Which method is used to decontaminate a lancet after aiding in comedone extraction?

1. Soak in bleach

2. Heat in an autoclave

3. Wash in soap and water

4. Store in alcohol

The correct answer is: Heat in an autoclave

Using heat in an autoclave is the most effective and appropriate method for decontaminating a lancet after comedone extraction. The autoclave works by applying high pressure and temperature to sterilize instruments, effectively killing a wide range of pathogens, including bacteria, viruses, and fungi. This method ensures that the lancet is free from any infectious microorganisms, making it safe for future use. While other methods, such as soaking in bleach or using alcohol, may have some disinfecting properties, they do not achieve the same level of sterilization that an autoclave provides. Soaking in bleach might not be practical for instruments, as it can be corrosive and may not penetrate all areas of the device. Washing in soap and water can remove debris but does not guarantee sterilization. Storing in alcohol does provide disinfection, but it is not a substitute for the thorough sterilization process that the autoclave offers. Thus, utilizing an autoclave for decontamination is the gold standard in ensuring that the instrument is properly sanitized.
