TOPIC 1: RED BLOOD CELL FUNCTION AND DISORDERS
10 Questions • 10.0% of Exam • This topic covers the structure, function, and disorders related to red blood cells, including
hemoglobin composition and associated pathologies.
QUESTION 1
After experiencing extreme fatigue and polyuria, a patient's basic metabolic panel is
analyzed in the laboratory. The result of the glucose is too high for the instrument to
read. The laboratorian performs a dilution using 0.25 mL of patient sample to 750
microliters of diluent. The result now reads 325 mg/dL. How should the techologist
report this patient's glucose result?
[A] 325 mg/dL
[B] 1300 mg/dL
[C] 975 mg/dL
[D] 1625 mg/dL.
Answer: B;
The correct answer for this question is 1300 mg/dL. The laboratorian performed a 1:4 dilution by adding 0.25
mL (or 250 microliters) of patient sample to 750 microliters of diluent. This creates a total volume of 1000
microliters. So, the patient sample is 250 microliters of the 1000 microliter mixed sample, or a ratio of 1:4.
Therefore, the result given by the chemistry analyzer must be multiplied by a dilution factor of 4. 325 mg/dL x
4 = 1300 mg/dL.
QUESTION 2
An individual with type AB blood will demonstrate the complete absence of which of
the following antigen sites?
[A] A
[B] B
[C] H
[D] None of the above.
Answer: D;
The A and B antigens are present on the red cells of an AB patient. H antigen is a precursor to the ABO
antigens.

QUESTION 3
Which of the following media would you use to isolate Francisella tularensis:
[A] Sheep-blood agar
[B] Lowenstein-Jensen media
[C] Bordet-Gengou media
[D] Cysteine-blood agar.
Answer: D;
Although cysteine-blood agar was traditionally used, F. tularensis will also grow on commercially available
Thayer-Martin and chocolate agar which have been enriched with supplemental nutrients.
QUESTION 4
The presence of hyaline, septate hyphae, and a young conidiophore with a foot cell and
a swollen vesicle in a fungus culture are excellent clues indicative of:
[A] Acremonium
[B] Aspergillus
[C] Paecilomyces
[D] Penicillium
[E] Scopulariopsis.
Answer: B;
The presence of hyaline, septate hyphae, and a young conidiophore with a foot cell and a swollen vesicle in a
fungus culture are excellent clues indicative of Aspergillus. Aspergillus has the ability to infect primarily
immunocompromised hosts, and causes pneumonia and/or disseminates to other organs. Clinical specimens
should be inoculated onto primary isolation media, such as Sabouraud's dextrose agar. Aspergillus spp. are
fast growing and can be white, yellow, yellow-brown, brown to black or green in color.
