Integrate theory and science into EBP

How do you integrate theory and science into EBP? What are effective leadership characteristics? What is Systems Thinking and how does it relate to Leadership in Advanced Practice? In Zaccagnini, the reader is presented with brief summaries of 18 theories of nursing. Choose one that may underpin your nursing practice and describe why that theory supports your practice or choose another theory/model that you currently use or would like to implement in your setting.
