Explanation / Answer

Question: 29. Ethylene oxide is: O sporicidal only effective with high heat . the active agent in household bleach. O used as an antiseptic against anaerobes O a halogen.

Answer: Sporicidal

Ethylene oxide is a sporicidal fumigant. It is used for gaseous sterilization. It is active against spores. It is active against almost all types of microorganisms such as bacteria, and viruses. It has bactericidal, fungicidal, and virucidal properties.

Question: 30. All of the following are phenols or phenolics, except: O Lysol. 0 Hexachlorophene. O Triclosan O Cresols Chloramines.

Answer: Chloramines

Cresol and lysol are phenol derivatives. Hexachlorophene and triclosan are bis-phenols, complex phenolic compounds. Chloramines are derivatives of ammonia, chloramine reacts with phenol and form chlorophenols.

Question: 31. Physical agents for controlling microbial growth include all of the following, except: O ultraviolet radiation, O boiling water, O HEPA filters, O pasteurization, O hydrogen peroxide.

Answer: Hydrogen peroxide

Hydrogen peroxide is a chemical disinfecting agent used to control Microorganisms.

Question: 32. Which is mismatched? O Sodium hypochlorite-chlorine, O lodophor-iodine, O Benzalkonium chloride-quaternary ammonium compound, O Merthiolate - silver, O Formalin - formaldehyde.

Answer: Merthiolate - silver

Mercury is used as a component merthiolate. Silver is used as silver nitrate.
