Hi. I was going to take the PCCN exam but chose the ANCC Med-surg exam. I used David Woodruff's material and did great. He also has a PCCN review. His material is worth the money. Very charismatic and great at explaining hard topics. I hope this helps.
I agree with all the above but love nursing for the holistic care. I love patient interaction. Medicine is very hands off and nurses are not. I am in NP school right now but have been a RN for 7 years. DO is a cool program though. I have never regretted becoming a RN. It is hard work but well worth it.
