In the United States, you cannot enter medical school with a nursing background.

However misinformed you may have been about nursing and medical school, I would like to clarify that I am disproving you at the moment and there are physicians that started out as nurses.
After months of reading comments and posts on all different topics, I finally registered to respond to this thread.
Fortunately, I am a product of nursing. I graduated in 2007 with my BSN and have worked strictly in cardiac ICUs and cardiac cath labs. My intentions and goals to attend medical school came after I began my career as a nurse. Unlike your predictable pre-med students, my undergraduate courses were without the standard courses to prepare for the MCAT. (However, my nursing courses and clinicals were far more demanding than your gen. bio and chem courses.) I prepared on my own for the MCAT while working over 40 hours/week and on call over 7 nights/month. Although, my score may not be at 35R, my experience has given me an advantage, for my interviews and medical career.
Now, there are a few schools that do not have course requirements, but require a competitive MCAT score and GPA. My question to the pre-med students, what does it matter when you become doctor if you can say that you took 2 semester of bio, chem, o.chem, and physics? It doesn't. It won't. You will not put your transcripts in a frame in your office, you will put your diploma and license.
Look at the big picture. Nursing will give the advantage to medications, treatments, procedures, insurance, etc. With my degree, I am able to interpret EKGs, run code blues, give sedation, assist with surgical procedures, and coronary stent placement. (just a few things that a pre-med students would NEVER have the ability to do with their degree). So, I say, be a nursing major.
There are many physicians (not medical students or residents) I have as friends, who admire the advantage I will have as a medical student and a doctor. Be reasonable people, 5 years contract when you sign up for nursing school? Really? It's a free country.
That's my spill. I know it's long, but somebody had to say it.
