Which statement about gown material and change interval is true?

• A. Gowns are cotton and changed every 2-3 hours
• B. Gowns are polyethylene coated polypropylene and changed every 2-3 hours
• C. Gowns are vinyl and changed every 24 hours
• D. Gowns are polyethylene coated polypropylene and changed every 12 hours

Answer: (B)

Handling hazardous drugs requires a gown that provides a strong barrier and is replaced regularly to prevent exposure. A polyethylene-coated polypropylene gown combines a durable base with a moisture- and chemical-impermeable layer, giving reliable protection against drug residues during preparation and administration. Changing this gown every 2 to 3 hours helps ensure the barrier remains effective, especially if the gown becomes damp, soiled, or after any exposure event. Cotton gowns absorb liquids and are not protective enough; vinyl or plain polypropylene can offer less reliable barrier performance for hazardous drugs. Longer intervals like 12 or 24 hours leave residues on the barrier too long, increasing the risk of permeation.
