decide to use strips or fragments of paint inside the child's house, or to decide to use a badly ventilated wood stove in the asthma home. It also includes evaluating the conditions that enter the work site and affect the health and safety of workers (ergonomic hazards, exposure to chemicals, or mechanical hazards such as insufficiently protected conveyor belts) I will. In addition, the nursing act itself is very harmful. Appendix B contains discussion on the dangers of nurses (and other health professionals).
An example of a nurse as an investigator is the situation of the Brownsville Texas state at the border with Mexico in 1992. Nurses working at the local community hospital's birthing department said they seemed to have some rare neonates born of relatively rare but birth defective brain malformations. After that, the nurse confirmed all the birth records of the previous year, and found that the incidence of children born with this defect in the institution was significantly higher than the incidence of the whole country. Further investigations indicate that groundwater and surface water sources are contaminated with chemicals known to cause this type of undesirable health effects (Suro, 1992) (see Box 1) .
Since the information obtained from the history is important to all other care activities related to environmental hygiene, the start of environmental health history is another research activity, the most important for improving the environmental health content of nursing practice It is one of actions. Throughout the history of the environment, nurses can know that patients and clinicians are not suspecting exposure to hazardous substances as pathogens of existing symptoms and diseases. Methods and tools for obtaining a complete environmental health record are well documented (Goldman and Peters, 1981; Tarcher, 1992). A sample form for obtaining a comprehensive environmental health record is included in Appendix G. Three important issues included in all past records of adult patients are as follows:
The four basic meta-concepts in nursing include people, environment, health, and care. This person is the interaction between the patient and the nurse to promote communication. The environment may be a hospital, clinic or family member involved in communication. Health is the health condition of the person related to the person's environment and nursing care transactions and is included in the nursing care plan (Tourville & Ingalls, 2003). Henderson's personal or personal concept consists of 14 basic needs divided into biological, psychological, social and spiritual elements. Physiological components include the need for 1 to 9 Henderson. Psychology is the need for tenth and fourteenth. Sociology is the 12th and 13th needs and the spiritual element is the eleventh need (George, 2002). People need knowledge and power to carry out daily activities, and have the need to survive.
In the philosophy of personal care, we need to include all four aspects of the nurse's meta paradigm, nurse, people, environment, and health. In the process of developing my philosophy of care in the form of personal statements, I began to realize that there are concepts that seem to reappear in all the nursing philosophy and the theory we are studying: concept. Care affects individuals, medical environment, health and illness, and overall care. It does not contain words or concepts of care, and there is little definition of care. This is because care is the most important part in doing what your nurse is doing. Therefore, I decided to build my personal care concept on the concept of care.
