◍ Which of the following enzymes has the longest elevation after
Myocardial Infarction (MI)?
CK-MB
Myoglobin
Troponin
AOTA. Ans: C. Troponin
Troponin is elevated up to 10-14 days after Myocardial Infarction.
◍ Lactic acid specimen:
Chilled and separated from cells
Heated
Room temperature
,Request EDTA sample only. Ans: A. Chilled and separated from cells
Feedback Special Handling: No tourniquet. Place on ice immediately
and deliver to lab or aliquot within 15 minutes. DO NOT FREEZE
WHOLE BLOOD SPECIMEN.
◍ Specific gravity measured by refractometer: 1.035. Protein and
glucose both trace in reagent strip:
Presence X-ray medium
Albuminuria
Glucosuria
Normal. Ans: A. Presence X-Ray medium
Feedback Xray medium/Radiographic dye can cause erroneous results
in urine specific gravity measurement.
◍ A patient with walking pneumonia is being treated with penicillin.
State one possible condition why the patient is not recovering:
The organism produces beta lactamase
,The organism has no cell wall
The organism has capsule
The organism produces an enzyme that neutralizes the antibiotic.
Ans: B. The organism has no cell wall.
Feedback Pneumonia caused by Mycoplasma pneumoniae is routinely
treated with antibiotics, although the disease is usually self-limiting.
The disease is treated with macrolide, tetracycline, or fluoroquinolone
classes of antibiotics. All mycoplasmas lack a cell wall and, therefore,
all are inherently resistant to beta-lactam antibiotics (e.g., penicillin).
◍ What is the coefficient of variation if the mean is 90 and the
standard deviation is 5.48?
2.75
6.09
5.68
30. Ans: B. 6.09
, Feedback:
CV= SD/meanX100,
(5.48/90)X100= 6.09.
◍ Blood smear below denotes Hairy Cell Leukemia (HCL), which
of the following test is used to identify this type of leukemia?
Image. 1
Myeloperoxidase
Tartrate-resistant acid phosphatase
Tartrate-resistant alkaline phosphatase
Sudan Black. Ans: B. Tartrate-resistant acid phosphatase
Feedback:
Hairy cells demonstrate strong positivity for tartrate-resistant acid
phosphatase (TRAP) staining. The hairy cells are larger than normal
and positive for CD19, CD20, CD22, CD11c, CD25, CD103, and
FMC7.
◍ Use to differentiate Salmonella from Citrobacter:
Lysine decarboxylase
