In my neck of the woods, we don't even have PCTs, as the majority of what they would do is done by CNAs, then other responsibilities are divided between other staff (phlebotomy by lab, etc.).
I can't speak to the idea of the amount of money, but I do know that when I took the CNA class as a pre-req for my nursing program, I only paid for the three credit hour course (about $360) and the uniform (one set of scrubs only for clinical day) and then the exam. All in all, I was out about $500, at most!
I currrently work in a doctor's office, and make about $10.00, which is actually high for my area, but I also assist in medical billing, hence the "extra."
I had a friend that wanted to become an MD, but she thought that becoming a PA would be a good way to get "in..." So, I simply informed her of the difference, and the fact that the schools and exams are completely different! It was a hard thing for me to get across from her. It's not like becoming a CNA and working as one through nursing school!!!
Anyway, just be up front and honest with her, and if need be, try to get a meeting scheduled with your advisor (or a member of nursing staff) so that your friend can hear it from someone that undoubtly knows the difference between a PCT and an RN.
I have a quick question, though, does the program have her learning how to give meds, admin IVs, do tube feedings, etc.? If you ask her those questions, and she says no, maybe she'll get it!
Good luck :)
