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 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: 2 g/dL

• Hematocrit: 3%, Hemoglobin: 1 g/dL

• Hematocrit: 4%, 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, review of blood bank records, antibody screening, crossmatch, blood product inspection

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

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 with patient information

• Labeling blood sample tubes with only the patient's first name

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, signature of phlebotomist

• First name of recipient, unique identification number, date of collection, signature of phlebotomist

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

Which type of sample is preferred for compatibility testing?

• Serum

• Plasma

• Whole blood

• Red blood cells

What is the age limit for a blood sample used in compatibility testing?

• 1 day

• 3 days

• 7 days

• 14 days

Why is it important to store patient samples and donor unit segments after transfusion?

• To prevent sample mix-up

• To investigate transfusion reactions

• To perform additional testing

• To ensure proper documentation

What is the purpose of antibody screening in compatibility testing?

• To prevent transfusion reactions

• To detect donor units unlikely to survive once transfused

• To provide a working measure of successful transfusion

• To detect clinically significant antibodies
