1Air flow in a microbiology laboratory should be:
- Afrom lower to higher risk areas
- Bminimized as much as possible
- Coptimized to prevent the settling of dangerous aerosols
- Dwell-filtered by recirculating it through numerous filters before recycling
2Procedures such as grinding, mincing, vortexing, and preparing smears:
- Aare hazardous and should be performed while wearing gloves and gown protection.
- Bcreate aerosol droplets and should be performed only in an approved biosafety cabinet.
- Cshould be avoided with specimens known to contain infectious agents
- Dproduce a spill hazard and should be performed over an absorptive mat.
3Class I biological safety cabinets:
- Asterilize the air as it passes over the material in the cabinet
- Bprotect the environment from contamination by biological agents by filtering the air as it is exhausted from the cabinet.
- Care completely enclosed and have gloves that enable the worker to manipulate the material in the cabinet.
- Dare often called laminar flow hoods.
4Optimal protection of specimen, personnel, and environment is accomplished with which class of biological safety cabinet?
- AClass I
- BClass II
- CClass III
- DClass IV
5The method of choice for sterilizing items such as antibiotic solutions, chemicals, radioisotopes, and vaccines that are heat-sensitive is:
- Adry, low temperature heat.
- Bmoist, low temperature heat.
- Cfiltration
- Dchemical
6To be sterilized in an autoclave, infectious medical waste should be:
- Apacked tightly to avoid dangerous pressure pockets.
- Bprocessed for 15 to 20 minutes at 121 C and 30 pounds per square inch (psi) pressure.
- Cprocessed for 30 to 60 minutes at 132C and 15 psi pressure
- Dprocessed for at least 1 hour at 121 C and 15 psi pressure.
7The autoclave sterilizes material by:
- Aapplying dry heat at high temperatures and pressure.
- Binfusing gaseous chemicals that kill organisms.
- Capplying moist heat at high temperatures and increased pressure.
- Dcleaving protein bonds found in most biological agent cell walls.
