Answer to Question 1

ANS: A
The surface of the device should be disinfected using a 70 ethyl alcohol solution or the equiva-lent.

Answer to Question 2

ANS: C
Soaps act by lowering surface tension and forming an emulsion with organic matter. Unfortu-nately, soaps have little bactericidal activity and work poorly in hard water. A detergent refers to a substance (usually a chemical agent but sometimes a physical one) applied to inanimate objects that destroys disease-causing pathogens but not spores.
