A patient develops sudden hypotension, back pain, and hemoglobinuria minutes after starting a transfusion. What is the most likely reaction?
Answer: Acute hemolytic transfusion reaction
These signs indicate an acute intravascular hemolytic reaction, usually from ABO incompatibility.
Transfusion-related acute lung injury (TRALI) is characterized by which finding?
Answer: Non-cardiogenic pulmonary edema within 6 hours of transfusion
TRALI presents as acute non-cardiogenic pulmonary edema within 6 hours of transfusion.
Which patients require irradiated cellular blood products to prevent transfusion-associated graft-versus-host disease?
Answer: Severely immunocompromised and intrauterine transfusion recipients
Irradiation prevents TA-GVHD in immunocompromised and fetal/neonatal recipients.
A delayed hemolytic transfusion reaction most often results from an anamnestic response to which antibody type?
Answer: Kidd (anti-Jka) antibodies
Kidd antibodies notoriously drop below detection and cause delayed reactions on re-exposure.
What is the expected corrected count increment purpose when transfusing platelets?
Answer: To assess platelet transfusion response and detect refractoriness
The corrected count increment evaluates the platelet response and identifies refractoriness.
Which anticoagulant-preservative allows RBC storage for up to 42 days?
Answer: CPDA-1 with additive solution (AS)
Additive solutions extend RBC storage to 42 days.
A patient with a history of anaphylactic transfusion reactions and undetectable IgA most likely needs which product?
Answer: Washed or IgA-deficient components
IgA-deficient patients with anti-IgA require washed or IgA-deficient components.
