Answer to Question 1

B
Because PPIs decrease gastric acid, they may interfere with the absorption of drugs that require absorption in an acid stomach, including digoxin. It may be necessary to increase the dose of digoxin but not before obtaining a serum digoxin level. All PPIs have this effect, so changing to another PPI would not solve the problem. Increasing the dose of lansoprazole would decrease the absorption of digoxin.

Answer to Question 2

A
Patients with congestive heart failure may have tachycardia from fever that aggravates their symptoms, so fever should be treated. High doses should be given with caution in elderly patients because of possible decreased hepatic function. Antibiotics should not be given without evidence of bacterial infection.
