A nurse is monitoring a patient who is receiving a blood transfusion.
Which of the following symptoms should the nurse report to the charge nurse as a sign of an allergic blood transfusion reaction?
A.
Bilateral flank pain.
B.
Distended jugular veins.
C.
Generalized urticaria.
D.
Blood pressure 184/92 mm Hg.
The Correct Answer and Explanation is:
The correct answer is C. Generalized urticaria.
Explanation:
A blood transfusion can be a life-saving intervention, but it carries the risk of complications, including allergic reactions. Allergic reactions to blood transfusions are usually mild, but they can range from mild symptoms such as hives (urticaria) to more severe reactions like anaphylaxis.
Generalized urticaria refers to widespread hives or itchy red welts on the skin. This is one of the most common signs of an allergic reaction during a blood transfusion. Urticaria occurs when the body recognizes certain proteins in the donor blood as foreign, triggering an immune response. This immune response causes histamine and other chemicals to be released, leading to symptoms like hives, itching, and sometimes swelling.
Other signs of an allergic reaction during a blood transfusion may include:
- Itching
- Swelling, especially of the face or throat
- Flushing
- Difficulty breathing (in more severe cases)
When a nurse notices these symptoms, it is crucial to report them immediately to the charge nurse and stop the transfusion. The transfusion should be paused while the healthcare team assesses the patient and determines if the reaction is mild or if it requires treatment with antihistamines, steroids, or other interventions.
Explanation of other options:
- A. Bilateral flank pain: This symptom is more indicative of a hemolytic transfusion reaction, which occurs when the immune system attacks the transfused red blood cells, causing them to rupture. It can lead to serious complications, including kidney damage. Although this is an urgent condition, it is not typically associated with an allergic reaction.
- B. Distended jugular veins: This is a sign of circulatory overload, which can occur when the patient receives too much blood or fluids too quickly. This causes excess volume in the circulatory system and is unrelated to an allergic reaction.
- D. Blood pressure 184/92 mm Hg: Elevated blood pressure might indicate circulatory overload or other cardiovascular issues but is not specifically related to an allergic transfusion reaction.
In summary, generalized urticaria is a clear indication of an allergic reaction during a blood transfusion, and recognizing this early is essential to managing the reaction and preventing more severe complications.
