the welfare of good health.
This part is confusing.
I think the most important thing about this essay, the most impressive thing, is that you capture the unique combination of knowledge, skill, and kindness that characterizes the nursing profession.
You should framed these two great paragraphs between an equally great introduction and conclusion paragraph.
Most importantly, and in that first sentence of the essay has got to change. It is obvious, confusingly worded, and a little too simple. That first sentence is like a missed opportunity to say something brilliant it will stick in the reader's mind and make you memorable.
