Which of the following actions should a nurse take after overhearing a breach of client confidentiality?

After overhearing a breach of client confidentiality, the appropriate action for the nurse to take is to report the incident to the hospital administration immediately. This course of action is crucial because client confidentiality is a fundamental aspect of nursing ethics and legal standards, specifically under laws like HIPAA (Health Insurance Portability and Accountability Act). Reporting the incident aligns with the responsibilities of a nurse to protect patient privacy and to ensure that any breaches are addressed properly by the institution.

By notifying the administration, the nurse ensures that the appropriate investigative actions can be taken. This is important not only for the protection of the affected patient but also for compliance with legal obligations and policies set forth by the healthcare facility. It demonstrates accountability and professionalism, and could potentially prevent further breaches of confidentiality.

The other options, while potentially well-intentioned, are not the most appropriate actions. Confronting the nurses involved could escalate the situation and may not lead to a constructive outcome. Planning an in-service program for the nurses may take time and does not address the immediate breach that has occurred. Ignoring the incident is not advisable, as it could allow harmful practices to continue without repercussions, further compromising patient safety and trust.
