Nephelometry involves the measurement of
A. Light scatter
B. Atomic absorption
C. Light absorption
D. Light transmission - ANSWER ->C. Light absorption When
light strikes a particle in a solution, it can be absorbed,
transmitted, reflected, or scattered. Nephelometry is used to
measure the light scattered by particles in a solution. It is
useful for measuring protein levels in fluids, and antigen-
antibody
complexes
Most potent activator enzyme is
A. Magnesium
B. Sodium
C. Potassium
D. AOTA - ANSWER ->A. Magnesium
Over 300 enzymes require the presence of magnesium ions for
their catalytic action, including all enzymes utilizing or
synthesizing ATP, or those that use other nucleotides to
synthesize DNA and RNA
,A characteristic morphologic feature in hemoglobin C disease is
A. Macrocytosis
B. Spherocytosis
C. Rouleaux formation
D. Target cells - ANSWER ->D. Target cells
Codocytes also known as target cells are RBCs that have the
appearance of a shooting target with a bullseye
Two consecutive values in which they are in the +2SD of the
same mean or in the -2SD of the same mean
A. 2:2s
B. 10:x
C. 1:2s
C. R:4s - ANSWER ->2(2s) is a Westgard multirole that indicates
a reject of a run when 2 consecutive control observations are
on the same side of the mean and exceed either the mean plus
2s or mean minus 2s
Precipitation of ribosomes and RNA
A. Heinz bodies
B. Howell-Jolly bodies
C. Basophilic stippling
D. Auer rods - ANSWER ->C. Basophilic stippling
1. Fine stippling = polychromatophilia (production of RBCs)
2. Coarse stippling = lead poisoning
, Mycobacterium tuberculosis - ANSWER ->Mycobacterium
tuberculosis is an obligate pathogenic bacterial species in the
family Mycobacteriaceae and the causative agent of
tuberculosis. M. tuberculosis has an unusual, waxy coating on
its cell surface primarily due to the presence of mycolic acid.
Cells are curved rod-shaped and are often seen wrapped
together, due to the presence of fatty acids in the cell wall that
stick together. This appearance is referred to as cording, like
strands of cord that make up a rope. M. tuberculosis is
characterized I tissue by cadeating granulomas containing
Langhans giant cells, which have a "horseshoe" pattern of
nuclei.
Description of Zygomycetes
A. Septate hyphae with basidiospores
B. Septate hyphae with sporangiospores
C. Aseptate hypae with sporangiospores
D. Aseptate hyphae with basidiospores - ANSWER ->C. Aseptate
hypae with sporangiospores
According to AABB standards, Fresh Frozen Plasma (FFP) must
be infused within what period of time following thawing?
A. 24 hours
B. 36 hours
C. 48 hours
D. 72 hours - ANSWER ->A. 24 hours
