I have to chime in here...
I AM a nurse, BSN prepared. I am an ER nurse also. I would like to become a physician because of the number of acute patients I have seen that need a family doctor to follow their care for the rest of their lives. If I could do it as a BSN prepared person, I would. But I can't. I've gotten into the minds of many people who don't/didn't take their medications as prescribed because they didn't know enough about the medications, couldn't afford them, don't give a rip, whatever the reason is. THIS is why I want to become a physician.
Nursing is night and day to medicine. Nursing is nursing, not medicine. I worked with nurses who did NOT get that (and no wonder why docs couldn't stand them). Look up what Florence Nightengale believed and stood up for.
So...my advice to you is if you like the nursing model, do it. If you want to help the little old lady to the restroom after her surgery, measure out the urine (for your I's & O's) to ensure she's not having a neurogenic bladder, or respositioning her for improved comfort and circulation, do it (that's a med-surg nurse). Or if you like chasing the drunk dude running down the hall while he's ripping out your IV's at 2 a.m. do ED. If you want to write orders for pain PRN q4-6, nausea meds q4-6 PRN, vitals q8, etc, and see her for a follow up visit in 10 days to ensure all is well and continue to follow her, please be a doc. Again, nursing and doctor are two different animals.
You're very sweet and so young 🙂 Follow a nurse (ED is a good place to start because you'll see everything), follow a doctor (whatever you think you may like to do) and then see what fits. If you want to do both, give it time, work as a nurse and then go on.
