CSMLS Exam Review
A fingernail has been fixed in formalin,
routinely processed, and embedded in
paraffin. The tissue is found to be very
hard to cut. Which of the following pro-
cedures on the block will preserve the
tissue components, improve the section
quality, and make it easier to cut sec-
B
tions?
A) Treat with decalcifying agent
B) Soaking in a solution that softens ker-
atin
C) Soaking in water
D) Warming the block slightly
An alpha-hemolytic, catalase-negative,
Gram-positive coccus isolated from a
specimen showed a zone of inhibition
of 12 mm with a 5µg ethylhydrocupreine
disc.
What is the most appropriate next step?
C
A) Report the isolate as viridans strepto-
coccus
B) Report the isolate as Streptococcus
pneumoniae
C) Perform bile solubility test
D) Repeat the test using 10µg optochin
disc
1. A patient suffering from malaria was
started on antimalarial drug, Primaquine.
Within 2 days of therapy, the patient
showed signs of severe hemolysis with
low hemoglobin and increased indirect
A
bilirubin. A staining method using new
methylene blue was performed. Detec-
tion of which of the following will help in
the diagnosis?
, CSMLS Exam Review
A) Heinz bodies
B) Reticulocytes
C) Howell-Jolly bodies
D) Bite cells
Anti-s is found in a patient whose red
cells type as "s" positive.
Which of the following can explain the
likely cause of this result?
A) Presence of albumin in the test sys-
B
tem
B) A positive direct antiglobulin test on
patient's red cells
C) Anti-s showing dosage
D) A transfusion received six months pri-
or
Serum or plasma must be separated
from cells within two hours of collection.
Which of the following is an exception to
this rule?
a
a. Use of a gel separator tube
b. Freezing the specimen
c. Warming the specimen
d. Use of citrate
A platelet count was performed before
and after 10 PLT units were transfused
to a group AB patient.
How can this be interpreted? b
a. The patient should receive irradiated
platelets
b. The patient has developed antibodies
to the transfused platelets
c. The patient needs Group AB platelets
to be effective

d. Clinical data does not suggest any
need for platelets.
During an elevation of adrenal function,
a patient had plasma cortisol determina-
tion in the morning after awakening and
in the evening. The Laboratory results in-
dicated that the morning value was high-
er than the evening concentration.
