What is one of the three questions related to maintaining confidentiality?

The question, "Does this person need to know this information?" is one of the key considerations when maintaining confidentiality. This question helps professionals determine whether sharing specific information is necessary and appropriate for the situation. When working with sensitive or personal information, it's crucial to assess the need-to-know basis; only individuals who have a legitimate reason or responsibility related to that information should have access to it. This approach promotes respect for individuals' privacy and helps in building trust between clients and professionals.

In contrast, the other options do not align directly with the principle of maintaining confidentiality. While they may touch on aspects of information sharing or judgment, they do not emphasize the importance of determining who requires access to the information for purposes related to their role or responsibilities. Thus, the focus on necessity in knowing the information directly supports the ethical practice of confidentiality within professional relationships.
