Answer to Question 1

B
Aged cheeses are rich in tyramine, which interacts with MAO inhibitors to raise blood pressure to life-threatening levels. Patients taking MAO inhibitors should be taught to avoid tyramine-rich foods. Chianti wine contains tyramine, but other alcoholic beverages do not. Brussels sprouts and cabbage are foods rich in vitamin K, which can interfere with the effects of warfarin. Grapefruit juice inhibits CYP3A4 and interferes with the metabolism of many medications.

Answer to Question 2

A
For patients with chronic, severe COPD, the risk of exacerbations may be reduced with roflumi-last. Theophylline is used only when other bronchodilators are not effective. Oral steroids are not indicated for this use. Ipratropium is used to treat bronchospasm in COPD.
