Question

which of the following works by permeating the instrument wrappings in an autoclave?
o chemical use
o disinfection
o dry heat
o moist heat (steam)

Explanation:

An autoclave uses moist heat (steam) for sterilization. Steam can permeate instrument wrappings, reaching the instruments to kill microbes. Chemical use, dry heat, and disinfection (a process, not a heating method here) don't fit as steam in autoclaves permeates wrappings.

Answer:

O Moist heat (steam)
