Which vital sign should be monitored closely during a blood transfusion for signs of an adverse reaction?

• A. Blood pressure
• B. Heart rate
• C. Temperature
• D. Respiratory rate

Answer: (C)

Monitoring the temperature during a blood transfusion is crucial because a rise in temperature can be an early indicator of a transfusion reaction, particularly febrile non-hemolytic reactions. These reactions often occur when the recipient's immune system responds to white blood cells or cytokines in the donated blood. A temperature increase may be one of the first signs, making it key to identify and address potential complications early on. In addition to temperature, other vital signs are monitored, but temperature is specifically significant in the context of transfusion reactions. Typically, health care providers will routinely check the patient’s temperature before, during, and after the transfusion. While blood pressure, heart rate, and respiratory rate are important in assessing the overall status of the patient during a transfusion, an elevated temperature is a direct sign of a potential adverse reaction and requires immediate attention.
