Rationale: A. Nurse 3 was providing CPR at the family's request and following the client’s wishes regarding DNR status. There is no breach of confidentiality in this action. B. Nurse 2 left a computer logged in, which allowed another provider to access client information using the nurse’s active login. This is a breach of confidentiality because it allowed unauthorized access to protected health information (PHI). Nurses should always log off or lock computers when unattended. C. Nurse 1 disclosed information about a client admitted from the emergency department to another client, sharing details about their injury. This is a breach of confidentiality because the nurse shared private client information with someone not involved in the client’s care. D. Nurse 5 administered pre-operative medication and explained surgery details without ensuring the client’s questions were answered. While this is a consent and patient rights issue, it does not constitute a breach of confidentiality. E. Nurse 4 allowed a roommate to interpret medication instructions instead of using a professional interpreter. This is a violation of patient rights and informed consent, but it is not primarily a breach of confidentiality since the client’s information was communicated to someone already in the room with them, with consent implied.
