Gave the wrong breastmilk to infant, reprimanded and afraid I may lose current job

Hello Beth,  Three years ago I made a terrible mistake of giving the wrong breastmilk to an infant in the NICU. This incident happened in Nevada. I was disciplined by the Nevada BON.  I am now working in California and had to self report to the California BON. When I accepted job in California I didn't realize I was under investigation with the Nevada BON. I haven't told my current employer about the reprimand I received from the BON. Will I lose my job when I tell my employer about the reprimand?
