Final answer:
The nurse should question the prescription for ranitidine.
Step-by-step explanation:
The nurse should question the prescription for ranitidine. Ranitidine is an H₂ blocker that decreases the amount of acid made in the stomach and is commonly used to treat ulcers. However, ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) like aspirin, can increase the risk of gastrointestinal ulcers and bleeds. Therefore, it is not advisable to administer ranitidine along with ibuprofen to a client with a history of peptic ulcer disease.
