Earlier, and about, I stumbled across multiple sources claiming that nursing is not a STEM major. I found the fact they stated that to be somewhat insulting and that those people genuinely have only a vague idea of what nursing is.
Is nursing science-based? Of course, nursing is science-based! We take a lot of the same pre-requisites that medical students do, and most of the "hard" sciences are not "allied health" nursing classes that the majority assume they are. We have to take the same Chemistries; most require a math class (many are demanding Statistics as well as pre-calculus... some I have seen need calculus), nurses also take Anatomy and Physiology I & II, Microbiology, Pathophysiology, and several various clinical sciences about the nursing field.
Technology? Go into an ICU, find out for yourself. Of course, nursing is technology-based, and it is becoming more than ever! Nurses today have to learn the mechanics and inner workings of so many medical chartings and screenings as well as the machines that are keeping people alive and those machine's functions. Overall, there are few fields more technology-based than nursing.
Engineering? In the classical sense, nursing isn't engineering. However, that is a particular subgroup, and one could argue that nursing does have to work with technology to in many cases, keep a patient alive.
Mathematics? Nursing is very math-focused in many areas. Drug calculations and dosages are everyday math that nurses have to chart and be aware of that can very well interfere with a patient's wellbeing. Several other factors could also be considered mathematical. Are we engineers or accountants? No. But is it a field that uses mathematics daily? Absolutely!
I believe the above reasons should qualify for nursing for "STEM." Further, we have a shortage of trained nurses in this country to meet the demand of today's healthcare system; why not consider it a STEM profession especially given the real need of them in today's society? Additionally, supporting women by counting them as a STEM field would increase the numbers and provide scholarships for women in healthcare across the nation. I fail to see why many academic institutions frown upon today's nurses given that it is no longer a "female-only" profession, it no longer provides horrible pay comparatively (it won't necessarily buy you a Ferrari, but it will very much so allow you to live a comfortable lifestyle in many locations), and it provides a real value to society.
