Impervious is synonymous with which property?

Impervious is synonymous with which property?

• A. Breathable
• B. Waterproof
• C. Non-sterile
• D. Lightweight

Answer: (B)

Impervious means a material does not allow liquids to pass through, acting as a barrier against fluids. In surgical draping and prep, this is what provides a dry, protected sterile field by preventing blood and other fluids from penetrating the fabric. Breathable materials, on the other hand, allow moisture to pass, so they are not impervious. Non-sterile relates to sterility status, not barrier performance, and lightweight describes weight, not liquid resistance. Therefore, the property that matches impervious is waterproof.
