Hello, I was wondering if RaginCajunRN is from Lafayette? I graduated from ULL in the fall of 2002. I will be attending TCU in August. If the message applies to TCU, I had no questions on the balloon pump. However, studying for CCRN is very essential for the program. It is now a requirement. It will increase your confidence and overall view of critical care. Study hard and do practice questions. The test is hard but passable. Talk to you soon. micvic RN,BSN,CCRN,SRNA
