(b) The board may treat a person's acceptance of corrective or deferred action as an admission of a violation if the board imposes a sanction on the person for a subsequent violation of this chapter or a rule or order adopted under this chapter.
(c) The board may consider a corrective or deferred action taken against a person to be a prior disciplinary action under this chapter when imposing a sanction on the person for a subsequent violation of this chapter or a rule or order adopted under this chapter.
