Which of the following sterilizing agent used is sporicidal, antibacterial, antifungal and virucidal
**Core Concept**
The question is testing the knowledge of a sterilizing agent that possesses broad-spectrum antimicrobial activity, including sporicidal, antibacterial, antifungal, and virucidal properties. This agent is commonly used in healthcare settings to eliminate microorganisms from equipment and surfaces.
**Why the Correct Answer is Right**
The correct answer is Ethylene Oxide (EO). Ethylene oxide is a potent sterilizing agent that is effective against a wide range of microorganisms, including bacteria, viruses, fungi, and spores. It works by alkylating the DNA of microorganisms, thereby inhibiting their growth and replication. Ethylene oxide is commonly used to sterilize heat-sensitive medical devices, such as plastics, rubber, and textiles.
**Why Each Wrong Option is Incorrect**
**Option A:** Glutaraldehyde is a disinfectant and sterilant, but it is not sporicidal and can be toxic to humans and animals. It is commonly used to disinfect heat-sensitive equipment and surfaces.
**Option B:** Hydrogen Peroxide is a disinfectant and antiseptic, but it is not sporicidal and can be unstable and explosive in high concentrations. It is commonly used to disinfect surfaces and equipment.
**Option C:** Chlorhexidine is an antibacterial and antifungal agent, but it is not sporicidal and is not used as a sterilizing agent. It is commonly used to disinfect skin and mucous membranes.
**Clinical Pearl / High-Yield Fact**
When using ethylene oxide for sterilization, it is essential to ensure proper ventilation and follow strict guidelines to prevent exposure to toxic fumes. This is because ethylene oxide is a known carcinogen and can cause respiratory and neurological problems in humans.
**Correct Answer:** C. Ethylene Oxide
