Question

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

Explanation:

Autoclaves use steam for sterilization. Overcrowding instruments means steam can't reach all surfaces (as space between items is needed for steam to circulate and penetrate). The first option is wrong (indicator tabs' function isn't related to crowding). The second is wrong (crowding would hinder, not enhance, steam penetration). The fourth is wrong (weight isn't the issue here).

Answer:

C. Steam is unable to penetrate or reach all surfaces (assuming the options are labeled A - D with A: The packages indicator tabs no longer work, B: Steam penetrates all packages too well, C: Steam is unable to penetrate or reach all surfaces, D: The instruments are too heavy for the autoclave)
