Bacterial spores can be inactivated by exposure to:
a. 10 hours of iodophors.
b. 8 hours of glutaraldehyde.
c. 30 minutes of isopropyl alcohol.
d. 6 hours of quaternary ammonium com-pounds.
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.
