Autoclave is/are used for sterilization of:
**Core Concept**
Autoclaving is a widely used method for sterilization, particularly in healthcare settings, that utilizes high-pressure steam to kill microorganisms. This process involves subjecting materials to a combination of temperature, pressure, and steam to achieve microbial inactivation.
**Why the Correct Answer is Right**
Autoclaving is effective against a broad spectrum of microorganisms, including bacteria, viruses, fungi, and spores. The process involves the use of a high-pressure steam generator, which produces steam at a temperature of 121°C (250°F) at 15 psi. This temperature and pressure combination is sufficient to penetrate the cell walls of microorganisms, leading to cellular disruption and death. Autoclaving is commonly used for sterilizing medical equipment, instruments, and supplies, as well as for cleaning and disinfecting surfaces.
**Why Each Wrong Option is Incorrect**
**Option A:** Glassware and equipment with narrow necks or crevices, which can trap steam and prevent effective sterilization.
**Option B:** Chemical disinfectants, which are not as effective as autoclaving for sterilizing equipment and supplies.
**Option C:** Dry heat sterilization, which is a different method that uses hot air to kill microorganisms.
**Clinical Pearl / High-Yield Fact**
Autoclaving is a reliable and efficient method for sterilization, but it's essential to ensure that the equipment is properly loaded, sealed, and maintained to prevent contamination and ensure effective sterilization.
**Correct Answer:** D. Equipment and supplies
