WITH VERIFIED SOLUTIONS.
Procainamide - CORRECT ANSWER -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.
loose clusters of small spherical microconidia, positive urease - CORRECT
ANSWER -Answer: Trichophyton mentagrophytes -Trichophyton is the only
Dermatophyte with two colony types : macroconidia and microconidia. - T.
mentagrophytes characteristically produce "grapelike clusters" of microconidia. -
Positive in the hair perforation test.
Beta -HCG tumor marker - CORRECT ANSWER Answer: chorocarcinoma
-The are are 2 forms of hCG Alpha (common form) and Beta (unique form)
5HIAA 5-hydroxyindoleacetic acid - CORRECT ANSWER -Answer: carcinoid
tumors -5HIAA: primary metabolite of serotonin, a 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 noncancerous or cancerous neuroendocrine masses that
can form in the GI tract, especially in the appendix, and in the lungs.

Proteus vulgaris vs P. mirabilis indole test - CORRECT ANSWER P. vulgaris is
indole pos. P. mirabilis is indole neg
Hydatid cyst fluid - CORRECT ANSWER used to neutralize Anti-P1 antibody
Antacid overdose - CORRECT ANSWER Check pH
Prolonged PT, PTT, and thrombin after collecting from catheter - CORRECT
ANSWER heparin contamination
mixing study that was performed with a prolonged PTT that couldn't be corrected -
CORRECT ANSWER DRVVT (Dilute Russell Viper Venom Test)
two pt's ran in duplicate (PT and PTT). The PTT seemed to always be prolonged but
PT looked ok - CORRECT ANSWER check the CaCl/phospholipid reagent
delivery
Patient is on coumadin therapy, what will be affected - CORRECT ANSWER
Decreased protein C
Lot's of stomatocytes - CORRECT ANSWER Liver disease

Picture of target cells with hemoglobin C crystals. The white count was high on
instrument 1, so a second instrument was used with a stronger lysing agent, and
the white count was corrected - CORRECT ANSWER anti-lysing target cells are
what increased the white count? Erythrocytes containing hemoglobin C do not lyse
normally (sickle cell diseases)
A sodium citrate tube was drawn for a HCT on a pt but the hematocrit was
abnormal - CORRECT ANSWER recollect with decreased anticoagulant. high
hct (>55%) causes low plasma so you need less anticoagulant
Question that gives a 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 because it was too high - CORRECT
ANSWER check for lipemia (elevates HGB)
PBS with an elevated reticulocyte count and howell jolly bodies in the RBC's -
CORRECT ANSWER -Answer: howell jolly bodies= DNA= Wright Stain
-Peppenheimer- Prussian blue stain
-which is not taken up by reticulocytes
-helpful in differentiating the two.
-Reticulocytes=Supravital/ new methylene blue stain
what is composed of DNA? - CORRECT ANSWER howell jolly bodies
-wright Stain
