Answer to Question 1

ANS: D
Pain is the cardinal feature. It is initially generalized, usually periumbilical. The pain localizes to the right lower quadrant at McBurney point. Rebound tenderness is not a reliable sign and is extremely painful to the child. Bright red or dark red rectal bleeding and abdominal pain that is relieved by eating are not signs of acute appendicitis.

Answer to Question 2

ANS: C
The mechanism of action of histamine-receptor antagonists is to reduce the amount of acid present in gastric contents and perhaps prevent esophagitis. Preventing reflux or hematemesis and increasing gastric acid production are not the modes of action of histamine-receptor antagonists.
