Hazardous Drug Management Practice Test

Gowns used when handling hazardous drugs must provide a true liquid barrier to prevent permeation of cytotoxic agents. Polyethylene-coated polypropylene delivers that barrier: the sturdy polypropylene fabric is laminated with a thin polyethylene film, creating a surface that resists penetration by liquids and drug solutions while remaining disposable and relatively comfortable for use during preparation and administration. Cotton would absorb spills and can harbor contamination, increasing exposure risk. Non-woven polyester by itself does not guarantee a reliable liquid barrier unless it’s coated or laminated with a barrier film. While polyurethane can provide impermeability, chemotherapy gowns are typically made from polyethylene-coated polypropylene because it offers strong liquid barrier protection, durability, and cost-effective disposability.
