May-Hegglin anomaly is a rare autosomal dominant condition in which patients are at risk for bleeding and infections. It is characterized by the presence of large Dohle body like inclusions within neutrophils, eosinophils, basophils, and monocytes.
The WBC anomaly indicated by the arrow in this illustration is:

• A.Pelger-Huet anomaly
• B.May-Hegglin anomaly
• C.Toxic granulation
• D.Alder-Reilly anomaly

In healthy individuals, procalcitonin is only synthesized by the thyroid C cells. In bacterial infections, PCT is synthesized in various extrathyroidal neuroendocrine tissues.
In healthy individuals, procalcitonin is synthesized by which cells in the body?

• A.Hepatocytes
• B.Red blood cells
• C.Thyroid C cells
• D.Leukocytes

Rapid vascular constriction, not dilation, immediately occurs when there is vascular injury in order to constrict the amount of blood that escapes the vessels; ultimately preventing massive loss of blood.
Primary hemostatic processes resulting from vascular damage include all of the following EXCEPT:

• A.collagen activates glycoprotein IIb/IIIa during platelet activation
• B.platelet granule release and fibrinogen mediate platelet aggregation
• C.von Willebrand factor mediates platelet adhesion
• D.b & c
• E.rapid and immediate vascular dilation occurs

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.Direct Antiglobulin Test (DAT)
• B.Antibody screen on recipients serum
• C.ABO and Rh typing of recipient
• D.Major crossmatch or computer crossmatch

On the red cell membrane, there is a bicarbonate / chloride exchanger. This exchanger allows for bicarbonate to leave the red cells while chloride is allowed inside.
In blood, bicarbonate leaves the red blood cell and enters the plasma through an exchange mechanism with:

• A.phosphorus
• B.chloride
• C.sodium
• D.potassium
