Question

In rare cases, this process can be induced by repetitive motions like playing the bongos or marching. A disease caused by this process can be identified with the Liley (“LYE-lee”) chart, which plots changes in optical density at 450 nanometers. This process names a disease with “cold” and “warm” types, respectively mediated by IgM (10[1])(“I-G-M”) and (10[1])IgG (“I-G-G”). In differential diagnosis, this process (10[1])is confirmed by labs with elevated LDH, decreased haptoglobin, and elevated reticulocyte (-5[1])count. This process names a “disease of the newborn” that can be identified by agglutination (10[1])in the direct Coombs test. This process can cause prehepatic (“pre-huh-PAT-ick”) jaundice by triggering autoimmune activation of the (-5[1])complement system. Rh-positive babies born (-5[1])to Rh-negative mothers experience (-5[1])this process’s namesake form of anemia. For 10 points, name this process that kills (-5[1])red blood cells (10[1]-5[2])by rupturing (10[1])their (-5[1])membranes. (10[2])■END■ (10[11]0[6])

ANSWER: hemolysis (“hee-MAWL-uh-siss”) [accept (autoimmune) hemolytic anemia or hemolytic disease of the newborn; prompt on cell lysis; prompt on anemia until read by asking “caused by what process?”; prompt on cold agglutination or autoagglutination until “agglutination” is read by asking “what process does it precede?”; prompt on alloimmunization or isoimmunization by asking “what process is triggered by the antibodies?”]
