◍ According to AABB Standards, at least 90% of all Apheresis Platelets units
tested shall contain a minimum of how many platelets? 5.5 X 10^11 5.0 X
10^11 3.0 X 10^11 6.5 X 10^11Also, how are apheresis platelet units made
(2 steps), and what is returned to the blood donor?.
Answer: At least 90% of platelet apheresis units sampled must contain at
least 3.0 x 10^11 platelets.Made by 1) withdrawing blood from a donor, and
2) withdrawing platelets from the donor's blood (the withdrawn platelets are
the apheresis platelet unit), and the remaining blood components (i.e. every
component except the withdrawn platelets) is returned to the donor.
◍ 17-Ketosteroids are produced in which of the following? Also, what is the
name and type of hormone often broken down to form 17-ketosteroids, can
other hormones be released by both female and male adrenal glands, and
what other organ in males can form 17-ketosteroids? Adrenal glands
Hypothalamus Thyroid glands Pituitary glands.
Answer: A. Adrenal glandsAndrogens (male sex hormones) are broken
down, yes, testes.
◍ In which of the following blood group types is the expression of antigens
weakened, or in some cases negative, during pregnancy? P Lewis i/I
KellAlso, what 2 things can form because of this, why can this be
significant, and how can the expression of the correct choice above be
described in pregnancies?.
Answer: B. LewisWeakened Lewis antigens can cause Lewis a and b
antibodies to form, potentially significant because Lewis antibodies can
(rarely) cause hemolytic transfusion reactions during pregnancies, and the
weakening of Lewis antigens can be described as transient (i.e., they go
back to normal a short time after giving birth).

◍ A potential participant has a systolic bp of 130, LDL of 135, and is 35 years
old. Are they at risk for CVD?.
Answer: No, they only show one risk factor (LDL choloesterol of 130 or
higher).
◍ Name some reasons why there is expected growth in Group Fitness jobs

◍ The Cardiac Cycle.
Answer: The period from the beginning of one heartbeat to the beginning of
the next.
◍ Eosinophils in LAP (Leukocyte Alkaline Phosphatase) score which of the
following? -Not counted -Double the value -Constant value -None of the
aboveAlso, what is an LAP score, where is the LAP enzyme primarily found
(and in what two forms of this cell is LAP found), to which white blood
cell(s) is an LAP score typically applied, and what is a cytochemical
stain?How does an LAP score test work (hints for each step: 1) what type of
slide is used, 2) what type of stain is used (what does this type of stain bind
to), 3) what does an optimal area on the slide look like (3 characteristics)
and what does the target cell look like, 4) how are cells graded (which
cells?) and how many cells are counted, and 5) how is the result calculated)?
, What is the normal range of LAP scores, what can be indicated by low
scores, and what about high scores (and what condition can cause high
scores)?.
Answer: A. Not countedAn LAP score is a measure of the activity of the
Leukocyte Alkaline Phosphatase (LAP) enzyme, primarily found in mature
neutrophils, an LAP score is typically only scored for neutrophils (mature
and band neutrophils), a cytochemical stain uses chemical dyes that bind
with specific biomolecules in specific organisms (i.e, enzymes). LAP Score
Test: 1) smear blood sample on a hemocytometer (a slide with a grid), 2)
apply cytochemical stain (dye binds to specific chemicals formed by the
LAP enzyme), 3) identify an area on slide where neutrophils are evenly
distributed, not overlapping too much, and not too sparse; neutrophils have a
multilobed nucleus, 4) neutrophils are graded consecutively on a scale of 0
to 4+ depending on how dark they are stained (100 cells are assessed), and
5) the 100 scores are added together to get the final LAP score. LAP score
normal range: 15-130, low scores: possible Chronic Myeloid Leukemia
(CML), high scores: typically non-cancerous leukemoid reactions (wide
variety of causes).
◍ Moth balls (naphtalene) poisoning may show which of the following red cell
characteristics? Also, for which group of people is this the most common,
and what pathologies can be formed as a consequence of Heinz body
formation (name 3)? Howell-Jolly bodies Ovalocytes Sickle cells Heinz
Bodies.
Answer: D. Heinz bodiesMost common for children, 3 pathologies include:
1) hemolytic anemia, 2) hemoglobinuria, and 3) mild methemoglobinemia.
◍ Which of the following is sometimes referred to as the "pork worm" due to
it being typically encountered in undercooked pork products: Also, what is a
good mnemonic to rememebre this? Trichinella spiralis Trichuris trichiura
Enterobius vermicularis Taenia saginat.
Answer: A. Trichinella spiralisMnemonic: pigs (pork) have a spiral
("spiralis") tail and (in Charlotte's Web) Charlotte convinces Wilbur (a pig)
to do tricks ("trichs", to remember "Trichinella").
, ◍ Which of the following tests is used to identify Hairy Cell Leukemia
(HCL)? Also, what does a blood smear of Hairy Cell Leukemia (HCL) look
like, how do HCL cells react to this type of staining, and what colors can
these cells appear as in the experimental results? Myeloperoxidase
Tartrate-resistant acid phosphatase Tartrate-resistant alkaline phosphatase
Sudan Black.
Answer: B. Tartrate-resistant acid phosphatase (TRAP)HCL cells have fine
hair-like projections extending from their cell membranes, they demonstrate
strong positivity for tartrate-resistant acid phosphatase (TRAP) staining,
bright red or dark purple/red-violet..
◍ What primary functions does the human skeleton perform?.
Answer: SupportMovementProtectionStorageHemopoiesis

2 common methods)..
Answer: A. N-acetylprocainamide (NAPA)NAPA levels can be measured
by high performance liquid chromatography or immunoassays.
◍ What antibiotic type do Enterococci cells have a high-level resistance to,
what is this resistance called, and what drug often given with
