I am a student nurse with experience in phlebotomy and as a CNA. If you are going into nursing school, I highly recommend working as a nursing assistant. You will learn a lot more fundamentals of nursing care as a CNA versus working in phlebotomy.ar 25, '09 by Markina21. Im am a licensed Cna and I just finished my phlebotomy class and im going to become a registered phlebotomist in two weeks. If your going to go back to school like I am you will find the physical labor of being a Cna very tiring mixed with school it can be done but it is extremely challenging.
