Chapter 12
Overview of the Conservation Model: Four Conservation Principles
Conservation of energy
Conservation of structural integrity
Conservation of personal integrity
Conservation of social integrity
Major Concepts That Form Basis of the Conservation Model
Conservation describes the way complex systems are able to continue to function even when severely challenged
Wholeness (or holism) provides the option of exploring parts of the whole to understand the whole
Adaptation is the process of change whereby the individual retains his integrity within the realities of his internal and external environment
Major Concepts of Nursing According to the Conservation Model
Person: system of systems, and in its wholeness expresses the organization of all the contributing parts; may be an individual, an individual in a group, or an individual in a community
Environment: the context in which individuals live their lives and each individual has both internal and external environments
Major Concepts of Nursing According to the Conservation Model
Health and disease are patterns of adaptive changes; concept of health implies wholeness and integrity whereas disease presents the person’s effort to protect self-integrity
Nursing is human interaction and goal of nursing is to promote adaptation and maintain wholeness
Assumptions of the Conservation Model
Person can only be understood in the context environment, including place and time
Persons are sentient, thinking, future-oriented and past-aware individuals
Every self-sustaining system monitors its own behavior by conserving the use of resources required to define its unique identity
Human beings respond in a singular, yet integrated fashion
Propositions of the Conservation Model
Emphasizes that the environment is not a passive stage setting; rather the person is an active participant in exploring, seeking, and testing the world he or she inhabits
The individual is always within environmental milieu, and the consequences of his or her awareness of the environment persistently influence the person’s behavior at any moment
Propositions of the Conservation Model
The person’s presence in the environment also influences it and, therefore, the kind of information available from it
The individual protects and defends himself or herself within the environment by gaining all the information he or she can about it
Propositions of the Conservation Model
Interaction at the interface between the individual and the environment is an orderly, sometimes predictable, but always limited process.
Consequences of the interaction is invariably the product of the characteristics of the individual and the external factors; the process of the interaction is adaptation
Propositions of the Conservation Model
Ability of every individual not only to survive but also to flourish is a consequence of the competence of the person’s interactions with the environments in which he or she functions
Person cannot be described apart from the environment in which he or she is found.
The precise environment necessarily completes the wholeness of the individual
Propositions of the Conservation Model
The goal of conservation is health
Conservation of integrity of the person is essential to assuring health and providing the strength needed to confront disability
The environment is not always “user-friendly” and successful engagement with the environment depends on the individual’s repertoire
Propositions of the Conservation Model
The nurse cannot enter a person’s environment without becoming an essential factor in it
The nurse participates actively in the patient’s environment and much of what the nurse does supports the patient’s adaptations as he or she struggles in the predicament of illness
An key element of care is restoring symmetry of response to environmental interaction
Brief Critique of the Conservation Model
Derived from deductive logic by integrating theories and concepts from related disciplines
Inductive reasoning was used to further develop the model through practice
Clear, simple, and easily generalizable
Terms are clearly defined in a manner that lends to the internal consistency of the model
Used in research and practice
The Conservation Model as a Framework for Nursing Practice
Nurse observes the patient with consideration of conservation principles and response to illness
Trophicognosis—a scientific method for gathering data into a usable form, reaching nursing care judgments, and communicating information—alternative to nursing diagnosis.
Nurse hypothesizes about the problem and the solution to develop the plan of care
The Conservation Model as a Framework for Nursing Practice
Interventions are designed to address the conservation principles and are a testing of hypotheses formulated in previous phase of process
Evaluation based on observations of responses to interventions and judgments as to whether hypotheses are supported
