Which of the following condition is the most common cause of
increase anion gap?
A. Metabolic alkalosis
B. Metabolic acidosis
Respiratory acidosis
Respiratory alkalosis
B. Metabolic acidosis
High anion gap metabolic acidosis is caused generally by the body
producing too much acid or not producing enough bicarbonate. This
is often due to an increase in lactic acid or ketoacids, or it may be a
sign of kidney failure. More rarely, high anion gap metabolic acidosis
may be caused by ingesting methanol or overdosing on aspirin.
Which of the following enzymes has the longest elevation after
Myocardial Infarction (MI)?
CK-MB
Myoglobin
Troponin
AOTA
,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
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
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
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
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
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
ONPG
Indole
Vogues Proskauerterm-9
A. Lysine decarboxylase
Feedback:
Salmonella (+); Citrobacter (-)
Arrange the common Rh antigens according to immunogenicity
(greatest to least):
D>c>E>C>e
D>C>E>c>e
D>c>E>e>C
C>D>c>E>e
A. D>c>E>C>e
Feedback Most immunogenic D > c > E > C > e least immunogenic.
Most common error in Polymerase Chain Reaction (PCR) is NUCLEIC
ACID CONTAMINATION.
A True (Correct Answer)
B False
A. True
