Answer to Question 1

ANS: B
Glutaraldehyde is sporicidal and has an exposure time of 6 to 8 hours. Iodophors are bactericidal, tuberculocidal, fungicidal, and virucidal, but they are not effective against bacterial spores. Al-cohols are bactericidal, fungicidal, and virucidal, but they do not kill bacterial spores. Quaternary ammonium compounds are not sporicidal.

Answer to Question 2

ANS: B
Phenolic compounds are diluted to a 0.4 to 5 solution to provide a low to intermediate level of disinfection.
