NO!!! (is that emphatic enough?)
That would be a complete waste of your time and money - especially from an online school. I realize that it may be heavily marketed by online schools - who sell tuition, not education - but it would not have any value in terms of getting a job. Go ahead and begin working as a PCT, but if you're looking for a healthcare career, there are really no quickie online degrees that will get you where you want to be. Get a list of the pre-requisite classes you will need for nursing school and go ahead and start working on them. This will take you a while. Even if you change your mind or can't get into a nursing program, those classes will probably also be required for other types of healthcare careers.
