,
,Which of the following statements is correct when handling cryogenic liquids? Wear proper personal
protective equipment, including a lab coat that is buttoned, heavy gloves and a face shield or safety
goggles.
Which of the following statements is correct regarding safety cabinets? Large amounts of volatile
solvents must be stored in a safety cabinet that is approved by NFPA and meets OSHA standards.
Which of the following statements is correct regarding laboratories and waste material? Laboratories
are identified by Resource Conservation and Recovery Act (RCRA) as "waste generators."
The CDC recommends vigorous rubbing together of all lathered surface for at least: 15 seconds
Which of the following statements describes "engineered control"? Safety equipment that isolates
or removes the bloodborne pathogen hazard from the workplace and represents the preferred method
for controlling hazards
Which of the following statements usually determines the acceptable range when evaluating quality
control results? The 95% confidence interval of the mean
Which of the following is an example of nominal type data? Numbers applied to nonnuméric
variables for example blood types could be coded as group O=1, group A= 2 etc.
A 13s quality control rule violation is defined as: One control result that exceeds +3 s.
Which statement listed below is a reason to ireject an analytical run? Two consecutive control results
exceed 2 standard deviations above or below the mean.
A graph that shows the difference between your laboratory result and a comparative method results
along the x-axis and the percent difference along the y-axis is referred to as which of the following?
Bias graph
Which of the following practices is inappropriate when establishing quality controls ranges?
Exclusion of any quality control results greater than +2 standard deviation from the mean
8) Which of the following statistics is used to qualify the strength of the relationship between two
variables? Correlation coefficient
9) An important difference between parametric statistics and nonparametric statistics is that
nonparametric statistics is distribution free, whereas parametric statistics: Presumes a Gaussian
distribution.
Recovery experiments, testing proficiency samples and estimating bias are all examples of procedures
used to assess: Accuracy.
A significant limitation of least squares regression analysis is: Nonlinearity of the data will affect both
the slope and intercept.
Analysis of variance (ANOVA) is an appropriate statistics to evaluate three or more sets of data among
each other, but it does NOT reveal: Which set of data is not in agreement with the other data.
Deming's linear regression analysis attempts to: Overcome shortfalls in the least squared method.
, Ion-exchange filters remove which of the following from a water source? Ions to reduce the
mineral content of water
Activated carbon filters remove:Organic compounds from water.
A 0.22-micron filter will remove: Particles with a diameter of 2.2 microns.
The unit of resistivity is: M omega cm.
Microbiological impurities in source water are reported in which format? Colony forming units
per mL (Cfu/mL) clinical laboratory
According to CLSI, the resistivity of clinical laboratory reagent water (CLRW) must be: > 10 M omega.
cm.
Which of the following should not be storied in borosilicate glass because it will etch the inside surface
of the glass container? Strong bases (caustics)
Low actinic glassware has which of the following properties? High High thermal resistance with an
amber or red color added as an integral part of the glass
Care must be taken before selecting polyethylene plastic for use as test tubes and disposable transfer
pipets because: Polyethylene can bind or absorb proteins, dyes, stains, and picric acid.
Which of the following classes of glassware, including pipets, is manufactured and calibrated to deliver
the most accurate volume of liquid? A
A to deliver or TD pipet is designed to: Drain by gravity.
Which of the following devices is used to calibrate laboratory thermometers? Gallium melting point
cell
class A fire involves: Ordinary combustible material including paper and wood.
OSHA standards are written in which of the following documents? Codes of Federal Regulations
(CFRS)
Which of the following practices is inappropriate when establishing quality controls ranges?
Exclusion of any quality control results greater than +2 standard deviation from the mean
Liquid nitrogen is an example of which of the following? Cryogen

Chemical hazards
Sources of nonionizing radiation include which of the following? Microwaves, tungsten-halogen lamps,
xenon lamps
Which of the following statements describes the proper method of storing chemicals in the laboratory?
According to their chemical properties and classifications
