The husband of a terminally ill woman called 9-1-1 because he thinks his wife is about to die. What should you do?

Providing emotional support and treating both the husband and his wife with respect is the most appropriate response in this situation. When dealing with a terminally ill patient, especially at the end of life, it is crucial to recognize the emotional distress that family members often experience. The husband is likely facing significant fear and uncertainty, believing that his wife is nearing death.

In this context, offering emotional support can help alleviate some of the stress and anxiety he is feeling. It’s also essential to acknowledge the dynamics of a DNR (Do Not Resuscitate) order; while the husband’s call indicates concern for his wife’s immediate health, respecting the wishes documented in a DNR order is paramount unless he clearly states otherwise.

The other choices might suggest a misunderstanding of the situation or could lead to unnecessary escalation. Asking why the husband called EMS may come off as dismissive of his feelings. Assuming the DNR is revoked without clear communication could lead to actions that don't align with the patient’s wishes. Additionally, contacting medical control could lead to delays in addressing immediate emotional needs, and the situation may not necessitate further medical intervention.

Thus, focusing on compassion and support in this critical moment is the most fitting response.
