Which of the following defines semi-critical items?

Semi-critical items are defined as those that come into contact with mucous membranes or non-intact skin but do not penetrate them. This classification is important in the context of infection control and disinfection practices. Such items must undergo high-level disinfection to ensure they are safe for use and do not pose a risk of transmission of pathogens. High-level disinfection is a process that eliminates a broad range of harmful microorganisms but may not guarantee complete sterilization.

Options involving contact with sterile tissue and intact skin refer to different categories of items. For instance, items that contact sterile tissue would require sterilization, not just disinfection, while items that only touch intact skin may require a lower level of disinfection, such as cleaning. Items that do not touch the client at all fall into a separate category altogether and therefore do not fall under the definition of semi-critical items. Understanding these distinctions helps ensure proper handling and preventive measures regarding infection control.
