Title: 036Quiz

Q: Select from the following choices all recipients who would be compatible with a group A plasma transfusion.
- Blood group AB
- Blood group A (correct)
- Blood group O (correct)
- Blood Group B

Fill in the missing words in the sentence below:

Q: If using group A plasma for trauma transfusion in those of unknown blood type, approximately [...]% of recipients are likely incompatible, specifically those with blood groups [...] and [...].
A: 15/15%; B/AB; AB/B

Drag the words into the correct boxes

Q: The most uncommon ABO group is [...], seen in approximately 4% of the population. Meanwhile, group [...] is seen in 45% of those of European origin, group [...] in 40%, and group [...] in 11%.
A: AB; O; A; B

Q: TRUE OR FALSE: Most transfusion services responding to a recent survey about trauma transfusion limited the number of group A plasma units that could be given to a trauma patient in order to reduce the risk of hemolysis.
A: false
If right: Good! According to Dr. Dunbar's survey published in 2015 (see link below), most hospitals do not limit the amount of group A plasma given in trauma.
If wrong: Sorry, it's actually a FALSE statement! According to Dr. Dunbar's survey published in 2015 (see link below), most hospitals do not limit the amount of group A plasma given in trauma.

Q: Which of the following is TRUE regarding the transfusion of group A plasma to group B or AB patients in trauma, according to the two studies authored by Drs Dunbar and Stevens?
- Group B patients receiving group A plasma had no impact on mortality, but group AB patients were more likely to die in the hospital (This statement is not true. The impact was the same for group B and AB.)
- These patients had more in-hospital morbidity (e.g., sepsis, hemolysis), but no increase in mortality (This statement is not true. There was no impact on morbidity OR mortality.)
- Both B and AB patients had episodes of hemolysis, with increased in-hospital mortality (This statement is not true. There was no hemolysis and no increase in mortality.)
- These patients had no increase in morbidity or mortality over those who did not receive incompatible plasma units (correct) (Good! This is the true statement.)
- Only group B or AB patients receiving plasma with high titers of anti-B showed risk of hemolysis (This statement is false. First, there was no evidence of hemolysis in any group B or AB patient. Second, the vast majority of those transfusing group A plasma do not perform titers, so how many received "high-titer" anti-B is unknown.)
