Answer to Question 1

C
Ulcers do not heal in an acidic environment. Histamine increases acid production by stimulating the stomach's parietal cells to secrete hydrochloric acid. Histamine (H2) blockers reduce the amount of histamine that is present, which then results in less stimulation of the parietal cells.

Answer to Question 2

C
Atazanavir can impair electrical conduction in the heart and lead to heart block, especially in older adults or people who have an abnormally slow heart rate.
