Answer to Question 1

ANS: B
While calcium carbonate is most effective in neutralizing acid, a significant amount can be systemically absorbed and can cause acid rebound. The other antacids do not have significant systemic absorption.

Answer to Question 2

ANS: D
Maalox contains magnesium and carries a risk of hypermagnesemia, especially with decreased renal function. Older patients have an increased risk of poor renal function, so this patient should especially be evaluated for hypermagnesemia.
