Study Notes

Input and Output

Input and output involve exchanging matter, energy, and information between a client and their environment.

Feedback

System outputs provide feedback for future inputs, enabling corrective actions to enhance or stabilize the system.

Negentropy

A process that conserves energy while increasing organization and complexity, aiming for a stable state of higher wellness.

Stability

A dynamic balance allowing energy exchanges without disrupting the system, indicative of optimal health.

Environment

Encompasses internal and external forces surrounding the client, influencing and being influenced by them.

Created Environment

Unconsciously developed by the client to express system wholeness and maintain stability and perceptual protection.

Client System

A composite of five variables:
- Physiological: body structure and function.
- Psychological: mental processes interacting with the environment.
- Sociocultural: effects of social and cultural conditions.
- Developmental: age-related processes.
- Spiritual: spiritual beliefs and influences.

Basic Structure

Client as a system is depicted as concentric rings, with the inner core representing basic survival factors.

Lines of Resistance

Broken rings surrounding the core provide resource factors to help clients defend against stressors.

Normal Line of Defense

The outer solid circle indicating the adaptive health level developed over time, measuring wellness deviations.

Flexible Line of Defense

The outer broken ring acts as a protective buffer against stressors, serving as the first defense mechanism.

Health

A dynamic continuum ranging from wellness to illness, with optimal wellness achieved when all system needs are met.

Wellness

Occurs when all system components interact harmoniously and all needs are fulfilled.

Illness

Represents instability and energy depletion, positioned at the opposite end of the wellness continuum.

Stressors

Tension-producing stimuli that can disrupt system stability, categorized into:
- Intrapersonal: occurring within the individual.
- Interpersonal: arising between individuals.
- Extrapersonal: external circumstances affecting the individual.

Degree of Reactions

Refers to system instability resulting from stressors invading the normal line of defense.

Prevention as Intervention

Intentional actions aimed at helping clients maintain stability through proactive or reactive means.

Three Levels of Intervention

Primary: Action taken before a stressor is encountered to reduce reaction likelihood.
Secondary: Treatment initiated after symptoms appear, enhancing internal resistance.
Tertiary: Follow-up actions after secondary prevention to support recovery.

Prevention

Focuses on mitigating the effects of stressors on the body, classified into:
- Primary: Before system reacts to stressors.
- Secondary: After reaction, based on existing systems.
- Tertiary: After facing treatment through secondary strategies.

Major Assumptions of Neuman’s Systems Model

Human beings, as clients, exist as open systems in constant interaction with their environment, structured in layers (physical, psychological, socio-cultural, developmental, spiritual) represented as concentric circles.

Health and Environment

Health is wellness achieved through harmony among all client system parts; the environment includes influences from various stressors significant to system stability.

Case History Overview - Mr. Renato H.

Hospital admission due to severe shortness of breath and chest pain resulting from acute COPD exacerbation and right-sided heart failure.
Symptoms included appetite loss, difficulty swallowing, weight loss, and family visits.
Chest x-ray revealed cardiac enlargement; prescribed oxygen therapy, COPD medications, and nutritional support; expressed desire to avoid hospital death.

Application of Neuman's Model in Care

Focus on mutual nurse-client partnership, addressing physiological stressors as priorities while also considering psychological, developmental, sociocultural, and spiritual influences on patient status.
