Final answer:
Transfusion-related complications include severe immunologic reactions like alloimmunization and hemolytic transfusion reaction, as well as transmission of infections such as CMV due to immunosuppression.
Step-by-step explanation:
When considering transfusion-related complications, the correct answer is that they include infection transmission, alloimmunization, and immunohematologic reactions. Blood transfusions are critical medical procedures where compatibility between donor and recipient blood is essential to prevent adverse reactions. Transfusion of incompatible blood can lead to a type II hypersensitivity reaction, also known as a hemolytic transfusion reaction (HTR), which is a serious and potential life-threatening event. Symptoms can include fever, chills, itching, hives, and in severe cases, hypotension, shock, or even death. It's imperative to match patient-donor blood types to prevent these transfusion reactions. Furthermore, some patients may become infected with CMV due to immunosuppression caused by transfusions or organ transplants, which can also lead to serious health issues.
