What is a common sign of a transfusion reaction?

• A. Increased heart rate
• B. Low back pain
• C. Increased blood pressure
• D. High fever

Answer: (B)

Low back pain is a recognized sign of a transfusion reaction due to the location of the kidneys and the anatomical changes that occur during a reaction. When a patient experiences a hemolytic transfusion reaction, typically an immune response, the body reacts to the transfused blood as a foreign substance. This can lead to damage to the kidneys, which are situated in the lower back, and as a result, pain may be referred to this area. In many cases, this symptom serves as an early indicator to healthcare providers that a reaction may be occurring, prompting further assessment and intervention. Timely recognition of these symptoms is crucial to ensure patient safety and appropriate treatment. Other common signs of transfusion reactions can vary, but low back pain stands out due to its anatomical significance and direct correlation with kidney involvement during adverse reactions.
