MLS ASCP Exam Recall Questions & Correct Answers
1. Procainamide NAPA
2. loose clusters of small spherical mi-Trichophyton mentagrophytes
croconidia, positive urease
3. BHCG tumor marker chorocarcinoma
4. 5HIAA carcinoid tumors
5. Proteus vulgaris vs P. mirabilis in- P. vulgaris is indole pos. P. mirabilis is
dole test indole neg
6. Hydatid cyst fluid used to neutralize Anti-P1 antibody
7. Antacid overdose Check pH
8. Prolonged PT, PTT, and thrombin af-heparin contamination
ter collecting from catheter
9. mixing study that was performed DRVVT (Dilute Russell Viper Venom
with a prolonged PTT that couldn't Test)
be corrected
10. two pt's ran in duplicate (PT and check the CaCl/phospholipid reagent
PTT). The PTT seemed to always be delivery
prolonged but PT looked ok
11. Patient is on coumadin therapy, Decreased protein
what will be affected
12. Lots of stomatocytes Liver disease
13. Burr cells Uremia
14. Picture of target cells with hemo- anti-lysing target cells are what in-
globin crystals. The white count creased the white count? Erythro-
was high on instrument 1, so a sec- cytes containing hemoglobin do
ond instrument was used with a not lyse normally (sickle cell dis-
stronger lysing agent, and the white eases)
count was corrected
, 15. A sodium citrate tube was drawn forrecollect with decreased anticoagu-
a HCT on a pt but the hematocrit waslant. high hct (>55%) causes low
abnormal plasma so you need less anticoagu-
lant
16. Question that gives a red blood check for lipemia (elevates HGB)
cells count, HGB, and HCT. I did the
rule of 3 and found that the HGB
didn't meet the rule of 3 because it
was too high
17. PBS with an elevated reticulocyte Prussian blue for howell jolly bodies
count and howell jolly bodies in the made of iron. Prussian blue stain,
RBC's which is not taken up by reticulocytes,
is helpful in differentiating the two.
18. what RBC inclusion is composed of howell jolly bodies
DNA?
19. what falsely increases ESR vibration, tilting of tube, higher temps,
>1 hr test time, improper mixing of
blood, improper dilution
20. factors decreasing ESR Polycythemia, Microcytosis (Hb ),
Sickle cells, spherocytes, Anti-in-
flammatory medications, Hypogam-
maglobulinemia, Hypofibrinogene-
mia (DIC), High WBC count, Hyper-
viscosity
21. Factors increasing ESR Anemia, Macrocytosis, Female gen-
der, Age >50 years, Obesity, Preg-
nancy, Hypercholesterolemia, can-
cer, multiple myeloma, rouleaux, in-
fections, inflammation
22. what falsely decreases ESR low blood/ room temps, air bubbles,
tests <1 hr, improper mixing of blood,
improper dilution
