QUESTIONS AND SOLUTIONS RATED A+
✔✔Post-Analytical- quality assurance - ✔✔result reporting
critical values
notification guidelines
✔✔what should be included in the record filee of the worker personnel? - ✔✔HIPAA
regulation known by the employee
✔✔The blue filter modifies the yellow effect on the light giving it a more white light effect
- ✔✔to eliminate the yellow color emitted by the tungsten light bulb
✔✔the oil immersion is used for? - ✔✔it gathers light for the objective and increase
resolution. type B (high viscosity) is commonly used.
✔✔The X and Y in the microscope are used for: - ✔✔the values obtained bared plotted
on the x and y axis. This moves the mechanical stage or base left to right and the y
moves up and down or front to back.
✔✔sharp container is an: - ✔✔engineering control
✔✔NO sharps is in: - ✔✔Biohazard bag
✔✔precision means: - ✔✔closeness of repeat results (reproducibility). describes how
close test results are to one another when repeated analysis of the same material is
performed.
✔✔Accuracy - ✔✔closeness of the results to the true value. describes how close a
given test result is to the true value
✔✔1SD - ✔✔68.3%
✔✔2SD - ✔✔95.5%
✔✔3SD - ✔✔99.7%
✔✔Systemic error - ✔✔influences values consistency in 1 direction 2SD
REJECT RUN
✔✔Random error - ✔✔exist in all measurements and due to chance 1 3SD
reject run
✔✔active error - ✔✔interference between laboratorian and Patient's sample
,✔✔Latent error - ✔✔related to organization or design of a laboratory
✔✔variance - ✔✔a term that describes the factor that affect the measurement of an
analyte
ex: sample error
random analytical error
analytical systemic error
operator error
sample- day to day sample variation within a single patient
patient- patient variation (race, sex, age, health status)
✔✔shift - ✔✔refers to 6 consecutive points on one side of the mean
✔✔trend - ✔✔refers to 6 consecutive points increasing or decreasing that may cross the
mean
✔✔NATIONAL FIRE PROTECTION agency hazard code: - ✔✔RED= FLAMMABILITY
BLUE =HEALTH
YELLOW= REACTIVITY
WHITE= RADIOACTIVE ( MUST SEE OTHER HAZARD)
✔✔A mathematical measure of the spread (dispersion) of statistical data above and
below the average is called: - ✔✔Standard Deviation
✔✔The etched rings on the top of the pipette mean: - ✔✔that the last drop is to be
blown out after pipette drains
✔✔standard solution from 99.95 purity of the chemical can be retrieved are referred to
as: - ✔✔primary standard
✔✔The statistical term that most specifically describes analytic precision is: -
✔✔Coefficient of Variation
✔✔Two control sera are desirable for each general chemistry procedure. which of these
combination would be appropriate. - ✔✔mean of normal range and abnormal (hight)
✔✔these agency (CMS, COLA, CAP, and JHACO) regulates: - ✔✔Standard operation
procedure manual
✔✔A nurse brings an unlabeled tube to the lab, what should be done? - ✔✔check the
book of rejection criteria
✔✔wearing goggles is required by: - ✔✔OSHA
, ✔✔OSHA - ✔✔Occupational Safety and Health Administration
✔✔what would you do when you spill chemical on skin - ✔✔rinse under a lot of water
✔✔How do you calibrate a refractometer? - ✔✔distilled water
✔✔chain of custody refers to the document trail relevant to the custody, control,
transfer, analysis, and disposition of physical and electronic materials . required in
cases of: - ✔✔drug testing
HIV testing
✔✔what kind of spills happen if you centrifuge a tube without a cap: - ✔✔Aerosol
hazard
✔✔true about HIPPA - ✔✔prohibit you from releasing any clinical result from a patient
to any public clinic.
Federal law that protects the privacy and security of an individual's health information
✔✔Universal Precautions - ✔✔always wash your hands. all samples are handled as if
infectious
✔✔How can you contract HIV/HBV - ✔✔puncture wound by contaminated needle or
sharp object
broken/ damaged skin result in infectious fluid or tissue entering body
mucous membrane enter thru eyes, nose, mouth
✔✔autoclave is - ✔✔121C , 15lbs pressure, 15-30 minutes
✔✔what method is used to establish a quality control - ✔✔Levy Jennings Chart
✔✔which agency regulates market entry of instruments and reagents - ✔✔FDA (food
and drug administration)
✔✔which bloodborne pathogen are the greatest concern to laboratories? - ✔✔HBV and
HIV
✔✔when the control reagents should be assay to ensure proper reliability and
determine a new standard curve? - ✔✔after first opened
every time you run a control and patient
when you receive a new lot to compare with the old one
✔✔what is "relex testing" - ✔✔the performance of a test on a patient specimen only
after a particular analyte is ABNORMAL or outside of a predetermined range
