Pain in the right upper quadrant may indicate which infection?

• A. Appendicitis
• B. Cholecystitis
• C. Hysterectomy complications
• D. Abdominal hernia

Answer: (B)

Pain in the right upper quadrant is typically associated with the liver, gallbladder, and biliary tree. Cholecystitis, which is the inflammation of the gallbladder, often presents with pain in this specific area due to its anatomical location. When a gallbladder becomes inflamed, it can cause significant discomfort, especially after meals that are high in fat, which stimulate the gallbladder to contract.

Additional symptoms often accompany cholecystitis, such as nausea, vomiting, fever, and possibly jaundice if a bile duct becomes obstructed. The other conditions listed may cause abdominal pain, but they do not typically localize to the right upper quadrant in the same way that cholecystitis does. For example, appendicitis usually causes pain in the right lower quadrant, while complications from a hysterectomy or an abdominal hernia may not be as specifically localized and can vary in presentation. Therefore, the characteristic pain associated with cholecystitis makes it the most likely infection indicated by pain in the right upper quadrant.
