   1. Consider one system in Bronfenbrenner’s theory, what system would have the greatest positive impact in managing the disease?  Explain your answer.
   2. Consider Biopsychosocial Model, which aspects of biological, psychological, and social domains are most important to understanding and promoting the patient’s health?  Explain your answer.
   3. Consider the Person-In-Environment system, how should the environment change to improve the person’s ability to live with the disease and vice versa?
