Hi! i am new to the forum and excited to see a forum for IV therapy nurses. I am taking the CRNI exam next week and would like some words of wisdom from those who are veretans! I have been studying for about 3 months but still feel overwhelmed! I work on a "stick and run" IV Team where we place PICCs and difficult IVs. So there are quite a few of the core areas where I feel lacking! Any adivse you could offer would be helpful.
