SterilizationQuestion 34 of 100
After a tray fails its internal chemical indicator, the supervisor reviews the fundamentals with the team. Which four parameters must all be satisfied for steam sterilization to be effective?
a.Pressure, humidity, load weight, and cycle number
b.Time, temperature, moisture in the form of saturated steam, and direct contact with all surfaces
c.Vacuum depth, drying time, cooling time, and package integrity
d.Detergent, water quality, temperature, and packaging material
Explanation
Steam sterilization depends on saturated steam reaching every surface at the required temperature for the required time, which is why cleaning, correct packaging, and proper loading matter so much. Pressure is only the means of achieving the temperature, not an independent parameter. Drying, cooling, and cleaning variables affect the outcome and package integrity but are not the four critical parameters of the sterilization process itself.
