A nurse, by definition is a person trained to care for the sick or infirm, especially in the hospital. Although, this is related to the twenty-first century definition of a nurse it has not always been viewed this way. Nursing today is not at all how it was in the past and is continuously changing and improving. There are many differences between the centuries from when nursing first came about, dating all the way back to the early 1600’s. Although there were a lot of differences there are still similarities and characteristic that are seen in todays nursing and will continue to be practiced in the future of nursing, both as a discipline and as a profession.
