*sigh* I'll ignore the PE exam comment. I did sign an agreement not to disclose specifics of the exam, and I did my best to stick to that. I gave the biggest hints and tips I could within that agreement.
It occurred to me that perhaps you don't have access to uptodate. Someone reminded me that some hospitals are dumping their subscription due to high expense - something like $50+K/yr for a hospital.
I checked B&W, and sure enough it doesn't say anything about medical management for perforated ulcer. I didn't check Pocket Medicine. Tarascon Internal Medicine has specific criteria to rank risk for PUD and suggests medical management for those with adequate scores. However, keep in mind that on the COMLEX, generally the best answer will be the cheapest, least invasive.
In the case of perforated ulcer, medical management consisting of IV fluids, NG suction, ABX, and something like a PPI can lead to quickly healing perfed ulcers. Some hospitals use sucralfate as well. Such conservative medical management can lead to a 60-70% reduction in surgery for perforated ulcers, but at a cost of a slightly longer hospital stay. For an unspecified reasons, patients over 70yo did not respond quite as well to medical management as those under 70yo.
