Which of the following could indicate a reaction to the transfusion?

The correct answer indicates that both increased heart rate and decreased blood pressure can be symptoms associated with a reaction to a blood transfusion. When a transfusion is performed, the body may react to the foreign blood components, leading to various physiological changes.

An increased heart rate can occur as the body's response to stress or discomfort caused by the transfusion reaction. The heart pumps faster in an attempt to maintain adequate blood flow and oxygen delivery to tissues, especially if there are signs of distress or inadequate perfusion.

Similarly, decreased blood pressure can also be a critical indicator of transfusion reactions, particularly if the reaction involves an allergic response or anaphylaxis. In these cases, vasodilation (widening of blood vessels) can occur, leading to a drop in blood pressure as the body struggles to compensate for the sudden changes in blood volume and composition.

Both symptoms are important for healthcare providers to monitor closely during and after transfusions, as they may suggest that the patient is experiencing a significant reaction that requires immediate attention. Recognizing these signs can help ensure timely intervention and improve patient safety.

In summary, an increased heart rate coupled with decreased blood pressure effectively captures the potential physiological responses to an adverse transfusion reaction, making the choice encompassing both symptoms the
