Which symptom is least likely associated with a hemolytic reaction?

A hemolytic reaction occurs when there is an immune response against transfused blood cells, typically due to blood type incompatibility. This reaction can lead to a variety of symptoms as the body reacts to the destruction of red blood cells.

Joint pain, while it can be uncomfortable, is not a typical symptom of a hemolytic reaction, as the primary symptoms are generally more systemic and related to the body's acute response to hemolysis. Common symptoms of a hemolytic reaction include fever, chills, oliguria (reduced urine output due to acute kidney injury from hemolysis), increased pulse and respiratory rates due to stress on the body, and shivering as the body attempts to regulate its temperature in response to a reaction.

In contrast, oliguria is directly related to kidney involvement due to the breakdown of red blood cells and can indicate serious complications, shivering often accompanies blood transfusion reactions as the body may experience chills from an immune response, and increased pulse and respirations reflect the body's heightened state during stress from the reaction.
