Which symptom is NOT associated with a reaction to blood transfusion?

1. Hypotension

2. Blood in urine

3. Increased blood pressure

4. Hyperthermia

The correct answer is: Increased blood pressure

In the context of blood transfusion reactions, it is important to recognize the various symptoms that can occur. Symptoms such as hypotension, blood in urine, and hyperthermia are commonly associated with adverse reactions to transfusions. Hypotension, or low blood pressure, can occur as a result of a transfusion reaction, particularly in cases like acute hemolytic reactions. Blood in the urine, or hematuria, can indicate damage to the kidneys or urinary tract caused by antigen-antibody reactions affecting red blood cells. Hyperthermia, or elevated body temperature, can also manifest as a response to the transfused blood, particularly in febrile non-hemolytic transfusion reactions. In contrast, the presence of increased blood pressure is not typically associated with a transfusion reaction. Instead, transfusion reactions usually lead to a decrease in blood pressure due to fluid shifts and shock in severe cases. Understanding these symptoms helps healthcare professionals monitor patients effectively during and after blood transfusions, ensuring quick identification and management of any adverse reactions.
