• Question 41:

  Convert the following temperature from Celsius to Fahrenheit

  8 degrees C

  A. 77 degrees F

  B. 68 degrees F

  C. 46.4 degrees F

  D. 14 degrees F

  Correct Answer: C

• Question 42:

  Granulocytes are the most granular population; they have the most side scatter of the cell populations that are listed.

  Which of these white blood cell populations would have the MOST side scatter when analyzed using flow cytometry?

  A. Monocytes

  B. Lymphocytes

  C. Granulocytes

  Correct Answer: C

• Question 43:

  AABB Standards do not require a DAT, autologous control, or a minor crossmatch for pretransfusion testing.

  Essential components of compatibility testing include all of the following except :

  A. Antibody screen on recipients serum

  B. Major crossmatch or computer crossmatch

  C. ABO and Rh typing of recipient

  D. Direct Antiglobulin Test (DAT)

  Correct Answer: D

• Question 44:

  Iron deficiency anemia, or IDA, is associated with an increased TIBC as there is less iron to bind to transferrin. Microcytic, hypochromic red cell morphology, a decreased serum iron level, a decreased serum ferritin level, and a decreased hemoglobin level are all characteristics associated with IDA.

  All of the following are characteristic findings in patients with iron deficiency anemia EXCEPT:

  A. microcytic, hypochromic red cell morphology

  B. decreased serum iron level

  C. decreased total iron-binding capacity (TIBC)

  D. decreased ferritin

  E. decreased hemoglobin

  Correct Answer: C

• Question 45:

  Serum ferritin is a good indicator of iron deficiency. However, it acts like an acute phase reactant, being elevated in a large number of conditions. Patients who have iron deficiency as well as another condition that elevates serum ferritin levels may therefore have normal or even elevated serum ferritin levels.

  Which one of the following statements about serum ferritin are true:

  A. It is a sensitive indicator of iron deficiency

  B. Elevation of serum ferritin is specific for hemochromatosis

  C. It is synonymous with transferrin

  D. It is a better test for bone marrow iron stores than a Prussian blue stain of marrow particles

  Correct Answer: A

• Question 46:

  The thrombin time (TT) involves the addition thrombin to platelet poor plasma to stimulate the clotting process. It reflects ability of the patient to convert fibrinogen to fibrin but is also sensitive to the presence of inhibitors that may be present in the plasma, like heparin. Therefore, it can be used to measure the effects of heparin on a coagulation sample.

  This assay would be used to help rule-out heparin contamination in a coagulation sample:

  A. Protein C assay

  B. Thrombin time

  C. PT

  D. APTT

  Correct Answer: B

• Question 47:

  Patients with antibody to the following antigen are immune to Hepatitis B:

  A. Core antigen

  B. Surface antigen

  C. antigen

  D. Delta antigen

  Correct Answer: B

• Question 48:

  Glycoprotein IIb/IIIa is integral in the process of platelet aggregation as well as clot retraction.

  A defective clot retraction might be caused by which one of these?

  A. Lack of or defect of platelet receptor glycoprotein Ib

  B. Lack of or defect of platelet receptor Ilb/IIIa

  C. Insufficient storage of ADP in platelet granules

  D. Absence or defect of von Willebrand's factor

  Correct Answer: B

• Question 49:

  Ammonium biurate crystalsare typically round, irregularly spiked and yellow-brown in color.

  A microscopic examination of a normal urine pH 8.0 shows 2+ yellow-brown thorny spheres which are MOST probably: A. ammonium biurate crystals

  B. ampicillin crystals

  C. amorphous urate crystals

  D. crenated red cells

  E. waxy casts

  Correct Answer: A

• Question 50:

  What amount of absorbent material must be included between the primary receptacle and secondary packaging for either a category A or category B liquid specimen?

  A. At least enough to surround the primary receptacle

  B. Enough to completely absorb the specimen if the container leaked or broke

  C. Enough to fill the space between the primary receptacle and the secondary container

  D. There is no requirement for absorbent material

  Correct Answer: A
