KROK 1 2009 – Question 193 · KROK (Medicine) · Physiology
It was established that agglutination of the recipient’s blood erythrocytes had been caused by the standard sera from the I and II groups. Serum from the III group as well as anti-Rh serum hadn’t provoke any agglutination. Which blood group and rhesus is allowed to be transfused this recipient?
- A. AB (IV ), Rh−
- B. 0, α, β, (I) Rh+
- C. B, α (III) Rh−
- D. A, β (II) Rh−
- E. AB (IV ), Rh+
Hint
Deduce the red-cell antigens from the sera that caused agglutination and from the absence of a reaction with the rest, and then choose a blood that the recipient's own plasma will not attack.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
