What is the final cycle temperature of a washer-sterilizer?

• A. 250°F
• B. 270°F
• C. 290°F
• D. 310°F

Answer: (C)

The final cycle temperature of a washer-sterilizer is 270°F. This temperature is essential for effectively denaturing proteins and ensuring the destruction of microbial life, including spores. Washer-sterilizers are designed to not only clean but also to deliver high-level disinfection or sterilization, making this temperature critical for achieving the desired level of microbial reduction.

At 270°F, the conditions within the washer-sterilizer provide a combination of heat and moisture that promotes effective sterilization. This temperature also contributes to the integrity of most surgical instruments and medical devices, ensuring they remain functional after processing.

Understanding the importance of this temperature helps in maintaining compliance with infection control standards in healthcare settings. While there may be misinterpretations regarding higher temperatures, they can potentially damage heat-sensitive instruments and do not align with standard practices established for washer-sterilizers.
