A) R1r (CDe/cde) B) R2R2 (cDE/cDE) C) R1R2 (CDe/cDE) D) rr (cde/cde) You don’t have time to write out all the haplotypes. You must know that the presence of C and E without c or e suggests a compound heterozygote. (Answer: C – R1R2). 2. The "Crossmatching Crisis" (Problem Solving) These simulate the 2 AM emergency where the blood fridge is empty.
So, the next time you sit down with a practice exam, don't groan. Treat it like a blood bank refrigerator full of puzzles. Crack the code, find the compatible unit, and keep the patient safe. Multiple Choice Questions And Answers In Immunohematology
A patient’s red cells are positive with Anti-D, Anti-C, and Anti-E, but negative with Anti-c and Anti-e. What is the most probable Rh genotype? A) R1r (CDe/cde) B) R2R2 (cDE/cDE) C) R1R2
Why MCQs are more than just memorization—they are the frontline of patient safety. If you’ve ever spent a late night staring at a test tube (or a computer screen) trying to figure out why an ABO discrepancy exists, you know that Immunohematology—or “Blood Banking” as the cool kids call it—is not for the faint of heart. It is a field where a single agglutination reaction can mean the difference between a life-saving transfusion and a fatal hemolytic reaction. Treat it like a blood bank refrigerator full of puzzles
A group O patient with a history of multiple transfusions requires an emergency transfusion. The antibody screen is positive, and the identification panel reveals Anti-Jka. All Jka-negative units are O positive. However, the patient types as Group O, Rh negative. What is the best course of action?
