A nurse overhears two assistive personnel discussing a client's medical history in the hallway. Which of the following actions should the nurse take first?

a. While reporting the incident is important, the priority is to stop the confidentiality breach immediately to protect the client's privacy. b. Participating in training is important for long-term education, but it does not address the immediate issue of the confidentiality breach. c. Tell the staff members to stop their discussion: This action stops the breach immediately and protects the client's confidential information, which is the first and most crucial step. d. Speak to the staff members in private about client confidentiality: While this is a good follow-up action to educate and prevent future breaches, the immediate need is to stop the ongoing discussion
