My daughter is entering high school and has a high math/science aptitude. She's been invited to an engineering program while in high school. She at one time talked about becoming a nurse, because I'm doing it so of course it's cool.
I talked to her about what a nurse does, and she was fine with that, but she also thought that nurses have a lot more to do with patient diagnosing (the medical diagnosis, not a nursing diagnosis) than they actually do.
The biggest thing that helped her decide to stay the course with engineering is that the child LOVES math. I mean seriously LOVES math. While I do not want to belittle the math that nurses do for drug calculations, because it's so critical that we not mess it up, in the math world it's just not very complicated or advanced math. I showed her one of the most complex drip calculations that is in my book, and she was shocked. She said "Mom, I was doing that math in 5th grade". (She was in an accelerated math program.) She was even more shocked when I told her that many of the people she'd be working with as a nurse are seriously challenged by this level of math. She decided that while she still doesn't know what area of engineering she wants to go into, that's the general direction she's heading into.
I'm telling you this long story because you need to think about how much you love math and science. Nursing requires a core knowledge of quite a bit of *natural* science, but doesn't use much if any in the way of physics and "hard" science. If you truly love working with math and "hard" science, and want to be working with people at that level in those areas, you may not find nursing to be a good option for you.
I would strongly recommend that you find a way to shadow a nurse in his/her job, or find some nurses to have an in-depth conversation with regarding what nursing entails.
Now, there *are* some areas of nursing, specifically research, that I understand to be much heavier in both the higher math and the "hard" science. Those areas require more schooling and advanced degrees, usually, but if you can research more about them, it might be a nursing area that holds a lot of interest for you. One of the things that attracts me so much about nursing is that there are myraid areas to work in so if one specialty doesn't work out, others might be just right.
