Title: Nursing Theory and Conceptual Framework


1
Nursing Theory and Conceptual Framework
  • N1111 Nursing Concepts

2
Science
  • Science - a method of bringing together facts and
    giving them coherence and integrity.
  • Scientific inquiry - five aspects
  • hypothesis
  • method
  • data collection
  • results
  • evaluation

3
Theory
  • Theory - group of related concepts that explain
    existing phenomena and predict future events.
  • Elements
  • inclusiveness
  • consistency
  • accuracy
  • relevance
  • fruitfulness
  • simplicity

4
Nursing Science
  • Nursing science is a collection of data related
    to nursing that may be applied to the practice of
    nursing
  • Developing the science and practice of nursing is
    an essential component of the discipline,
    generating knowledge that supports and advances
    healthcare.
  • Conceptual models and nursing theories evolve
    from nursing science.

5
Conceptual Framework
  • Set of concepts (constructs) and propositions
  • concepts (constructs) describe ideas about
    individuals, groups, situations, events
  • propositions show relationship

6
Concepts/constructs
  • Person - all human beings
  • individuals, families, communities, groups
  • Environment - factors that affect individuals
  • internal and external
  • Health - state of well-being
  • Nursing - Is, Do, Interact

7
Theory
  • Explains or describes nursing
  • More specific than concepts and propositions
  • Theories relate concepts by using definitions
    that state significant relationships
  • Foundation for nursing knowledge

8
Levels of Theory
  • Grand Theory, e.g. Rogers Theory of Unitary Man
  • Middle Range Theory, e.g., Jacobs Grief or Older
    Women

9
Selected Theorists
  • Nightingale - Environment
  • Orem - Self Care
  • Roy - Adaptation
  • Watson - Science of care

10
Non-Nursing Theories
  • General Systems
  • Whole and its parts
  • Maslows Hierarchy of Human Needs
  • motivation toward fulfilling needs
  • prioritize needs
  • Lewins Change Theory
  • unfreezing, movement, refreezing

11
Gordons Functional Health Patterns
  • Nurses focus on the whole
  • FHP delineate human needs
  • focus on behaviors that occur with time
  • present total picture
  • represent basic health needs that develop as
    people strive to meet those needs
  • patterns are interrelated
  • provide framework for human assessment

12
Application
  • Gordon
  • comprehensive discussion of client needs
  • Maslow
  • hierarchy for ranking the needs
  • Systems
  • analysis of relationships, purposes, reasons, and
    tasks

13
Patterns
  • Health Perception/Health Management
  • Activity and Exercise
  • Nutrition and Metabolism
  • Elimination
  • Sleep and Rest
  • Cognition and Perception
  • Other - Psychological functioning

14
Critical Thinking Exercise
  • Steps to accomplish task
