If a 10x eyepiece is used with a 45x objective, what is the total magnification?
a.4.5
b.45
c.450
d.4500
c. 450
The total magnification of a microscope can be found by multiplying the eyepiece magnification
by the objective magnification. So, 10 times an objective magnification of 45 is equal to 450.
What category of bioterrorism agents include pathogens that are moderately easy to disseminate,
result in moderate and low morbidity rates, and require specific enhancements of the CDC's
diagnostic capacity and enhanced disease surveillance?
a.Category A
b.Category B
c.Category C
d.Category D
,b. Category B
Bioterrorism agents are a concern to laboratories. These agents are divided into categories A, B
and C; and Category B agents have the second highest priority. Category B agents have
moderate morbidity (suffering from the disease) with low mortality (death) rates. Ricin toxin is
an example of Category B agent.
Which term refers to blood that is collected directly after a meal?
a.Blood spot collection
b.Fasting collection
c.Postprandial specimen
d.Preprandial specimen
c. Postprandial specimen
Blood collected directly after a meal is defined as a postprandial specimen.
What is the name of the substance in which solute is dissolved in?
a.Buffer
b.Chemical
c.Solution
d.Solvent
d. Solvent
A solvent is the substance in which the solute is dissolved.
The concept where all human blood and certain human body fluids are treated as if known to be
infectious for HIV, HBV, and other bloodborne pathogens is known as
a.Appropriate Precautions.
b.Regulated Waste Precautions.
c.Standard Precautions.
d.Universal Precautions.
d. Universal Precautions.
Universal Precautions is an approach to infection control. According to the concept of Universal
Precautions, all human blood and certain human body fluids are treated as if known to be
infectious for HIV, HBV, and other bloodborne pathogens.
,What type of plasma or serum is milky-white in color and may interfere with chemical
determinations, such as triglyceride or nephelometric assays?
a.Hemolyzed
b.Icteric
c.IV contaminated
d.Lipemic
d. Lipemic
The presence of lipids, or fats, in serum or plasma can cause this abnormal appearance. Often,
the lipemia results from collecting the blood from the patient too soon after a meal.
What does this symbol represent?
a.Corrosive
b.Explosive
c.Flammable
d.Health hazard
a. Corrosive
The pictograms on all labels are designed to alert users of the potential hazard in which they
may be exposed. The corrosion pictogram above represents potential exposure to skin
corrosion/burns, eye damage, and corrosion to metals.
How many milliliters can a 3% solution make if 6 grams of solute are available?
a.100 mL
b.200 mL
c.300 mL
d.400 mL
b. 200 mL
3% of solution means 3 g of solute in 100 mL of solution.
1 g of solute contains = (100/3) mL
So, in 6 g of solute = (100/3) x 6 =200 mL.
200 mL of 3% solution is needed for 6 g of solute.
What does this symbol represent?
, a.Corrosive
b.Explosive
c.Flammable
d.Health hazard
c. Flammable
The pictograms on all labels are designed to alert users of the potential hazard in which they
may be exposed. The flame pictogram above represents potential exposure to flammables,
pyrophorics, self-heating, emitting of flammable gas, self-reactions, and organic peroxides.
To the nearest degree, what is 40° Fahrenheit converted to Celsius?
a.4° C
b.6° C
c.10° C
d.14° C
a. 4° C
C= (F-32) 5/9
C=(40-32) 5/9
C=(8) 5/9
C=4.4
The nearest degree is 4.
What category of testing involves microscopic evaluation (i.e., wet mount, Potassium hydroxide
preparation, fern test, etc.) by a physician in the office for their own patient?
a.Moderate Complexity Testing
b.Point-Of-Care Testing (POCT)
c.Provider-Performed Microscopy (PPM)
d.Waived Testing
c. Provider-Performed Microscopy (PPM)
To meet the criteria for inclusion in the Provider-Performed Microscopy (PPM) category,
procedures must follow these specifications: The examination must be personally performed by
the practitioner (defined as a physician), a midlevel practitioner (defined as a physician, a
midlevel practitioner under the supervision of a physician), or a dentist. The procedure must be
categorized as moderately complex. The primary test instrument is the microscope (limited to
brightfield or phase-contrast microscopy). The specimen is labile. Control materials
are not available. Specimen handling is limited. Proficiency testing is not required; however,
