I've been a med surg nurse for 4 yrs and I interviewed for a ccu position and I got it. I'm nervous now because I feel like there is so much I don't know and I feel the only thing med surg has taught me is time management,pushing pills,and how to work under high stress lol. I'm starting to second guess myself and thinking about turning theposition down because it seems so overwhelming sigh. I guess my question is how can I better prepare myself for this transition?
