Total Parenteral Nutrition: An Overview

TPN AND THE ROLE OF THE PROFESSIONAL NURSE

There are nine principal activities associated with professional nursing (Levine, 1973). Activities numbers four and five are directly related to TPN. Activity number five is the determination, and the provision of patient nutritional needs, while activity number four is the application of fluid pressure gradient systems in nursing interventions. The professional nurse, therefore, is the health care professional most directly involved in patient TPN.

The role of the professional nurse incorporates aspects of sciences such as psychology, sociology, and physiology (Marriner, 1986) and is thus, a holistic approach to total patient care (Meleis, 1984). In this approach, the patient is the center of nursing activities. A patient, as a person, is a complex individual, who has a sense of identity (Levine, 1971). In nursing, individuals, as patients, interact with internal and external environments, and respo

care team. A primary care physician typically heads such a team, whether or not it is a formally constituted team. Many other types of health care professionals and workers, however, will usually be involved in the delivery of health care services in the home. The pre and postcheck list procedure advocated by Davis (1988) assumes particular importance in the administration of TPN in such a situation. Infusion therapy involves the administration of fluids intravenously, through the nose, or directly into the intestine. TPN involves the administration of fluids intravenously, as it is an approach to the provision of nutrition which bypasses the intestines. Basic nutrition, antibiotics, painkillers, chemotherapy, and dialysis may be provided through the use of infusion therapy (Murphy, 1982; Current Health, 1987). Although infusion therapy need not provide the total nutritional requirements for a patient, such is the case when TPN is involved. Nurse practitioners are prominent among the health care professionals who are active in the delivery of home health care services, including the administration of TPN. Nurse practitioners engage in the delivery of a wide variety of health care services without the direct su
