Total Parenteral Nutrition: An Overview

The purpose of this research is to provide an overview of the concept of total parenteral feeding, or total parenteral nutrition (TPN), and of some of the major issues surrounding the concept. Parenteral feeding refers to nutrition received other than through the intestines, or by digestion. In essence, parenteral feeding is nutrition received through an intravenous administration of a solution. TPN indicates that all of an individual's nutrition requirements are received intravenously.

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 respond to these environments through adaptation.

The central components of this approach to patient care are (1) adaptation, (2) conservation, and (3) holism (Levine, 1973). Each of these components is relative to TPN. Adaptation requires that a patient respond to her or his environments. Conservation implies the maintenance of a proper balance between nursing intervention coupled with patient participation on the one hand and safe limits of the patient's ability t...
