Answer to Question 1

ANS: C
Blood stools are often a presenting sign of Meckel's diverticulum. It is associated with mild-to-profuse intestinal bleeding. It is twice as common in males as in females, and complications are more frequent in males. Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract and is present in 1 to 4 of the general population. The standard therapy is surgical removal of the diverticulum.

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 may prevent esophagitis. Preventing reflux and hematemesis and increasing gastric acid production are not the modes of action of histamine receptor antagonists.
