Which symptom combination is associated with an acute hemolytic transfusion reaction?

• A. Nausea with fever only
• B. Rash with joint pain
• C. Back pain only
• D. Arm pain, chest pain, back pain, nausea, DIC, and fever

Answer: (D)

Acute hemolytic transfusion reaction happens when donor red cells are destroyed by the recipient’s immune system, causing intravascular hemolysis and a cascade of systemic effects. The destruction of red cells releases products that irritate the body and can trigger widespread inflammation, pain, fever, and potential coagulopathy. The most characteristic and alarming presentation includes multiple pain sites (arm at the IV access, chest, and back) along with nausea, fever, and signs of coagulation disturbance such as disseminated intravascular coagulation. This combination reflects the severe, systemic impact of massive hemolysis, not just a localized or milder reaction. Other symptom patterns tend to align with less severe or different transfusion reactions, such as fever with nausea alone or an allergic-type rash, which don’t embody the full, critical picture of acute hemolysis.
