Up to 60% of patients with a history of an upper GI bleed are bleeding from the same lesion. Ask the patient about medications. Non-steroidal anti-inflammatory drugs and acetylsalicylic acid can predispose the patient to peptic ulcer disease; antiplatelets and anticoagulants can promote bleeding; and bismuth and iron can cause stool to appear black. Liver cirrhosis can indicate varices. Aortic stenosis and renal disease can indicate angioectasia. Tobacco abuse, alcohol abuse, and Helicobacter pylori can indicate a malignancy.

Explanation: The correct answer is D. The patient has a duodenal peptic ulcer. The strongest risk factor for duodenal peptic ulcer is Helicobacter pylori infection, which is found in almost 100% of these cases (contrast to 70% infection rate in gastric peptic ulcer). The basal acid output is normal in many patients with duodenal ulcer. Aspirin use (choice A) and ethanol use (choice C) are more strongly implicated in gastric ulcer disease than duodenal ulcer disease. Chronic antacid use (choice B) is seen as a result of peptic ulcer disease, not as a cause of it.
