Final answer:
A hemolytic transfusion reaction occurs when there is a mismatch between the recipient's antibodies and the donor's red blood cells (RBCs), leading to the destruction of transfused RBCs. Symptoms include fever, chills, itching, hives, difficulty breathing, hemoglobin in the urine, and low blood pressure.
Step-by-step explanation:
A hemolytic transfusion reaction occurs when there is a mismatch between the recipient's antibodies and the donor's red blood cells (RBCs). This can happen if the recipient has antibodies against the donor's blood type antigens. Incompatible transfusions can trigger an immune response, resulting in the destruction of transfused RBCs. The signs and symptoms of a hemolytic transfusion reaction can include fever, chills, itching, hives, difficulty breathing, hemoglobin in the urine, and low blood pressure. In severe cases, it can lead to shock, multi-organ failure, and even death.
