Nursing Theories and Nursing Process

Concepts of Nursing Theory

• Definition: A systematically interrelated set of concepts or hypotheses to explain or predict phenomena.
• Functions:
• Describes, explains, predicts, and prescribes phenomena in nursing practice.
• Guides nursing processes and provides a foundation for nursing autonomy and professionalism.

Phases of Theory Application

1. Analyzing concepts
2. Constructing relationships
3. Testing relationships
4. Validating relationships

Distinction Between Theory and Model

• Theory: A systematic framework for understanding phenomena.
• Model: A hypothetical or theoretical representation of real-world processes (e.g., hospital organizational chart).

Application of Theories in Community Health Nursing

Scope and Influence

• Theories provide a foundation for community health nursing practice across various specialties and levels.
• Influence on nursing practice (Fawcett, 1992):
• Identify standards, settings, processes, and technologies for nursing care.
• Direct delivery of nursing services and quality assurance programs.
• Guide development of systems like care plans, admission databases, and discharge summaries.

Key Outcomes of Theory Integration

• Improved autonomy and professionalism in nursing.
• Evidence-based and systematic delivery of nursing care.
• Enhanced understanding of complex realities in nursing practice.

Key Concepts in Nursing Theories and Models

Nursing theories and models are built on four central concepts:

1. Client/Patient (Person): Refers to individuals or groups, focusing on their interaction with health and environment.
2. Health: Encompasses well-being, optimal functioning, and the effects of nursing interventions.
3. Environment: Highlights the influence of physical and social surroundings on health.
4. Nursing: Involves the actions and processes that bring about positive health outcomes.

---

Propositions Linking Nursing’s Metaparadigm Concepts

1. Person and Health: Focuses on life processes, well-being, and optimal functioning, whether individuals are sick or well.
2. Person and Environment: Examines human behavior in relation to their environment during normal and critical life events.
3. Health and Nursing: Emphasizes nursing actions that promote positive health changes.
4. Person, Environment, and Health: Addresses the interaction between individuals and their environment, aiming for holistic care.

Florence Nightingale’s Theory of Environment

Core Principles

• Nursing optimizes conditions for nature to act on the patient.
• Focuses on a clean, healthy environment as crucial for healing and health maintenance.

Key Concepts in Nightingale’s Theory

1. Human Beings:

• Emphasizes the relationship between individuals and their environment.
• Does not specifically define “person.”

1. Environment:

• Central to health, with importance placed on fresh air, light, warmth, cleanliness, quiet, and proper diet.
• Poor environments lead to stagnant air and sickness.

1. Health:

• Views health promotion as integral to nursing, focusing on both the sick and the healthy.

1. Nursing:

• Nurses act as observers, facilitating healing by ensuring a healthy environment.
• Nursing is an art, while medicine is a science.

Key Statements from Nightingale (1859/1992)

• Health of Houses: Poorly designed houses affect the healthy as badly as poorly constructed hospitals affect the sick.
• Ventilation and Warming: Maintain pure air for the patient without causing chilling.
• Five Essentials for Healthful Houses: Pure air, pure water, efficient drainage, cleanliness, and light.

Assumptions of Nightingale’s Theory

• “Nature alone cures,” and a healthy environment supports healing.
• Nurses should meticulously observe and report patient conditions.
• Nurses must follow medical plans honestly but with autonomy.

---

Importance of Nightingale’s Theory in Modern Nursing

• Focus on Environment: Forms the basis for community health nursing practices.
• Health Promotion: Highlights the role of nurses in preventive and promotive health care.
• Holistic Approach: Emphasizes caring for patients in their entirety—body, mind, and environment.

Betty Neuman’s Systems Theory:

Betty Neuman’s Systems Theory emphasizes how a patient/client system responds to environmental stressors. It focuses on using nursing interventions at primary, secondary, and tertiary levels. These interventions promote wellness and stability.

---

Basic Assumptions of Neuman’s Systems Theory

1. Patient System:

• A unique combination of factors and characteristics that respond dynamically to stressors.
• Includes a normal line of defense (baseline health) and a flexible line of defense (temporary protection from stressors).

1. Stressors:

• Known, unknown, or universal elements that disturb stability.

1. Lines of Defense:

• Flexible Line of Defense: Protects the system temporarily; breaks down under severe stress.
• Normal Line of Defense: Indicates usual stability; deviations signal health issues.
• Lines of Resistance: Internal factors that realign the system to wellness after stress.

1. Dynamic Interaction:

• The patient system constantly interacts with the environment, engaging in energy exchanges.

---

Levels of Prevention in Nursing Interventions

1. Primary Prevention:

• Focuses on risk reduction and preventing stressors before they impact the system.
• Example: Health education to prevent illness.

1. Secondary Prevention:

• Reduces the harmful effects of stressors through early treatment.
• Example: Screening for diseases.

1. Tertiary Prevention:

• Aims to restore wellness and reconstitute the system.
• Example: Rehabilitation after illness.

---

Application of Neuman’s Theory at Community Level

• Represented through concentric circles:

1. Core: Basic amenities for survival and resource utilization (e.g., food, water, shelter).
2. Lines of Resistance: Community efforts like population control and health education.
3. Normal Line of Defense: Existing systems like healthcare infrastructure and sanitation regulations.
4. Flexible Line of Defense: Dynamic buffers such as disaster preparedness and road maintenance.

• Example: Disaster alert systems functioning as a flexible line of defense to protect the community.

---

Application at Individual Level

1. Person:

• An open system comprising five interrelated variables:
  • Physiological (biological functions)
  • Psychological (mental health)
  • Sociocultural (social and cultural influences)
  • Developmental (growth and life stages)
  • Spiritual (belief systems and values)

1. Health:

• A dynamic state of stability when all systems function harmoniously.
• Wellness exists when the normal line of defense remains intact.

1. Environment:

• Includes internal, external, and created stressors that influence health positively or negatively.

1. Nursing:

• A holistic approach to promote wellness at individual, family, and community levels.
• Uses primary, secondary, and tertiary prevention modes to achieve optimal wellness.

---

Nursing Response to Stressors

• Flexible Line of Defense Activation:
• Alarms the system to protect the normal line of defense.
• Failure leads to deviation from normal health and illness development.
• Continuous Stress Exposure:
• Weakens defenses, causing instability and illness.

---

Key Features in Application

• Focuses on holistic care, addressing physical, mental, social, and spiritual dimensions.
• Utilizes prevention-based interventions to maintain and restore stability.
• Adaptable to both individual and community-level care, ensuring broad applicability in nursing practice.

Roy’s Adaptation Model:

Developed by Sister Callista Roy, this model is a framework grounded in systems theory. Its primary goal is to assist clients in achieving their highest level of functioning through adaptation. The model views individuals as biopsychosocial beings continuously interacting with their environment and adapting to stimuli.

---

Core Concepts

1. Person (Man)

• A dynamic entity with input (stimuli) and output (behavior).
• Individuals are influenced by internal and external stimuli and adapt through a continual process.
• Outputs (behaviors) result from attempts to adapt to inputs and can be adaptive or maladaptive.

2. Adaptation Modes

Roy identified four key modes through which individuals adapt:

1. Physiological Mode: Adaptation via internal physiological processes (e.g., maintaining homeostasis).
2. Self-Concept Mode: Adaptation shaped by life experiences and personal perceptions.
3. Role-Function Mode: Adaptation related to one’s roles in society and expectations of those roles.
4. Interdependence Mode: Adaptation through relationships and interactions with others.

3. Health

• Health exists on a continuum from perfect wellness to complete illness.
• Defined by the ability to adapt to internal or external stimuli.
• Example: A nursing student facing psychological trauma but successfully adapting demonstrates a high degree of health.

4. Environment

• The environment encompasses all internal and external factors influencing behavior.
• Categorized stimuli:
• Focal Stimulus: The immediate stimulus requiring adaptation.
• Contextual Stimuli: Other contributing stimuli present in the situation.
• Residual Stimuli: Environmental factors with unknown effects on the individual.

5. Adaptation

• A process and outcome involving conscious awareness, choice, and integration of human and environmental factors.
• Coping mechanisms may be innate (natural) or acquired (learned).

---

Application in Nursing

1. Nursing Process

The nurse’s role is to assist the patient in overcoming stimuli through the four adaptive modes. This process involves:

• Behavioral Assessment (Output):
• Identify adaptive or maladaptive responses.
• Example: A suspected tuberculosis patient’s physical symptoms (e.g., fever, cough, weight loss) are evaluated first.
• Stimuli Assessment (Input):
• Assess focal, contextual, and residual stimuli.
• Example: Investigate sputum for TB bacteria, household crowding, dietary habits, or socioeconomic factors.
• Nursing Diagnosis:
• Identify whether the patient’s behavior is adaptive or maladaptive.
• Goal Setting and Planning:
• Manipulate stimuli to promote optimal adaptation.
• Implementation and Evaluation:
• Intervene and assess outcomes to determine if goals are met.

2. Example Application

For a community health nurse managing a tuberculosis case:

• Behavioral symptoms (fever, cough, fatigue) are documented.
• Environmental stimuli (crowded living conditions, dietary patterns) are assessed.
• A plan is implemented to address stimuli and promote adaptation (e.g., health education, treatment adherence).

---

Key Definitions in Roy’s Adaptation Model

• Adaptation: Conscious processes for achieving harmony between individuals and their environment.
• Stimulus: The interaction point between a human system and the environment that provokes a response.
• Focal Stimulus: The immediate concern (e.g., illness).
• Contextual Stimuli: Related influences (e.g., family dynamics, work stress).
• Residual Stimuli: Factors with unknown or unclear effects.
• Self-Concept: Beliefs and feelings about oneself at a given time.
• Role: Functional societal units tied to others for relational integrity.
• Interdependence: Relationships that meet needs for affection, development, and resource sharing.

Orem’s Self-Care Model, developed by Dorothea E. Orem, emphasizes the critical role of self-care in maintaining health and managing illness. The model integrates three interrelated theories, offering a comprehensive framework for nursing practice. Below is an organized summary of its key components:

---

Concepts of Orem’s Self-Care Model

1. Core Theories

1. Theory of Self-Care:

• Focuses on the activities individuals initiate to maintain life, health, and well-being.
• Self-care includes universal requisites like air, water, food, rest, and social interaction, among others.

1. Theory of Self-Care Deficit:

• Occurs when individuals cannot meet their self-care demands.
• Nursing intervention is required to bridge the gap between self-care demands and the patient’s abilities.

1. Theory of Nursing Systems:

• Describes the nursing care required based on the patient’s ability to perform self-care.
• Three nursing care systems:
  • Wholly Compensatory: For individuals unable to perform self-care.
  • Partially Compensatory: For individuals needing assistance with some self-care activities.
  • Supportive-Educative: For individuals capable of self-care but requiring guidance or education.

---

Key Components of the Model

Person:

• A biopsychosocial being capable of self-care.
• The core of the model revolves around the individual’s ability to perform self-care to maintain life and optimal health.

Health:

• Defined as the individual’s capacity to adapt to the environment and maintain functioning through self-care.
• Self-Care Deficit indicates a state of illness where individuals cannot meet one or more self-care requisites, such as:
• Air, water, and food.
• Waste excretion.
• Activity and rest.
• Social interaction and solitude.
• Safety from hazards.
• Mental well-being.

Environment:

• Seen as a negative influence on self-care abilities.
• Includes physical and social factors that affect health and distract from self-care activities.

Nursing:

• The nurse’s primary role is to fill self-care deficits by providing care or empowering the patient to regain self-care abilities.
• Nursing care focuses on:
• Enhancing the patient’s independence.
• Promoting health education and development.

---

Nursing Process and Application

1. Assessment:

• Identify self-care deficits by evaluating the patient’s needs and abilities.

1. Planning:

• Categorize the patient into one of the nursing systems (wholly compensatory, partially compensatory, or supportive-educative).
• Develop a care plan tailored to their needs.

1. Implementation:

• Use one or a combination of the following five nursing methods:
  1. Acting for the patient.
  2. Guiding the patient.
  3. Supporting the patient (physically or psychologically).
  4. Providing an environment conducive to development.
  5. Teaching the patient self-care.

1. Evaluation:

• Assess the outcomes of nursing interventions and adjust the care plan if necessary.

---

Applications in Community Nursing

• Promoting healthy lifestyles and self-care practices.
• Providing partial or full compensatory care in:
• Extended care facilities.
• Terminally ill centers.
• Old age homes.
• Supporting families to meet self-care needs during chronic illnesses or rehabilitation.

Nola J. Pender’s Health Promotion Model (HPM)

The Health Promotion Model (HPM) by Nola J. Pender, first introduced in 1982 and revised in 1996, emphasizes a proactive approach to health. Unlike models focusing on disease prevention, HPM seeks to improve overall well-being and promote healthy behaviors. Below is a structured summary of the model’s components:

---

Key Concepts of HPM

Health

• Defined as a positive dynamic state, not merely the absence of disease.
• Health promotion aims to enhance well-being and enable individuals to reach higher levels of health.

Person

• Viewed as a multidimensional being who interacts with the environment to pursue health.

---

Focus Areas of the Model

HPM centers around three major components:

1. Individual Characteristics and Experiences
2. Behavior-Specific Cognitions and Affect
3. Behavioral Outcomes

---

1. Individual Characteristics and Experiences

Personal Factors

• Personal factors are predictors of behavior and vary based on the nature of the health behavior. These are categorized as:

1. Biological Factors:
   • Examples: Age, gender, body mass index, pubertal status, aerobic capacity, and agility.
2. Psychological Factors:
   • Examples: Self-esteem, motivation, competence, perceived health status, and health definitions.
3. Sociocultural Factors:
   • Examples: Race, ethnicity, education, socioeconomic status, and acculturation.

Prior Behavior

• Refers to the frequency and patterns of similar past behaviors.
• Influences future behavior through direct and indirect effects.

---

2. Behavior-Specific Cognitions and Affect

Perceived Benefits of Action

• Anticipated positive outcomes that result from engaging in health-promoting behavior.

Perceived Barriers to Action

• Real or imagined obstacles or costs associated with performing the behavior.

Perceived Self-Efficacy

• Confidence in one’s ability to successfully organize and execute health-promoting behaviors.

Activity-Related Affect

• Positive or negative feelings before, during, and after engaging in health-promoting behaviors.
• A positive affect increases self-efficacy and the likelihood of action.

Interpersonal Influences

• Cognitive factors arising from interactions with others, including:
• Norms: Expectations from significant others.
• Social Support: Emotional and practical encouragement.
• Modeling: Learning behaviors by observing others.
• Influences are typically from family, peers, and healthcare providers.

Situational Influences

• Personal perceptions of the context or environment where health behavior occurs, which may facilitate or impede action.
• Examples: Availability of options, environmental aesthetics, and contextual demands.

---

3. Behavioral Outcomes

Commitment to a Plan of Action

• A planned strategy and clear intention lead to consistent health-promoting behaviors.

Immediate Competing Demands and Preferences

• Competing Demands: Uncontrollable behaviors influenced by external factors, like work or family obligations.
• Competing Preferences: Controllable alternative choices, such as selecting a healthy snack over an unhealthy one.

Health-Promoting Behavior

• The ultimate goal of HPM, defined as behavior that leads to:
• Optimal well-being.
• Personal fulfillment.
• Enhanced quality of life.

---

Assumptions of HPM

1. Each person has unique characteristics and experiences that influence actions.
2. Behavioral-specific knowledge and affect are critical motivational factors that can be modified through nursing interventions.
3. Health-promoting behaviors result in:

• Improved health.
• Enhanced functional ability.
• Better quality of life across developmental stages.

1. Competing demands and preferences can derail intentions, requiring proactive strategies.

---

Applications of HPM in Nursing Practice

• Community Health: Encouraging health-promoting behaviors in various populations.
• Education: Enhancing awareness about benefits and strategies for maintaining health.
• Clinical Settings: Tailoring nursing care to address barriers and improve self-efficacy.
• Lifestyle Modification: Supporting individuals in developing habits like regular exercise, balanced diets, and stress management.
