I would go about writing a philosophy of nursing paper in one of two ways. I am Canadian, and I know the Canadian Nurses Association has a Code of Ethics on their website. I'm sure the U.S Nurses Association has the same. The table of contents from the CNA Code of Ethics has "Nursing values defined" followed by "Nursing Values and Responsibility Statements". I would use those as a guideline.
Also, in one of our core nursing texts, there is a small segment on nursing philosohy. The book states that the nursing profession began to shift it's focus from a traditional scientific perspective to a broader focus (encompassing philosophy, and the social sciences), which was based on Thomas Kuhn's work; The Structure of Scientific Revolutions (1962). "This new way of thinking about the philosophy of science led nurses to consider that their theoretical frameworks were not simply theoretical propostions about logical relationships among concepts, but represented actual worldviews, or paradigms, in understanding the complexities of nursing. (Canadian Fundamentals of Nursing, 2001). The book goes on to describe various nursing theories and models, namely those of Florence Nightingale, Virginia Henderson, Dorothy Orem, Hildegard Peplau, Jean Watson, Newman, among many others.
I would ask your instructor for clarification...philosophy based on sound nursing ethics/principles/standards, from a theoretical point of view, or both?
I hope I haven't confused you more than anything...I hope it helps! The book by Kuhn is a classic. I found it very hard to read, yet it really shifted my perspective of science. It's worth reading if you can stomach it!
Best wishes from a snow covered city!
