False

true/false Gravity displacement steam sterilizer cycles are much shorter than prevacuum cycles.

true

true/false In steam sterilization, thermal destruction of microbes is the result of the denaturation and coagulation of protein within the cells.

true

true/false Internal chemical indicator/integrators should be placed in the center or most challenging portion of a tray for the sterilant to reach.

true

true/false Sterilization process monitors include mechanical, chemical, and biological methods to ensure all parameters were met.

False

true/false The relative humidity in an ethylene oxide sterilizer should be below 30% to aid in the penetration of the gas through bacterial spores' protective coating.
