This good thinking! The most important clues was the risk factors, not the presentation... beside one only said PUD... could be either gastric or duodenal...If I remember, Gastric is associated with weight loss, because of fear of eating, pain is worst with eating. In Duodenal pain is less with food, but worst 30-40 minutes after eating... kind of like the question.
Regarding PUD, I found a nice pneumonic for indications for surgery
I; Intractable pain( not relieved by meds)
H;hemorrhage( most common reason for massive GI bleedind in Adult)
O;Obstruction from scarring
P; perforation.
