During an appointment with his psychiatric-mental health nurse practitioner (PMHNP), a 35-year-old man makes a credible threat to murder the ex-husband of his girlfriend. Of the following, what should the PMHNP do?

Choice A reason: When a patient makes a credible threat of serious harm to an identifiable individual, the PMHNP has a duty to warn and protect. This includes notifying law enforcement to prevent potential violence. This action is supported by legal precedents such as the Tarasoff ruling and aligns with ethical obligations to protect third parties. Choice B reason: While warning the potential victim may seem appropriate, it is not the most secure or legally sound method. Law enforcement is better equipped to assess and manage threats, and direct contact with the victim may pose risks or violate procedural safeguards. Choice C reason: Indirectly warning the victim through a third party is unreliable and may delay intervention. It also risks breaching confidentiality without ensuring the threat is properly addressed. Choice D reason: Doing nothing in the face of a credible threat violates both ethical and legal responsibilities. Confidentiality has limits, especially when public safety is at risk.
