Question

multiple choice question why does overcrowding of instruments in an autoclave affect sterilization? steam is unable to penetrate or reach all surfaces the instruments are too heavy for the autoclave the packages indicator tabs no longer work steam penetrates all packages too well

Explanation:

Autoclaves use steam for sterilization. Overcrowding instruments means steam can't reach all surfaces (as steam needs to penetrate to sterilize). The "too heavy" option is irrelevant, indicator tabs aren't affected by crowding, and steam penetrating "too well" doesn't make sense for why sterilization is affected (it should penetrate adequately). So the correct reason is steam can't reach all surfaces.

Answer:

A. Steam is unable to penetrate or reach all surfaces
