Monitoring & QA第 65 / 100 题
Where should the process challenge device be placed in a steam sterilizer chamber for routine biological monitoring?
a.On the top shelf at the rear of the chamber
b.In the geometric center of the load, surrounded by the densest packs
c.In the area identified as the most difficult for the sterilant to reach, typically on the bottom shelf near the front over the drain
d.Outside the chamber, taped to the sterilizer door
解析
Air is heaviest and settles low near the drain, so the front bottom of the chamber is the recognized cold spot for a steam sterilizer and is where the PCD is placed. Testing an easy location would give a falsely reassuring result. The exact placement follows the sterilizer manufacturer instructions, and an indicator outside the chamber tests nothing.
