Help again Cna Background check?

I was arrested for battery with domestic violence my mom had said i threw my cell phone at her... Charges were never pressed i never was convicted only arrested.. I have 6 months till i ship to basic Training at Ft jackson and to kill time i was taking a cna class im worried about the background check coming up and not being able to be licensed. can anyone let me know what the disqualifications are ? and if there is any way around it.. The ARMY pr emitted me to enlist with only a phone interview, but im assuming the florida state nursing board will not be as easy. thanks in advance for an help given :-)
