The board may not take disciplinary action against an advanced practice registered nurse based solely on the advanced practice registered nurse prescribing or dispensing ivermectin for the off-label treatment or prevention of severe acute respiratory syndrome coronavirus 2 identified as SARS-CoV-2, or any mutation or viral fragments of SARS-CoV-2. This section does not limit the board from taking a disciplinary action on another basis, such as unlicensed    practice, inappropriate documentation, or substandard care, or any basis that would in the board’s determination harm the patient.
