Answer to Question 1

D

Answer to Question 2

Some drugs are absorbed better in an acidic environment, whereas others are absorbed better under alkaline conditions. For example, reduced stomach acidity (due to secretory disorders or antacid medications) may reduce the absorption of ketoconazole (Nizoral, an antifungal medication) and atazanavir (an antiretroviral medication), but increase the absorption of digoxin (Lanoxin, which treats heart failure) and alendronate (Fosamax, which treats osteoporosis). Some drugs can be damaged by acid and are available in coated forms that resist the stomach's acidity.
