Answer to Question 1

ANS: A
Formaldehyde will leave a residue on equipment. The other agents listed in these choices will not.

Answer to Question 2

ANS: D
High-level disinfectant agents are typically chemical sterilants that are used at reduced exposure times, usually less than 45 minutes. They kill bacteria, fungi, and viruses in this period of time. However, spores are not killed unless the chemical is used for an extended period of time.
