Go straight for your BSN, you will have skipped over many things that will have wasted your time. For example; my nursing program (ADN) does not incorporate the pre-req's (anatomy, psych, microbiology etc) And most students take AT MINIMUM, one year to complete (usually 1.5 years which turns to 2 years because the program starts in fall. So you spend this one year taking pre-req's, and then two years of nursing to get an associates degree. If my math is correct, that is 3 years for a 2 yr degree, one more year would have equaled a BSN.
LVN is something you could do if you wanted, however you do not want to be stuck as a LVN in the long run (not bashing LVN's here, but if you want to be an RN, you don't want to be stuck as a LVN). This alone can be extremely difficult. A little research will tell you the struggles of part time / full time workers attending nursing school.
Then you'll probably be working as an LVN, and going to school for your ASN/BSN.
Keep in mind the hoops you must jump through for admission into each program, and which would be best / least stressful.
