Identify a common method for handling instruments that cannot be immersed in liquid.

Using surface disinfectants or barriers designed for those instruments is a common and effective method for handling items that cannot be immersed in liquid. Certain instruments, especially those with electronic components or delicate parts, can be damaged by immersion in fluids. In such cases, applying a suitable surface disinfectant can effectively eliminate pathogens while protecting the integrity of the instrument.

Additionally, using barriers, such as plastic wrap or specific covers designed for medical instruments, provides a way to maintain sterility during procedures without the need for immersion. This method is crucial in infection prevention, as it allows for the safe use of delicate instruments while adhering to infection control protocols.

The other options do not address the need for maintaining the integrity of instruments that cannot be immersed while ensuring they are adequately disinfected. Thus, utilizing surface disinfectants or protective barriers stands out as the most appropriate approach.
