A client expresses anxiety and fear about receiving a blood transfusion. What action should the nurse take to address the client's concerns?

A) Incorrect: Discontinuing the blood transfusion may be necessary if the allergic reaction is severe, but it is not the appropriate action for a mild allergic reaction. The nurse should manage the current reaction and take preventive measures for future transfusions.

B) Incorrect: Administering an antihistamine is appropriate to manage the current allergic reaction,but it may not prevent future allergic reactions. The nurse should focus on preventing allergic reactions in future transfusions.

C) Incorrect: Notifying the healthcare provider is important for appropriate management, but it may not directly prevent future allergic reactions. The nurse should implement preventive measures.

D) Correct: Obtaining a sample for repeat crossmatching is essential to identify and select blood products that are less likely to cause an allergic reaction in the client. This step can help prevent future allergic transfusion reactions and ensure safer blood product selection.

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.
