Med-surg experience can help, yes. However, if you're not interested in med-surg I think it will turn out to be a nightmare for you. Don't do it just because you think you SHOULD. Choose your own path and if you come across a PP or ICU preceptorship, go for it. Do what YOU want. Plain and simple.
The last thing you want in your life is to find yourself in a job you hate. Maybe you don't hate med-surg...if you don't, do consider it. It WILL give you experience. But...if you're really really really interested in one of the other areas, you might want to try to get a job in that area. With the nursing shortage you have a lot of options and many areas of nursing are offering new-grad programs.
I started working in a level III NICU right out of nursing school
. I'm still there a year later and they'll have to drag me away from my babies kicking and screaming. I love where I work.
Basically, do what YOU want, and DON'T get a job in an area you hate!
