A nurse is preparing to administer medications and notices that two medications are to be administered at the same time: calcium carbonate (Tums)and ranitidine (Zantac).Which is the correct order to administer these medications?

Question

Quizplus · Accepted Answer

Ranitidine (Zantac) should be administered first because it is a histamine-2 blocker that reduces stomach acid, allowing for better absorption of calcium carbonate (Tums) when given later. Waiting 1 hour after administering ranitidine ensures that the medication has had sufficient time to reduce stomach acid levels before introducing calcium carbonate.
