In some states the authorities involved (the DA's office) inform the state board of nursing at the time charges are filed. It can take weeks, months and even years for the Board to take action against your license. Do you have a lawyer? Were the charges reduced or did you plea down? You can have your lawyer check to see if there has been any formal complaint against your license. If no formal complaint has been made and you are in a plea bargain - You could ask that as a condition of acceptance that no complaint be made. However I believe that in all US states Felonies must be reported to the board. If your charges involved alcohol your board could remand you into treatment even if your BAL was below the legal limit.
My advice:
Make an anonymous call to your board and find out what happens in your state when a nurse is accused of a crime. Make sure you ask about misdimeanors ve felonies. Ask what the state policy is about the accused responsibility in reporting to their employer and to the Board.
Chances are if you ignore this it will not just go away. I know of one nurse(LVN) who had two drunk driving convictions followed by 5 years of sobriety with no reoccurance. When she applied for her RN the background check picked them up and she started her RN career in probation for three years.
Hope this information helps -
Peace and Namaste
