when severely challenged”. Conservation allows individuals to effectively respond to the changes their body faces, while maintaining their uniqueness as a person. Key Concepts of the Conservation Model The central concept of Levine's theory is conservation. When a person is in a state of conservation, it means that individual has been able to effectively adapt to the health challenges, with the least amount of effort. Myra Levine described the Four Conservation Principles. These principles focus on conserving an individual's wholeness: Conservation of energy: Making sure the client does not expend too much energy, through rest and exercise. Example: Making sure one's client gets enough sleep and balanced nutrition. Conservation of structural integrity: Doing activities or tasks that will aid in the client's physical healingExample: Helping the client stay active and promoting good personal care. Conservation of personal integrity: Helping clients maintain uniqueness and individualityExample: Giving clients choice in how to receive care. Conservation of social integrity: Assisting the patient in maintaining social and community ties will increase their support system during their time in hospital, and will also help the client's sense of self-worth.Example: Making a pastor available to maintain religious ties during hospitalization. Nursing Process Using Levine’s Model Assessment- The collection of facts, by way of interviews and observation with the patient (considering conservation principles) Judgement (Trophicognosis)- The application of nursing diagnoses which will provide the collected facts with meaning in the context of the patient's circumstance Hypotheses- The application of interventions that aim to maintain the patient's wholeness and promote their adaptation in the current situation Interventions- The use of interventions will test the nurse's hypotheses Evaluation- Assessment of the client's responses to imposed interventions.Alligood, Martha Raile (2010). Nursing theory: Utilization and application. Toronto: Mosby Elsevier. Application of the Nursing Process in Levine’s Conservation Model Assessment- The nurse will observe and speak with the patient, in conjunction with medical reports, results and diagnostic studies to gather information- referred to as the collection of provocative facts. Patients will be assessed for challenges to their external and internal environments that may impede their ability to achieve complete wellness and health. Areas focused on which may present such challenges are: Energy Conservation- the balance between energy expenditure and the client's energy supply Structural Integrity- the defense system for the body Personal Integrity- the client's sense of self-worth, independence and validation Social Integrity- how well one can be part of a social
