9. The correct answer is C. This patient likely has biliary dyskinesia. This patient may have peptic ulcer disease but gall bladder disease has not been ruled out. An abdominal series would not be helpful. There is nothing in the data to suggest pneumoperitoneum or bowel obstruction. A upper GI with small bowel follow through would be helpful only if a stricture was expected. An ERCP would not be helpful because if the patient had a common bile duct stone, the patient would have some abnormalities on her liver function tests.

3. D is the correct answer. This patient has pneumoperitoneum on the chest x ray. This is a surgical emergency. In general geriatric abdominal pain presenting the emergency department has a high mortality rate anyway, getting a general surgeon involved as soon as possible is the best management. A CT scan is a long procedure and will take at least 90 minutes to prepare for. Giving the patient pain and nausea medicine is a decent option but not the best option now. Until it is clear exactly where the perforation is at, a NG tube should probably not be inserted yet.

2. A is the correct answer. CA 19-9 is a tumor marker for pancreatic cancer. It is also used for gall bladder cancer, bile duct cancer and gastric cancer. CA-125 is used in ovarian cancer. Alpha Fetal Protein (AFP) is used in liver and germ cell cancers. CA 15-3 is in breast cancer.

1. The correct answer is B. This patient has a clinical picture consistent with Zollinger Ellison Syndrome. Somatostatin Receptor Scintigraphy is the single best imaging test for identifying this. CLO testing is a biopsy test done during endoscopy to screen for H. Pylori and this would not be helpful because the patient is H. Pylori negative. Prostaglandin levels have no correlation with the development of ulcers. Cyclic AMP has nothing to do with the development of ulcers. The only "cure" for Zollinger Ellison syndrome is if a gastrin secreting tumor can be found and be surgically removed.
