Which sterilization requirement is accurate for sterilizing tools in a dry heat oven?

The accurate sterilization requirement for sterilizing tools in a dry heat oven is 1 hour at 340°F. This method effectively kills bacteria, viruses, and spores, ensuring that tools are free from contamination.

Dry heat sterilization works by using high temperatures to denature proteins and oxidize cell components, which is why it requires longer exposure times compared to other methods like steam sterilization. The temperature of 340°F is optimal for achieving complete sterilization within the specified duration.

Other options do not reflect the proper parameters for dry heat sterilization. For example, the lower temperatures and shorter times listed in the other answers do not achieve the necessary conditions for sterilization in a dry heat oven, as they either lack sufficient time or temperature for effective microbial kill. This underscores the importance of using the correct settings to ensure tool safety and efficacy.
