Q: What is the role of a biological indicator in sterilization processes?
Solution:
Biological indicators are used to verify the effectiveness of sterilization by demonstrating that spores have been killed.
Steps: 5
Show Steps
Step 1: Understand that sterilization is a process used to kill all microorganisms, including bacteria and spores.
Step 2: Know that biological indicators are special tools used to check if the sterilization process worked.
Step 3: Realize that these indicators contain spores of a specific microorganism that are resistant to the sterilization process.
Step 4: After the sterilization process, the biological indicator is checked to see if the spores are alive or dead.
Step 5: If the spores are dead, it means the sterilization was effective. If they are alive, it means the process failed.
