CORRECT Answers
1. Procainamide -Answer: NAPA
-p. 86-Ant antiarrhythmic drug that has a metabolite with the same drug
action
-Procainamide is metabolized to N-Acetylprocainamide (NAPA)
- Must quantify both. Although they have the same drug affect, difference
in half- life may cause NAPA to accumulate in the blood and produce toxic
affects even at therapeutic levels of procainamide.
2. loose clusters of small -Answer: Trichophyton mentagrophytes -Trichophyton is the only Der-
spherical microconi- matophyte with two colony types : macroconidia and microconidia. - T.
dia, positive urease mentagrophytes characteristically produce "grapelike clusters" of micro-
conidia. - Positive in the hair perforation test.
3. Beta -HCG tumor Answer: chorocarcinoma
marker -The are are 2 forms of hCG Alpha (common form) and Beta (unique form)
4. 5HIAA 5-hydroxyin- -Answer: carcinoid tumors -5HIAA: primary metabolite of serotonin, a
doleacetic acid chemical substance (neurotransmitter) that transmits messages between
nerve cells. -Large quantities of serotonin and 5-HIAA may be produced by
some carcinoid tumors.- Carcinoid tumors are slow-growing noncancer-
ous or cancerous neuroendocrine masses that can form in the GI tract,
especially in the appendix, and in the lungs.
5. Proteus vulgaris vs P. P. vulgaris is indole pos. P. mirabilis is indole neg
mirabilis indole test
6. Hydatid cyst fluid used to neutralize Anti-P1 antibody
7. Antacid overdose Check pH
8. Prolonged PT, PTT, heparin contamination
and thrombin af-
, ter collecting from
catheter
9. mixing study that DRVVT (Dilute Russell Viper Venom Test)
was performed with
a prolonged PTT that
couldn't be corrected
10. two pt's ran in dupli- check the CaCl/phospholipid reagent delivery
cate (PT and PTT). The
PTT seemed to always
be prolonged but PT
looked ok
11. Patient is on Decreased protein C
coumadin therapy,
what will be affected
12. Lot's of stomatocytes Liver disease
13. Burr cells Uremia
14. Picture of target cells anti-lysing target cells are what increased the white count? Erythrocytes
with hemoglobin C containing hemoglobin C do not lyse normally (sickle cell diseases)
crystals. The white
count was high on in-
strument 1, so a sec-
ond instrument was
used with a stronger
lysing agent, and the
white count was cor-
rected
, 15. A sodium citrate tube recollect with decreased anticoagulant. high hct (>55%) causes low plas-
was drawn for a HCT ma so you need less anticoagulant
on a pt but the hemat-
ocrit was abnormal
16. Question that gives a check for lipemia (elevates HGB)
red blood cells count,
HGB, and HCT. I did
the rule of 3 and found
that the HGB didn't
meet the rule of 3 be-
cause it was too high
17. PBS with an elevated -Answer: howell jolly bodies= DNA= Wright Stain
reticulocyte count and -Peppenheimer- Prussian blue stain
howell jolly bodies in -which is not taken up by reticulocytes
the RBC's -helpful in differentiating the two.
-Reticulocytes=Supravital/ new methylene blue stain
18. what is composed of howell jolly bodies
DNA? -wright Stain
19. what falsely increases vibration, tilting of tube, higher temps, >1 hr test time, improper mixing
ESR of blood, improper dilution
20. factors decreasing Polycythemia, Microcytosis (Hb C), Sickle cells, spherocytes, Anti-in-
ESR flammatory medications, Hypogammaglobulinemia, Hypofibrinogenemia
(DIC), High WBC count, Hyperviscosity
21. Factors increasing ESR Anemia, Macrocytosis, Female gender, Age >50 years, Obesity, Pregnan-
cy, Hypercholesterolemia, cancer, multiple myeloma, rouleaux, infections,
inflammation
