Which action should the nurse leader take to maintain confidentiality?

Maintaining client confidentiality is a fundamental legal and ethical obligation governed by HIPAA and professional nursing standards. Information about a client's diagnosis, treatment, and care may only be shared with members of the healthcare team who are directly involved in that client's care and have a legitimate need to know the information. Providing information to the healthcare team involved in care is therefore the only option that correctly upholds confidentiality while facilitating safe, coordinated treatment. Discussing a client's diagnosis with colleagues at lunch violates confidentiality because such conversations occur in public spaces with individuals who may not be involved in that client's care. Telling a client's spouse details about their treatment without the client's explicit permission is a HIPAA violation regardless of the relationship, unless the client has authorized disclosure. Allowing a visiting friend to read the medical chart is a serious breach of confidentiality; access to medical records is restricted to authorized individuals only. The principle of minimum necessary information applies — sharing only what is needed for care among involved providers protects the client's privacy and legal rights.
