Correct Answer is B

Explanation

A. Nausea: Nausea can occur with peptic ulcers, particularly if gastric emptying is delayed or if inflammation affects the stomach lining. However, it is not the most common or defining symptom.

B. Pain in the epigastric region: Epigastric pain is the hallmark symptom of peptic ulcers. It is typically described as burning or gnawing and may occur between meals or at night, often relieved by eating or antacids.

C. Melena: Melena, or black tarry stools, can occur if the ulcer bleeds, but this is more of a complication than a routine symptom. It indicates gastrointestinal bleeding and requires urgent evaluation.

D. Decreased appetite: Appetite changes may occur, especially if eating exacerbates pain in gastric ulcers. However, decreased appetite is not as frequent or specific a symptom as epigastric pain.

A. Gallstones cholangitis: stones in the common bile duct = cholelithiasis; inflammation of the common bile duct-cholecystitis; inflammation of the gall bladder-choledocholithiasis B. Gall stones = cholangitis; stones in the common bile duct = cholecystitis; inflammation of the common bile duct = choledocholitiasis; inflammation of the gall bladder cholelithiasis C. Gallstones = cholelithiasis: stones in the common bile duct = cholecystitis; inflammation of the common bile duct = choledocholithiasis; inflammation of the gall bladder cholangitis D. Gall stones = cholelithiasis; stones in the common bile duct-cholelithiasis; inflammation of the common bile duct = cholangitis; inflammation of the gall bladder - cholecystitis

Correct Answer is D

Explanation

A. This option incorrectly matches the terms: cholelithiasis refers to gallstones, not stones in the common bile duct; cholecystitis is inflammation of the gallbladder, not the common bile duct; choledocholithiasis refers to stones in the common bile duct, not inflammation.

B. This option reverses definitions: cholangitis is inflammation of the common bile duct, not gallstones; cholecystitis is inflammation of the gallbladder, not stones in the common bile duct; choledocholithiasis refers to stones in the common bile duct, not inflammation.

C. This option mislabels choledocholithiasis as inflammation of the common bile duct, but it actually refers to stones in the common bile duct; cholecystitis is inflammation of the gallbladder, not stones in the common bile duct; cholangitis is inflammation of the common bile duct, not the gallbladder.

D. This option correctly matches the terms: cholelithiasis means gallstones; choledocholithiasis refers to stones in the common bile duct; cholangitis is inflammation of the common bile duct; cholecystitis is inflammation of the gallbladder.
