Philosophy of Nursing

I need to elaborate on this for an online discussion,

“As you considered the four central concepts of professional nursing from the lesson, you thought about how each of those is incorporated into your own philosophy of nursing. Select one of those four central concepts, and explain how it is exemplified in your own philosophy of professional nursing.”

this is the book that we are using,

Hood., and Lucy. Leddy & Pepper’s Conceptual Bases of Professional Nursing, 8th Edition. Lippincott Williams & Wilkins, 2013. VitalBook file.
