Modern Blood Banking Study Set 1

Which red blood cell morphology is most characteristic in ABO HDFN and absent in Rh HDFN?

In HDFN, the IgG antibodies are directed against which antigen on the fetal red blood cells?

Why is suppression of erythropoiesis an advantage of exchange transfusions?

Immunization of the mother can be caused by as little as D-positive fetal cells.

Which of the following treatments uses ultraviolet light to treat hyperbilirubinemia after the infant is delivered?

All of the following are goals of an exchange transfusion except:

What tests are indicated for cord blood specimens if the mother has made anti-K?

What is the physiological mechanism of Rh-immune globulin?

An O-positive mother gave birth to an A- negative baby. After 24 hours the newborn's bilirubin level rose to 18 mg/dL. A DAT performed on the cord blood specimen was positive with polyspecific AHG and anti-IgG reagents. It is probable that from maternal circulation is coating the newborn's red blood cells.

Which of the following best describes the principle of the Kleihauer-Betke test?

Why is the immediate spin eliminated in the prenatal antibody screen?

Active immunization induced by Rh(D) antigen can be prevented by the concurrent administration of:

Which severe outcome can be caused by indirect bilirubin levels greater than 18 mg/dL in the newborn?

Why is reverse grouping omitted in neonate ABO grouping?

Which of the following reagents can be used to determine the immunoglobulin class of anti-M?

Due to a short supply of O-negative packed cells, an Rh-negative patient was transfused with 1 unit of Rh-positive red blood cells. Calculate the number of Rh-immune globulin vials needed to protect against 250 mL of Rh-positive packed cells.

A 300-µg dose of Rh-immune globulin contains sufficient anti-D to protect against how much whole blood?

How is an intrauterine transfusion performed?

All of the following are characteristic of ABO hemolytic disease of the fetus and newborn (HDFN) except:

A cord blood specimen from a jaundiced infant should be tested for which of the following?
