Answer to Question 1

C
No adjustment of dosage is necessary for older patients taking PPIs. Patients with a history of renal disease may have decreased elimination of histamine-2 blockers, so the NP should avoid these if possible.

Answer to Question 2

C
If the patient does not start to see improvement within a few days after initiation of treatment with a histamine-2 blocker, the provider either should increase the dose of the medication or should change to a PPI. Cimetidine is a histamine-2 blocker and has many serious side effects. Metronidazole is used only when H. pylori is known to be present. Patients should start to get relief within a few days.
