Final answer:
In this situation, you should prioritize patient confidentiality, while also encouraging the patient to inform their spouse about their HIV status.
Step-by-step explanation:
As a healthcare professional, it is your ethical responsibility to prioritize patient confidentiality and respect their privacy. In this situation, you should explain to the patient the importance of informing their sexual partner about their HIV status for the sake of their partner's health. However, you cannot disclose any personal information about the patient without their consent.
You can educate the patient about the potential risks of not notifying their partner and encourage them to have an open and honest conversation with their spouse. It is important to provide support and resources to help them navigate this difficult situation.
