Describe one biomedical theory or model frequently used in health care and provide your rational for how it relates to improved patient outcomes.

Biomedical Sciences in Nursing
Theories from the biomedical sciences have shaped nursing practice, as well as research, throughout the years. In order to engage in the highest level of practice and aid in addressing current and future issues in health care, it is important for nurses to become more cognizant of these theories.
For this Discussion, you will differentiate among theories within the basic, or pure, sciences, and consider how they may be applied to improve outcomes in health care.
Example of theories:
1)      Web of causationby MacMahon and Pugh (1970) developed the concept of  “chain causation,” later termed the “web of causation.”
2)      The Germ Theory and Principles of Infectionby Louis Pasteur, he first proposed the germ theory in 1858
3)      The Natural History of Diseasewhich refers to the progress of a disease process in an individual over time. In their classic model, Leavell and Clark (1965) described two periods in the natural history of the disease, prepathogenesis and pathogenesis (Primary prevention, secondary prevention and tertiary prevention).
4)      Homeostasis Theoryby Claude Bernard, a physiologist in the 20^th century who first conceived the idea of homeostasis.
5)      Stress and Adaptation: General Adaptation Syndromeby Walter Canon who developed the concept of fight or flight to explain the body’s reaction to emergencies.
6)      Theory of Immunity and Immune Function: the immune system comprises a complex, coordinated group of systems that produces physiologic responses to injuries or infection.
7)       Genetic Principles and Theories: The Human Genome Project is an organized effort initiated in 1990 and completed in 2003 to create a biologically and medically full database of the genome structure and sequence in humans.
To prepare:

• Review the concepts and principles of the various biomedical theories and models presented in this week’s Learning Resources, and consider how they influence clinical practice. Which biomedical theories and models are used most frequently in health care? How do they relate to improved health outcomes? Reflect on your specific practice area and identify at least one biomedical theory or model that is utilized.

By tomorrow 7/25/17, post 550 words essay in APA format with 3 references from the list below, that include the level one heading as numbered below:  
post a cohesive response that addresses the following:
1)       Describe one biomedical theory or model frequently used in health care and provide your rational for how it relates to improved patient outcomes.
2)       Describe one biomedical theory or model that is utilized in your specific practice area. (I’m a CRITICAL CARE CARDIOVASCULAR NURSE). Provide at least two examples related to its application
