Answer to Question 1

ANS: A
A corticosteroid such as dexamethasone reduces inflammation and controls pain.

Answer to Question 2

ANS: B
A chlorine preparation, such as Dakin's solution, is used for infected wounds when other agents or methods are not effective or available. They dissolve necrotic materials and blood clots. A disadvantage is that they delay blood clotting, which can then interfere with wound healing.
