The priority question for the nurse to ask this patient is 'What foods and drinks have you consumed today?' Facial flushing, a pounding headache, and high blood pressure can be signs of a hypertensive crisis caused by consuming tyramine while taking an MAOI anti-depressant.

Step-by-step explanation:
The priority question for the nurse to ask this patient is 'What foods and drinks have you consumed today?'
Facial flushing, a pounding headache, and high blood pressure can be signs of a hypertensive crisis, which can occur when a patient taking an MAOI anti-depressant consumes foods or drinks that contain tyramine. Tyramine is found in certain foods and beverages and can cause a sudden increase in blood pressure. By asking about the patient's diet, the nurse can determine if the symptoms are related to tyramine consumption and provide appropriate treatment.
