7 Blood Banking

What is the second most important test to complete in blood banking?

• Crossmatching

• Antibody screen

• Compatibility testing

• Autologous blood

What should be done if a positive reaction is noted during the antibody screen?

• Initiate antibody identification procedures

• Initiate antiglobulin crossmatches

• Initiate both antibody identification procedures and antiglobulin crossmatches

• Initiate compatibility testing

According to AABB, what is the risk of transfusing an incompatible unit compared to the risk of depriving the patient of oxygen-carrying capacity?

• The risk of transfusing an incompatible unit is greater

• The risk of depriving the patient of oxygen-carrying capacity is greater

• The risks are equal

• There is no risk involved

What information must be included in the detailed records of emergency release of blood products?

• Patient's full name and unique identifiers

• ABO and D phenotype

• List of all issued units

• All of the above

What is the definition of a massive transfusion?

• Transfusion of blood products within a 24-hour period

• Transfusion of blood products in an infant patient

• Transfusion of blood products in an adult patient

• Total volume exchange of blood through transfusion within a 24-hour period

What does it mean when an antibody is passively transfused?

• The antibody is transferred from the recipient to the plasma portion of a blood product

• The antibody is transferred from the donor to the recipient during transfusion

• The antibody is transferred from the plasma portion of a blood product to the recipient

• The antibody is transferred from the recipient to the donor during transfusion

What is the purpose of crossmatching autologous blood?

• To ensure compatibility between the donor and recipient

• To locate and transfuse autologous units to the intended recipient

• To prevent the transfer of antibodies from the donor to the recipient

• To determine the ABO and D phenotype of the donor

At what age do infants begin producing their own ABO antibodies?

• At birth

• At 4 to 6 months

• At 1 year

• At 2 years

Which blood components do not need to be crossmatched?

• Plasma, platelet concentrates, and cryoprecipitate

• Apheresis platelets and granulocyte concentrates

• Plasma and platelet concentrates

• Cryoprecipitate and granulocyte concentrates

What is the purpose of cryoprecipitate?

• To provide oxygen-carrying capacity

• To prevent infection

• To promote blood clotting

• To increase platelet count
