Question 1

Which method is considered the MOST effective for sterilizing heat-sensitive medical equipment that cannot withstand high temperatures, such as certain endoscopes?

Accepted Answer

C. Ethylene Oxide (EtO) gas sterilization — Autoclaving (steam sterilization) and boiling water are effective for heat-resistant items but damage heat-sensitive equipment. Ethylene Oxide (EtO) gas sterilization is a low-temperature sterilization method specifically used for heat and moisture-sensitive medical devices, making it the most appropriate choice. Chemical disinfection with 70% alcohol is a disinfectant, not a sterilant, meaning it does not kill all microorganisms, including bacterial spores.
