Which statement about high level disinfectants is true?

• A. High level disinfectants are used to disinfect only disposable medical equipment.
• B. High level disinfectants sterilize all equipment.
• C. High level disinfectants are used to disinfect only reusable medical equipment.
• D. High level disinfectants are never used in healthcare settings.

Answer: (C)

High-level disinfection is used for reusable, heat‑sensitive medical equipment that comes into contact with mucous membranes or non‑intact skin after proper cleaning. This step aims to inactivate most pathogens on devices that cannot be sterilized by heat, without trying to achieve complete sterility for every item. That’s why the statement that best describes their use is that they are used to disinfect reusable medical equipment. Disposable items are single-use and aren’t subjected to disinfection, sterilization is a separate, more stringent process for items that require it, and high-level disinfection is not the same as sterilization for all equipment. In healthcare settings, high‑level disinfection plays a crucial role for reusable devices that can’t be heat‑sterilized, ensuring patient safety between uses.
