A client with cholelithiasis is admitted with jaundice due to obstruction of the common bile duct. Which finding is most important for the nurse to report to the healthcare provider?

A. Bile stained emesis: Vomiting bile can occur in biliary obstruction and gallbladder disease. While concerning, it is not immediately life-threatening. Symptom management and monitoring are important, but it does not require the most urgent provider notification. B. Radiating, sharp pain in right shoulder: Referred pain to the shoulder is a common feature of gallbladder inflammation or obstruction due to diaphragmatic irritation. Although uncomfortable, it is expected in cholelithiasis and does not indicate a critical complication. C. Clay colored stool: Pale or clay-colored stool reflects a lack of bile reaching the intestines, which confirms obstruction of the bile duct. This is significant but expected in jaundice related to cholelithiasis and not an acute emergency. D. Distended, hard, and rigid abdomen: A rigid, board-like abdomen indicates possible peritonitis, perforation, or severe intra-abdominal infection. This is a life-threatening complication requiring immediate reporting and urgent intervention.
