Which of the following is NOT a characteristic of disposable surgical gowns and drapes?

The assertion that recommendations against the use of disposable surgical gowns and drapes exist in general patient-care areas is not a characteristic of these items. Disposable surgical gowns and drapes are specifically designed for use in controlled environments such as operating rooms to provide a barrier against infectious agents. In general patient-care areas, the use of such gowns and drapes is not typically called into question, as they serve an important function in maintaining hygiene and preventing the spread of infection.

The other characteristics highlighted are fundamental to the usage of surgical gowns and drapes. They must indeed be resistant to liquid and microbial penetration to ensure that healthcare professionals and patients are protected during procedures. They also need to be registered with the FDA to guarantee that they meet necessary safety standards. Additionally, pore size is a crucial factor in gown performance, as it directly impacts the level of protection provided against microorganisms. Each of these characteristics emphasizes the importance of safety and effectiveness in sterile settings.
