ADN/BSN to MSN

This is just a question that arose in my mind when thinking about my future nursing goals:

When you apply for a MSN program, does it matter if your RN degree is an associates or a bachelors?
Can an associates degree RN apply for a master's program without having to take "extra" classes to equate them with bachelor's degree nurses?

I would like to eventually get a master's in nursing, but this is far down the road as I am an LPN, and in an associates degree program to get my RN. I was just wondering if I should plan on doing some type of ADN-BSN program before applying to a masters program.

Also, how long do these master's programs generally take (full time)?
...and how long does it take thereafter to become a nurse practitioner or nurse anesthetist (full time)

Thank you for your time in answering... I've searched the internet for some answers but you know how the internet can be... full of ALL different answers (not to mention ads for online schools). I though this would be the best place to find some people who know what they are talking about.
There are ADN to MSN programs, but they all require varying amounts of bridge courses between the ADN and MSN (see Frontier Nursing University for an example).Most MSN programs do require a BSN or an RN with a Bachelor's in another area. Even if you're an RN with a non-nursing Bachelor's, many still require bridge courses.The time to completion will vary depending on your school and program. From my research, CRNA seems to take longer than FNP (1 or 2 extra semesters full-time). You can finish most full-time MSN programs in about 40-50 credits, which would be about 4 semesters of full-time at 12 hours per semester.Again, this depends on your specific program. Research the different programs in your area to compare the actual number of credits required. Also, pay attention to clinical hours. In my area, CRNA's have a LOT more clinical hours than FNP, which is why it takes so much longer.Good luck.

It also varies by specialty. Certain specialties require that you be bachelors prepared before entering the MSN program.
