A few things I would like to know is:
Are there specific majors I would need to take in college in order to enter this profession?
Would I be able to use these same majors to apply to medical school?
Are there different kinds of nursing? What are they?
What is the average income per year?
Is this a very competitive area of study? job competition?
What are the hours like?
I can’t think of anything else at the moment but any additional information you could give me would be very helpful, or links explaining some of the details,
thank you

people go to special schools of nursing for years, so there’s not enough room here to tell you. there are as many different kinds of nursing as there are medical specialities. you can even get as high as a doctorate in nursing. I can’t answer all your questions, but I do know that nurses can always find jobs wherever they go. this site will help more than I can.
Nursing is a very good field to enter but only if you have a nurturing desire, do not mind sick people and bodily fluids getting on you, and have a mind for science and biology.
If you faint at the sight of blood, you do not need to be a nurse.
In order to be a registered nurse, you would have to major in Nursing in college. You can either get an Associate’s degree (ASN) or a Bachelor’s degree (BSN).
A BSN is a 4-year program and an ASN is a 2- or 3-year program. Community colleges that offer nursing degrees almost always only offer an ASN. Regular 4-year colleges and universities are the ones that offer BSNs.
So should you go for an ASN or BSN? A BSN will take you a lot farther over the course of your career, but a lot of people don’t have the time or money to go this route. For this reason, some people choose to get an ASN first, find a job, and then do a BSN completion program to round up the last few credits needed to get the actual Bachelor’s designation. If you do this, your employer will most likely cover the tuition for the completion program.
You can get into medical school with any 4-year undergraduate degree, so long as you have completed certain prerequisites. These prerequisite college courses are generally a year each (i.e., 2 semesters each) of Biology, Chemistry, Organic Chemistry, and Physics. If you work hard, you could take these prerequisite courses while in nursing school. You would then need to take the MCAT and apply to med school just like any other candidate. There are quite a few nurses who go on to medical school, and because of their prior experiences in the healthcare field, nurses tend to make excellent and empathetic doctors!
There are all different kinds of nursing. Basically every medical specialty will have an associated nursing specialty. You could be a pediatric nurse, a cardiac nurse, a labor & delivery nurse, a psychiatric nurse, an operating room nurse, an oncology nurse, a geriatric nurse, an orthopedic nurse, etc. Most nurses start off on a general medical unit to get a couple years of foundational experience, and then they move on to more specialized areas (though plenty of people go into their preferred specialty right out of school). People who have been nurses for decades have generally worked in a lot of different specialty areas. Nursing is very flexible in that way; if you get bored with the area you’re in, you can pretty easily switch to any other area.
Income varies depending on experience, just like any other job. A new nurse just starting out will probably make $35,000-$45,000/year, though nurses with a few years’ experience will probably make $50,000-$60,000/year. If you go back to school to get your Master’s (MSN), then you will be making $70,000-$90,000/year.
Nursing is probably the most competitive undergraduate degree you could possibly pursue. Because of all the hype in the media about the nursing shortage, tons and tons and tons and tons of people are applying for nursing school at the moment. It’s not unusual for there to be 500 applicants for a program that only has 75 open spots. You have to work really, really hard in all of your general education classes (e.g., Anatomy, Psychology) in order to be accepted.
Job competition used to not be a problem. The shortage was so bad that hospitals were throwing jobs at new graduate nurses, along with sign-on bonuses of several thousand dollars. Things are much different now though. Because of the economy, hospitals are instituting hiring freezes (and some are even firing staff nurses). I am graduating in May, and despite applying for many different RN positions, I have been turned down for all of them (not even being interviewed). Many of my classmates have also not been able to find jobs. The only people I know who have been able to find work are those who worked as student nurse externs (basically the same thing as a nursing assistant) during nursing school. Those people are just being hired on to the units they were already working on. However, this situation is likely to change with time. Once the economy starts to turn around, it’s most likely going to be fairly easy to find jobs again. If you are not even in nursing school yet, I wouldn’t worry about what’s going on at the moment. By the time you would be graduating, the economy will have recovered and you should have no problem finding a job.
Most units have 12-hour work schedules (usually 7 a.m. to 7 p.m. or 7 p.m. to 7 a.m.). Some places will have 8-hour shifts, but this is more and more uncommon. You will likely have to work one weekend a month, and you will probably have to work a major holiday (e.g., Christmas, Thanksgiving) at least once a year. The good part though is that you get paid much more (several dollars extra an hour) for working nights, weekends, and holidays.
