Answer to Question 1

ANS: D
Proton pump inhibitors can enhance the effects of digoxin, so patients should be monitored for digoxin toxicity. Changing the dose of either medication is not indicated prior to obtaining lab results that are positive for digoxin toxicity.

Answer to Question 2

ANS: C
Patients taking histamine2 blockers can expect abdominal pain to decrease after 1 to 2 weeks of drug therapy. Cimetidine is not as potent as ranitidine and interacts with many medications through the cytochrome P450 system. Three hundred milligrams is the maximum dose.
