Answer to Question 1

ANS: C
A firm, small, movable mass, approximately the size of an olive, is felt in the right upper quadrant in 70-90 of infants with pyloric stenosis. Pyloric stenosis is not associated with diarrhea, bile regurgitation, or ascites.

Answer to Question 2

ANS: A
Adenocarcinomas are more prevalent in males and are associated with cigarette smoking, obesity, and gastroesophageal reflux disease (GERD). Intestinal parasites, ingestion of salty foods, or the use of antacids does not lead to adenocarcinoma of the esophagus.
