Employment at a hostpial with expunged misdemeanor?

[alexiscc]

Hello. I have a misdemeanor that was expunged. I asked a question on this board earlier asking about this, and I got a reply like "why do you even want to compete with those without criminal record in this market?". The thing is my misdemeanor was expunged and I don't have to answer "yes" to "Have you been convicted?". But what I wonder is: the arrest should still show up on finger prints card/check?--or does fingerprint card only address convictions, not arrests? In general, since my conviction shouldn't show on background check, would hospitals/nursing homes find out bout the arrest and initial charge?
