A patient's blood type is AB positive. Which donor blood type can they receive for red blood cell transfusions?
Answer: Any ABO and Rh type
AB positive patients are universal recipients for red blood cells because they have no anti-A, anti-B, or anti-Rh antibodies.
Cryoprecipitate is PRIMARILY indicated for which coagulation deficiency?
Answer: Factor VIII and fibrinogen deficiency
Cryoprecipitate is rich in fibrinogen, Factor VIII, Factor XIII, von Willebrand factor, and fibronectin, making it the treatment of choice for fibrinogen and Factor VIII deficiencies.
A nurse notices a patient's urine has turned bright red during a blood transfusion. After stopping the transfusion, what is the NEXT priority nursing action?
Answer: Notify the physician and blood bank immediately
Hemoglobinuria (red urine during transfusion) signals acute hemolysis; the nurse must immediately notify the physician and blood bank and return the blood bag for analysis.
When administering granulocytes, the nurse should anticipate that infusion should be completed within what timeframe?
Answer: 1 hour
Granulocytes have a very short shelf life and must be infused within 1 hour of receipt because they rapidly lose viability at room temperature.
Which documentation is MANDATORY before initiating a blood transfusion per CRNI standards?
Answer: Two-nurse verification of patient identity and blood product compatibility
Two-nurse independent verification of patient identity (two identifiers) against the blood product label and crossmatch report is a mandatory safety check before transfusion.
A patient develops urticaria and pruritus during the first 15 minutes of a platelet transfusion but has no fever, hypotension, or respiratory distress. What is the BEST initial action?
Answer: Stop the transfusion, administer diphenhydramine, and restart if symptoms resolve
Mild allergic reactions (urticaria only) can be managed by stopping the transfusion, administering antihistamine, and restarting if symptoms resolve within 15-30 minutes.
Massive transfusion protocol (MTP) is typically activated when a patient requires more than how many units of PRBCs within 24 hours?
Answer: 10 units
Massive transfusion is defined as transfusion of 10 or more units of PRBCs within 24 hours, triggering MTP to address coagulopathy and hypothermia.
