Answer to Question 1

B
Hypomagnesemia can be caused by diuresis. Diuretic use with heart failure often contributes to low serum magnesium levels.

Answer to Question 2

A
Initially, when there is reperfusion, ischemic chest pain ceases abruptly as blood flow is restored. Another reliable indicator of reperfusion is the appearance of various reperfusion dysrhythmias. Premature ventricular contractions, bradycardias, heart block, ventricular tachycardia, and (rarely) ventricular fibrillation may occur.
