Final answer:
Ethical guidelines and workplace policies are key safeguards to avoid subordination of judgment by setting conduct standards and clear expectations for behavior in the workplace.
Step-by-step explanation:
Among the options provided, ethical guidelines and workplace policies are safeguards designed to avoid subordination of judgment. Ethical guidelines provide a code of conduct for individuals to follow, ensuring decision-making aligns with professional standards. Workplace policies are established by organizations to set clear expectations on behavior and procedures, which help staff avoid conflicts of interest and maintain integrity in their work. The Threats and Safeguards Framework can also be considered a tool used by professionals to assess risks to their professional judgment and apply appropriate safeguards, but this framework is not an option per se; rather, it's a conceptual approach. Mandatory rest periods may indirectly contribute to sound judgment by preventing fatigue, but they are typically not designed specifically for the purpose of safeguarding against the subordination of judgment.
