- G.
Inactivates some viruses
- H.
Inactivates most viruses
- I.
Inactivates some/most fungi
Correct Answer(s)
A. Low-level disinfectants
E. Inactivates most bacteria except spores and resistant types

A certain theoretical chemical, chemical X, does not kill bacteria but does inhibit their growth. This chemical is also able to destroy viruses. This chemical would be considered:I. bactericidalII. bacteriostatic III. virucidalIV. disinfectant
- A.
I and II
- B.
I and III
- C.
II and III
- D.
II, III, and IV
- E.
I, II, III, and IV
Correct Answer
C. II and IIIExplanation
Obviously this is theoretical because anything that will kill a virus will probably kill bacteria, but I digress. Chemical X would be bacteriostatic (stops bacterial growth), virucidal (kills viruses), but would not be either bactericidal (kills bacteria) or a true disinfectant(kills some, most, or all bacteria) since it specified it "does not kill bacteria".Rate this question:
