Answer 1

1.   Choice B is the correct answer.  CT scan of the abdomen an pelvis is the imaging study of choice. This study has the highest yield.  Abdominal ultrasound can be attempted but often the appendix is not visualized especially if their is a lot of bowel gas.  Intravenous Pyelogram is for kidney stones.  A three view abdomen is useful when their is a suspicion of a bowel obstruction or perforation.  Air fluid levels would be seen in the case of a bowel obstruction on the upright films and pneumoperitoneum would be seen in the case of perforation.
