Steam sterilization is best suited for which type of loads?

• A. Loads that cannot tolerate moisture
• B. Loads consisting of liquids
• C. Moisture-tolerant instruments
• D. Powders that are heat sensitive

Answer: (C)

Steam sterilization relies on moist heat to transfer energy quickly and to denature microbes. The moisture helps steam penetrate surfaces and reach all areas, so items that can withstand both heat and moisture respond best to this method. That’s why moisture-tolerant instruments are the ideal load for steam sterilization. Loads that cannot tolerate moisture, liquids, or powders that are heat sensitive would be damaged or sterilization would be ineffective, making them less suitable for this method.
