What is the maximum infusion time allowed for one unit of packed red blood cells?
Answer: 4 hours
Packed red blood cells must be infused within 4 hours of removal from controlled storage to minimize bacterial proliferation risk.
Which type of blood component requires irradiation before transfusion to immunocompromised patients?
Answer: Granulocyte concentrates
Granulocyte concentrates and other cellular blood products require irradiation to prevent transfusion-associated graft-versus-host disease in immunocompromised patients.
During a platelet transfusion, the patient develops rigors and a temperature increase of 1.5 degrees C. What is the MOST likely cause?
Answer: Febrile non-hemolytic transfusion reaction
Febrile non-hemolytic transfusion reactions are the most common reaction with platelet transfusions, characterized by fever and rigors without hemolysis.
What is the correct blood sample labeling requirement for pre-transfusion testing?
Answer: Labels with patient name, MRN, date, time, and collector's initials applied at the bedside
Pre-transfusion specimens must be labeled at the bedside with complete patient identifiers, date, time, and phlebotomist identification to prevent specimen misidentification.
Which IV solution is compatible for co-infusion with blood components?
Answer: 0.9% Normal saline
Only 0.9% normal saline is compatible with blood component administration. Other solutions can cause hemolysis or clotting.
A patient with a history of allergic transfusion reactions is ordered packed RBCs. What premedication is typically administered?
Answer: Diphenhydramine 25-50 mg IV
Diphenhydramine is the standard premedication for patients with a history of allergic transfusion reactions, given 30 minutes before transfusion to prevent urticaria and itching.
