Infection ControlQuestion 73 of 100
Which procedure correctly describes disinfecting an uncovered clinical contact surface between patients?
a.Spray the disinfectant and wipe immediately, then move on
b.Wipe with a dry paper towel and then spray
c.Clean the surface first to remove bioburden, then apply the disinfectant and allow the full manufacturer's contact time
d.Apply the disinfectant and wipe it off before it can dry
Explanation
Surfaces must first be cleaned to remove bioburden, then treated with disinfectant that remains wet for the full contact time listed by the manufacturer, which is often several minutes. Spraying and wiping immediately removes the product before it can kill microorganisms. Wiping with a dry towel spreads contamination, and drying the surface early defeats the required contact time.
