Good answers posted here. My question to you is how were your grades in high school...and did you do well in the sciences, were you inclined to academics?
There is a lot of studying and learning involved in nursing programs...more basic for LPN, indepth for RN.....and the prereqs for RN can be difficult for someone who is not academically inclined....grades are required to be high for admittance to the upper level nursing courses, I hear. This was the same when I went through school 30 years ago.
I did LPN first and worked my way through RN school. I don't regret it, family needed the income. It is hard to work fulltime through RN school but many facilities will accomodate a student and even help with tuition reimbursement, in return for a period of employment following graduation.
If you like academics and can go to school 4 yrs (ie have hubby's income and savings to accomodate this ) and know you want the RN credential, consider a 4 yr degree (BSN) It affords you more opportunities to advance/move into other areas of nursing should you wish.
If you want bedside nursing a few years sooner, consider LPN (quicker) or ADN (RN pay, faster than BSN).
Best wishes to you in your quest...nursing is not for everyone but there ARE lots of options and a variety of opportunities out there.
