Infection Prevention & Safety第 94 / 100 题
A technician wants to break the chain of infection during instrument reprocessing. Which action most directly interrupts the mode of transmission link?
a.Receiving the hepatitis B vaccination series
b.Reporting to occupational health after an exposure
c.Keeping the decontamination area under negative pressure
d.Performing hand hygiene and using containment during handling and transport of contaminated items
解析
Mode of transmission is the link describing how an organism moves from a reservoir to a new host, so hand hygiene and containment of soiled items during handling and transport target that link directly. Vaccination protects the susceptible host link. Post-exposure reporting is a response measure rather than a chain interruption, and negative pressure primarily controls the environmental reservoir and airborne spread within the room.
