The nurse is caring for a client with a new diagnosis of hyperthyroidism. Which intervention should the nurse prioritize?

Choice A reason: Rebound tenderness in the right lower quadrant (McBurney’s point) is a hallmark of appendicitis, indicating peritoneal irritation from an inflamed appendix. This localized pain, elicited on palpation release, is highly specific, guiding urgent surgical evaluation to prevent rupture and peritonitis.

Choice B reason: Diffuse abdominal pain is nonspecific and occurs in various conditions, not uniquely appendicitis, which typically presents with localized right lower quadrant pain. Rebound tenderness is more diagnostic, as it directly reflects appendiceal inflammation, making it the priority finding.

Choice C reason: Decreased bowel sounds may occur in appendicitis due to ileus but are nonspecific, seen in other abdominal conditions. Rebound tenderness is more indicative, as it localizes to the appendix, confirming peritoneal irritation, critical for diagnosing acute appendicitis.

Choice D reason: Elevated blood pressure is not specific to appendicitis and may reflect pain or stress. Rebound tenderness directly indicates appendiceal inflammation, making it the most reliable finding, as it guides diagnosis and urgent intervention to prevent complications like perforation.

Choice A reason: Hepatorenal failure involves liver and kidney dysfunction, typically from chronic liver disease or shock. Elevated amylase and lipase, with pain and vomiting, point to pancreatic inflammation, not hepatorenal issues. Pancreatitis is more consistent with the client’s post-cholecystectomy presentation and lab findings.

Choice B reason: Biliary duct obstruction causes jaundice and elevated bilirubin, not amylase or lipase. Pain may radiate, but vomiting and fever with high pancreatic enzymes suggest pancreatitis, a known post-cholecystectomy complication, rather than a blocked bile duct, which lacks pancreatic enzyme elevation.

Choice C reason: Surgical site infection causes localized pain, erythema, and fever but not elevated amylase or lipase. Radiating pain and vomiting align with pancreatitis, not wound infection. Pancreatic enzyme elevation is specific to pancreatic inflammation, making infection less likely than pancreatitis in this scenario.

Choice D reason: Acute pancreatitis is characterized by elevated amylase and lipase, epigastric pain radiating to the back, vomiting, and fever. Post-cholecystectomy, bile duct manipulation or gallstone migration can trigger pancreatitis. These findings align perfectly with the client’s symptoms and lab results, making it the correct condition.
