NURSING THEORIES - NEUMAN, ROY, & JOHNSON Flashcards
The goal of the model was to provide a holistic overview of the physiological, psychological, sociocultural, and developmental aspects of human beings.
NEUMAN’S SYSTEMS MODEL
Two Major Components of the Neuman’s Systems Model
- Stress
- Reaction to stress
Viewed as an open system in which repeated cycles of input, process, output and feedback constitute a dynamic organizational pattern.
Client (Neuman)
Using the systems perspective, the client may be an individual, a group, a family, a community, or any aggregate.
As they become more complex, the internal conditions of regulation become more complex.
Exchanges with the environment are reciprocal; both the client and the environment may be affected either positively or negatively by the other.
The system may adjust to the environment or adjust the environment to itself.
Client (Neuman)
Each layer, or concentric circle, of the Neuman model is made up of the five person variables. Ideally, each of the person variables should be considered simultaneously and comprehensively.
- Physiological
- Psychological
- Sociocultural
- Spiritual
- Developmental
(Neuman)
refers of the physicochemical structure and function of the body
Physiological (Neuman)
refers to mental processes and emotions
Psychological (Neuman)
refers to relationships; and social/cultural expectations and activities
Sociocultural (Neuman)
refers to the influence of spiritual beliefs
Spiritual (Neuman)
refers to those processes related to development over the lifespan
Developmental (Neuman)
The basic structure, or ________, is made up of the basic survival factors that are common to the species (Neuman, 1995, in George, 1996).
CENTRAL CORE (Neuman)
Factors of the Central Core include:
- System variables
- Genetic features
- The strengths and weaknesses of the system parts
(Neuman)
Is an open system and therefore is dynamic and constantly changing and evolving.
Person’s System (Neuman)
Occurs when the amount of energy that is available exceeds that being used by the system.
Stability / Homeostasis (Neuman)
Is constantly in a dynamic process of input, output, feedback, and compensation, which leads to a state of balance.
Homeostatic Body System (Neuman)
A protective accordion-like mechanism that surrounds and protects the normal line of defense from invasion by stressors.
The outer barrier or cushion to the normal line of defense, the line of resistance, and the core structure.
Acts as a cushion and is described as accordion-like as it expands away from or contracts closer to the normal line of defense.
Can be changed/altered in a relatively short period of time.
If the _______________ fails to provide adequate protection to the normal line of defense, the lines of resistance become activated.
FLEXIBLE LINES OF DEFENSE (Neuman)
An adaptational level of health developed over time and is considered normal for a particular individual client or system; it becomes a standard for wellness-deviance determination.
Represents system stability over time.
Can change over time in response to coping or responding to the environment.
An example is skin, which is stable and fairly constant, but can thicken into a callus over time.
It is considered to be the usual level of stability in the system.
NORMAL LINE OF DEFENSE (Neuman)
Protection factors are activated when stressors have penetrated the normal line of defense, causing reaction symptomatology.
Protect the basic structure and become activated when environmental stressors invade the normal line of defense.
Example: activation of the immune response after invasion of microorganisms.
If the _______________ are effective, the system can reconstitute and if the lines of resistance are not effective, the resulting energy loss can result in death.
LINES OF RESISTANCE (Neuman)
Is the increase in energy that occurs in relation to the degree of reaction to the stressor.
Begins at any point following initiation of treatment for invasion of stressors.
May expand the normal line of defense beyond its previous level, stabilize the system at a lower level, or return it to the level that existed before the illness.
RECONSTITUTION (Neuman)
Any phenomenon that might penetrate both the flexible and normal lines of defense, resulting in either a positive or negative outcome.
Are capable of having either a positive or negative effect on the client system.
The Neuman Systems Model looks at the impact of ___________ on health and addresses stress and the reduction of stress (in the form of _________).
Any environmental force which can potentially affect the stability of the system.
STRESSORS (Neuman)
A stressor is any environmental force which can potentially affect the stability of the system, they may be:
- Occur within person, e.g. emotions and feelings
- Occur between individuals, e.g. role expectations
- Occur outside the individual, e.g. job or finance pressures
- Intrapersonal
- Interpersonal
- Extrapersonal
(Neuman)
The person has a certain degree of _______ to any given stressor at any given time.
reaction (Neuman)
The nature of the reaction depends in part on the _________________.
strength of the lines of resistance and defense (Neuman)
As defined by Neuman’s model, _________ is the primary nursing intervention. __________ focuses on keeping stressors and the stress response from having a detrimental effect on the body.
Prevention (Neuman)
Occurs before the system reacts to a stressor.
It strengthens the person (primarily the flexible line of defense) to enable him to better deal with stressors, and on the other hand manipulates the environment to reduce or weaken stressors.
Includes health promotion and maintenance of wellness.
Strategies that might be used include immunization, health education, exercise, and lifestyle changes.
Primary Prevention (Neuman)
Occurs after the system reacts to a stressor and is provided in terms of existing systems.
Focuses on preventing damage to the central core by strengthening the internal lines of resistance and/or removing the stressor.
Secondary Prevention (Neuman)
Occurs after the system has been treated through secondary prevention strategies.
Offers support to the client and attempts to add energy to the system or reduce energy needed in order to facilitate reconstitution.
Tertiary Prevention (Neuman)
“Unique profession in that is concerned with all of the variables affecting an individual’s response to stress.”
Nursing (Neuman)
The focus is on the client as a system (which may be an individual, family, group, or community) and on the client’s responses to stressors.
The client system includes five variables (physiological, psychological, sociocultural, developmental, and spiritual). It is conceptualized as an inner core (basic energy resources) surrounded by concentric circles that include lines of resistance, a normal defense line, and a flexible line of defense.
Neuman’s System Model
Is an open system that interacts with internal and external environment forces or stressors
Constantly changing, moving toward a dynamic state of system stability or illness of varying degrees
Human Being (Neuman)
Is a vital arena that is germane to the system and its function.
May be viewed as all factors that affect and are affected by the system.
In Neuman Systems Model identifies three relevant _____________: (1) internal, (2) external, and (3) created.
Environments (Neuman)
The (1) _________ environment exists within the client system. All forces and interactive influences that are solely within the client system’s boundaries make up this environment.
The (2) _________ environment exists outside the client system.
The (3) _________ environment is unconsciously developed and is used by the client to support protective coping.
(1) internal
(2) external
(3) created
(Neuman)
Is defined as the condition or degree of system stability and is viewed as a continuum from wellness to illness. When system needs are met, optimal wellness exists. When needs are not satisfied, illness exists. When the energy needed to support life is not available, death occurs.
Health (Neuman)
A system in which there is a continuous flow of input and process, output and feedback. It is a system of organized complexity, where all elements are in interaction.
Open System (Neuman)
