1. Aerosol transmissible diseases (ATDs) are diseases transmitted when infectious agents, which are suspended or present in particles or droplets, contact the mucous membranes or are inhaled.
A. TRUE B. FALSE2. Both respirators and face masks may be considered “masks.”
A. TRUE B. FALSE3. The purpose of a face mask, when worn by a patient suspected or confirmed with an illness such as influenza or tuberculosis, is to protect the wearer from large droplets or sprays of infectious body fluids.
A. TRUE B. FALSE4. The purpose of a respirator, when worn by health care personnel, is typically to protect the wearer by reducing the concentration of infectious particles in the air inhaled by the wearer.
A. TRUE B. FALSE5. Closed suctioning systems do not typically minimize the dispersion of aerosol.
A. TRUE B. FALSE6. Which of the following statements regarding surgical masks is most accurate?
A. When worn by health care personal, surgical masks protect against small airborne particles. B. When worn by health care personal, surgical masks do not protect against small airborne particles. C. When worn by health care personal, surgical masks do not protect the wearer’s nose/mouth from splashes or sprays of large droplets of body fluids. D. When worn by health care personal, surgical masks reduce a health care personal's inhalation of both large droplets and small airborne particles.7. The CDC and HICPAC describe the distinction between droplet transmission and airborne transmission based on particle size and the distance and time over which the pathogens remain infectious.
A. TRUE B. FALSE8. When Droplet Precautions are recommended, surgical masks function to reduce the transmission of large infectious droplets between the source (patient) and the mucosal surfaces of a susceptible host (health care personnel).
A. TRUE B. FALSE9. Which of the following statements is most accurate?
A. Particles up to 100 micrometers in diameter are known to be inhalable into the nose or mouth. B. Particles up to 200 micrometers in diameter are known to be inhalable into the nose or mouth. C. Particles up to 300 micrometers in diameter are known to be inhalable into the nose or mouth. D. Particles up to 400 micrometers in diameter are known to be inhalable into the nose or mouth.10. The CDC and HICPAC recommend the use of respiratory protection when aerosol-generating procedures are performed on patients suspected or known to be infected with an illness or pathogen requiring Airborne Precautions.
A. TRUE B. FALSE11. Which of the following statements is most accurate?
A. Filter class N95 filters at least 95% of airborne particles and is resistant to oil. B. Filter class N99 filters at least 99% of airborne particles and is resistant to oil. C. Filter class N100 filters at least 99.97% of airborne particles and is resistant to oil. D. Filter class R95 filters at least 95% of airborne particles and is resistant to oil.12. The purpose of a hazard evaluation is to identify and evaluate potential exposures in the workplace that might require the use of respiratory protection.
A. TRUE B. FALSE13. The CDC recommends that personnel performing an aerosol-generating procedure on a patient suspected or confirmed with seasonal influenza wear at least an N95 respirator.
A. TRUE B. FALSE14. Which of the following statements is most accurate?
A. All employees required to wear tight-fitting respirators must be fit tested after receiving medical clearance, prior to respirator use, and every 4 weeks thereafter. B. All employees required to wear tight-fitting respirators must be fit tested after receiving medical clearance, prior to respirator use, and every 6 months thereafter. C. All employees required to wear tight-fitting respirators must be fit tested after receiving medical clearance, prior to respirator use, and annually thereafter. D. All employees required to wear tight-fitting respirators must be fit tested after receiving medical clearance, prior to respirator use, and every 18 months thereafter.15. Fit test records must be kept on file until a new fit test is completed.
