What type of devices require sterilization due to their exposure to nonintact skin?

• A. Non-critical devices
• B. Semi-critical devices
• C. Critical devices
• D. Disposable devices

Answer: (B)

Semi-critical devices require sterilization because they come into contact with nonintact skin or mucous membranes. These devices are often used in procedures where they may be exposed to blood or other bodily fluids, increasing the risk of infection if not properly sterilized. It is crucial to maintain a high standard of asepsis with these types of instruments to prevent the transmission of pathogens.

In contrast, critical devices typically enter sterile tissue or the vascular system and must be sterilized as well, but the key focus of the question is on exposure to nonintact skin, which consistently aligns with the definition of semi-critical devices. Non-critical devices, on the other hand, only come into contact with intact skin and do not require sterilization; instead, they may undergo cleaning or disinfection. Disposable devices are designed for single use and are discarded after one use but do not specifically relate to the sterilization requirement in the context of exposure to nonintact skin.
