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.

8. 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.
