Neuman Systems Model
The Neuman systems model is a nursing theory based on the individual's relationship to stress, the reaction to it, and reconstitution factors that are dynamic in nature. The theory was developed by Betty Neuman, a community health nurse, professor and counselor. The central core of the model consists of energy resources (normal temperature range, genetic structure, response pattern, organ strength or weakness, ego structure, and knowns or commonalities) that are surrounded by several lines of resistance, the normal line of defense, and the flexible line of defense. The lines of resistance represent the internal factors that help the patient defend against a stress (biology), stressor, the normal line of defense represents the person's state of equilibrium, and the flexible line of defense depicts the dynamic nature that can rapidly alter over a short period of time. The purpose of the nurse is to retain this system's stability through the three levels of Primary prevention, prevent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stress (biology)
Stress, either physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. Stress is the body's method of reacting to a condition such as a threat, challenge or physical and psychological barrier. There are two hormones that an individual produces during a stressful situation, these are well known as adrenaline and cortisol. There are two kinds of stress hormone levels. Resting (basal) cortisol levels are normal everyday quantities that are essential for standard functioning. Reactive cortisol levels are increases in cortisol in response to stressors. Stimuli that alter an organism's environment are responded to by multiple systems in the body. In humans and most mammals, the autonomic nervous system and hypothalamic-pituitary-adrenal (HPA) axis are the two major systems that respond to stress. The sympathoadrenal medullary (SAM) axis may activate the fight-or-flight response through the sympathetic nervous system ...

Primary Prevention
Preventive healthcare, or prophylaxis, consists of measures taken for the purposes of disease prevention.Hugh R. Leavell and E. Gurney Clark as "the science and art of preventing disease, prolonging life, and promoting physical and mental health and efficiency. Leavell, H. R., & Clark, E. G. (1979). Preventive Medicine for the Doctor in his Community (3rd ed.). Huntington, NY: Robert E. Krieger Publishing Company. Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices, and are dynamic processes which begin before individuals realize they are affected. Disease prevention relies on anticipatory actions that can be categorized as primal, primary, secondary, and tertiary prevention. Each year, millions of people die of preventable deaths. A 2004 study showed that about half of all deaths in the United States in 2000 were due to preventable behaviors and exposures. Leading causes included cardiovascular disease, ...

Nursing Theory
Nursing theory is defined as "a creative and rigorous structuring of ideas that project a tentative, purposeful, and systematic view of phenomena". Through systematic inquiry, whether in nursing research or practice, nurses are able to develop knowledge relevant to improving the care of patients. Theory refers to "a coherent group of general propositions used as principles of explanation". Nursing theory Importance In the early part of nursing's history, there was little formal nursing knowledge. As nursing education developed, the need to categorize knowledge led to development of nursing theory to help nurses evaluate increasingly complex client care situations. Nursing theories give a plan for reflection in which to examine a certain direction in where the plan needs to head. As new situations are encountered, this framework provides an arrangement for management, investigation and decision-making. Nursing theories also administer a structure for communicating with other nurse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
