Hi, enfermera 2B (like the moniker). I will offer this advice, and perhaps alternative advice.
It largely depends on what your goals are for nursing. If you wish to be an administrator and pursue a masters, then perhaps you should consider Masters in Health Administration. You mentioned you wanted to be an NP, but unsure what you want to do with that masters degree....clinical or administration? MHA will get you to administration without the hefty wait for nursing school.
IF you wish to really sink your teeth into the clinical aspects and are very sure that is the direction you wish to go, consider a PA program. PA (under normal circumstances) is masters level and will take you straight to the very heart of clinical, without having to get the BS, then MS in nursing. PA's (sorry NP's out there) also get (IMHO) more intensive clinical experience. Okay, now everyone, don't get on my case about this... Aside from neonatal and pediatric NP's, who are SO talented and focused (and usually help train med students and PA's), if you are working with adolescents-geriatrics, PA's get training in radiology AND cadaver gross anatomy, and nurses get
more theory. There are great NP's and sorry PA's, but over and over again I have seen PA's that are stunning diagnosticians and put many NP's to shame. Again...all the nurses out there who read this, please don't rag on me for not supporting NP's more. I started an NP program, but decided for many personal reasons not to continue (and it was not the challenge of the program-I graduated Summa Cum Laude with my BS and made A's while in the NP program). You may have to take some more pre-req's for the PA program (physics and math come to mind, depending on what you already have), but it is an option.
If you decide to pursue the BSN, then I would suggest that, are there any additional courses you can take that are normally a part of the program (have you taken nutrition? pathophysiology? is it possible to take an entry level pharmacology course? even organic chemistry..which usually is not required, but may help your transcripts look more appealing to the powers-that-be re: entrance to the program. I hope this helps.
