He also gives a history of nausea and vomiting for the past 8 hours. On examination, his temperature is 102F and he has right lower quadrant tenderness at McBurney’s Point.  CT scan of the abdomen revealed calcified appendicolith within the dilated, fluid-filled appendix and infiltration of the surrounding retroperitoneal fat. The patient is scheduled for Appendicectomy. However, pre-operative labs reveal an abnormal result that would put the patient at an increased risk of bleeding from surgery.
