A 56-year-old man is admitted to the hospital because of a 1-day history of acute, severe, cramping abdominal pain that radiated to his back. The pain was constant and exacerbated when he tried to eat some food. The patient attempted to self medicate with acetaminophen, but with no relief. The pain has slowly worsened and he has not had anything to eat or drink in over a day. On admission to the hospital, his serum amylase and lipase levels are elevated. The appropriate therapy is initiated and the patient has improvement in his pain. He is also started on a morphine patient-controlled anesthetic (PCA) with excellent results. Over the next 24 hours, he remains stable. A follow-up set of blood chemistries shows a BUN of 26 mg/dL and a creatinine of 1.0 mg/dL with an unchanged amylase and lipase. A right upper quadrant ultrasound shows gallstones with no ductal dilation. The patient's other medications, besides the PCA, are diazepam for sleep and diphenhydramine.

B. arrange for hepatobiliary iminodiacetic acid scan
C. arrange for laparoscopic cholecystectomy
D. arrange for an open cholecystectomy
E. continue intravenous hydration and nil per os status
