The greatest risk of cross-contamination in the pulmonary function laboratory is associated with:
A) Failure to use bacteria filters for spirometry
B) Inadequate disinfection of reusable nebulizers
C) Moisture inside dry rolling-seal spirometers
D) Pulse oximetry finger sensors

Question

Quizplus · Accepted Answer

Reusable nebulizers are a potential source of contamination if they are not properly cleaned and disinfected between patients. Failure to adequately disinfect them can lead to the spread of infectious diseases such as tuberculosis or influenza. Other measures such as using bacteria filters and regularly checking and cleaning equipment like dry rolling-seal spirometers and pulse oximetry finger sensors can also help prevent cross-contamination, but are not the greatest risk.
