Glassware and syringes are sterilized by:
**Core Concept**
The sterilization of glassware and syringes is crucial in aseptic medical procedures to prevent contamination and ensure patient safety. This process involves the use of chemical agents that can effectively kill or inactivate microorganisms.
**Why the Correct Answer is Right**
The correct answer is autoclaving, which involves exposing the glassware and syringes to high-pressure steam. This process uses the heat and moisture to denature proteins, disrupt cell membranes, and ultimately kill bacterial spores. Autoclaving is a reliable method for sterilizing heat-stable materials, including glassware and syringes. This process is particularly effective against Clostridium difficile and other spore-forming bacteria.
**Why Each Wrong Option is Incorrect**
**Option A:** Ethylene oxide is a sterilizing agent, but it is typically used for heat-sensitive materials, not glassware and syringes.
**Option B:** Gamma radiation is another method of sterilization, but it is not commonly used for glassware and syringes due to the potential for radiation damage.
**Option C:** Dry heat sterilization is not effective for glassware and syringes, as the heat does not penetrate evenly and may not reach the required temperature to kill all microorganisms.
**Clinical Pearl / High-Yield Fact**
Autoclaving is not effective for sterilizing materials that are sensitive to heat or moisture, such as plastics, rubber, and some types of filters. Always check the manufacturer's recommendations for sterilization methods.
**Correct Answer:** C. Autoclaving
