Blood Banking

What is the primary purpose of compatibility testing in blood banking?

• To prevent life-threatening transfusion reactions

• To maximize in vivo survival of transfused red cells

• To detect clinically significant antibodies

• To determine the efficacy of transfusion

What is the purpose of the crossmatch in compatibility testing?

• To prevent transfusion reactions

• To detect donor units unlikely to survive normally once transfused

• To provide a working measure of successful transfusion

• To check the results of the antibody screen

What is the expected increase in hematocrit and hemoglobin levels after transfusing one unit of RBCs?

• Hematocrit: 1%, Hemoglobin: 1 g/dL

• Hematocrit: 2%, Hemoglobin: 1 g/dL

• Hematocrit: 3%, Hemoglobin: 1 g/dL

• Hematocrit: 3%, Hemoglobin: 2 g/dL

What are the steps involved in compatibility testing?

• Accurate patient identification, sample collection, antibody screening, crossmatch, blood product inspection

• Patient identification, sample labeling, antibody screening, crossmatch, blood product tagging

• Patient identification, sample collection, antibody screening, crossmatch, blood product inspection

• Accurate patient identification, sample labeling, antibody screening, crossmatch, blood product tagging

What is the recommended practice for patient identification during blood sample labeling?

• Labeling blood sample tubes in the presence of the patient

• Labeling blood sample tubes in the absence of the patient

• Labeling pre labeled tubes in the presence of the patient

• Labeling pre labeled tubes in the absence of the patient

What information should be included on the label of a blood sample tube?

• First and last name of recipient, date of collection, signature of phlebotomist

• First and last name of recipient, unique identification number, date of collection

• First and last name of recipient, unique identification number, signature of phlebotomist

• First and last name of recipient, date of collection, initials of phlebotomist

Which type of tubes are most commonly used for collecting patient samples for compatibility testing?

• Plain tubes with a red top

• Plain tubes with a purple top

• Plain tubes with a pink top

• Plain tubes with a green top

Why is it important to consider the age of the sample in compatibility testing?

• To ensure accurate patient identification

• To prevent sample mix-up

• To detect clinically significant antibodies

• To determine the efficacy of transfusion

How long should patient samples be stored following transfusion?

• 3 days

• 5 days

• 7 days

• 10 days

What is the purpose of ABO and D phenotyping in compatibility testing?

• To prevent transfusion reactions

• To detect donor units unlikely to survive normally once transfused

• To provide a working measure of successful transfusion

• To determine the recipient's blood type
