I took my CNA course in high school and work in a hosptial in Med-Surg right now, and I like it a lot. I'm starting nursing school in January, and I've been told that it would help me a lot with nursing school cause I'd already be used to being in a hospital. I feel just like you. I just took a phlebotomy course (not completely done yet though, just have clinicals left to do!) to help me feel more comfortable sticking people in nursing school. I was told that phlebotomy is different from starting IVs, but the general knoweledge could only help you. If you have the time to do this course, I think it wouldn't be a bad idea, but I don't believe it's essential. Another reason I took a phlebotomy course was as a plan B in case I didn't get into nursing school right away. The decision is up to you though. Good luck! I also consulted with a professor in the nursing dpartment at my university about the idea, so that is something you could do also. It didn't help me get into nursing school because I wasn't done with it when I applied (it would have if I was done though, cause it's a certificate), but the CNA course and direct patient care that I do got me some extra points on my application. Good luck!
