Correct answer: C

Where steam steriliser equipment failures have led to non-conforming items, the steriliser that has undergone a major repair needs to have full PQ performed to verify it is suitable to be returned to service (ICG p.54)

Remy's study tip — The differentiator is usually the Spaulding classification level or the step order in a protocol.
