Answer to Question 1

ANS: C
Pancuronium bromide is used as a depolarizing muscle relaxant during anesthesia.

Answer to Question 2

ANS: A
COX-2 is an enzyme that converts arachidonic acid into prostaglandins and their products, and this synthesis causes pain and inflammation. They do not act directly to cause inflammation. COX-1 irritates the gastric mucosa. COX-2 synthesizes but does not release prostaglandins.
