Regarding spore testing for autoclave sterilization — which frequency is an EXCEPTION (not required)?
Show answer and explanation
Correct answer: A. Monthly
✓ A) Monthly is the EXCEPTION — not the required minimum frequency.
CDC and OSAP guidelines recommend spore testing (biological indicators, e.g., Geobacillus stearothermophilus) at minimum WEEKLY — not merely monthly. Monthly testing is insufficient. Spore tests should also be performed: with each implantable device load, when a new sterilizer is installed, after sterilizer repair, and when sterilization protocol changes. Weekly is the minimum standard; many offices test with every load using chemical/process indicators as well.
