Answer to Question 1

ANS: B
The temperature of the washer sterilizer ranges from 250 F to 280 F (121 C to 138 C).

Answer to Question 2

ANS: B
UV rays can cause burns similar to sunburns, and thus skin covering and protective goggles must be worn when exposed to them. Pathogens moving across the ray of UV light may not be exposed to radiant energy long enough for effective contact and destruction to occur.
