A nurse is caring for a client who develops urticaria (hives) and itching during a blood transfusion. The nurse suspects an allergic transfusion reaction. What is the appropriate nursing action?

A) Correct: Pre-medicating the client with antihistamines before the transfusion can help prevent or minimize allergic transfusion reactions in clients with a history of severe allergies. Antihistamines block histamine release, reducing the risk of allergic symptoms.

B) Incorrect: Administering the blood transfusion rapidly is not a preventive measure for allergic transfusion reactions. In fact, rapid administration may increase the risk of adverse reactions.

C) Incorrect: Warming the blood product before administration is important to prevent hypothermia but is not directly related to preventing allergic transfusion reactions.

D) Incorrect: Monitoring the client's vital signs during the transfusion is a standard practice, but it is not the primary intervention for preventing allergic transfusion reactions. Pre-medication with antihistamines is a more targeted approach.

A) Obtaining the client's informed consent is a critical step before any medical procedure, including blood transfusions. This ensures the client understands the risks and benefits of the transfusion and gives their consent willingly.

B) Confirming the client's blood type and Rh factor with the blood bank is essential to prevent transfusion reactions. Mismatching blood types can lead to severe transfusion reactions and is a crucial step in the transfusion process.

C) Administering pre-medication to prevent transfusion reactions is not a standard practice. However, the nurse should assess the client for any risk factors or history of previous transfusion reactions to take appropriate precautions.

D) Assessing the client's blood pressure and heart rate is an important part of the overall assessment before the blood transfusion.
