Final answer:
The priority action is to interrupt the conversation and remind staff about privacy rights.
Step-by-step explanation:
The priority action that the per diem nurse should take in this situation is to interrupt the conversation and remind staff about privacy rights.
HIPAA, the Health Insurance Portability and Accountability Act, mandates patient privacy and protects their personal health information. It is the responsibility of healthcare professionals to ensure that patient information is kept confidential and not disclosed in public areas where unauthorized individuals can overhear.
By interrupting the conversation and reminding the staff about privacy rights, the nurse can help maintain patient confidentiality and prevent any further breaches of privacy.
