Final answer:
An MRT must report observed sexual misconduct by a regulated professional to the CMRITO; it is a duty to ensure patient safety and professional integrity. Media and social media are inappropriate channels for such reports.
Step-by-step explanation:
If an Medical Radiation Technologist (MRT) observes sexual misconduct by any regulated professional, the correct action is to report the incident directly to the College of Medical Radiation and Imaging Technologists of Ontario (CMRITO), not to ignore the incident or spread the information via the media or social media platforms.
It is a professional responsibility to maintain patient safety and uphold the integrity of the profession. Therefore, the answer to the question is (a) Report to the CMRITO.
