A client with blood type B-positive (B+) requires a blood transfusion. Which blood types are compatible with this client for a crossmatch?

A: Notify the healthcare provider immediately to obtain a blood transfusion order – This is the priority action because the client’s hemoglobin level of 8 g/dL, along with symptoms of hypoxia, indicates a need for urgent medical intervention. Obtaining an order for a transfusion is crucial for addressing the underlying issue of low hemoglobin and associated hypoxia.
B: Administer supplemental oxygen to the client to improve oxygenation – While this action is important, it is not the first step. The low hemoglobin indicates a need for a transfusion, and notifying the provider can lead to quicker treatment.
C: Initiating IV access with a large-bore catheter is an important step in preparation for a possible blood transfusion, but it is not the first action. The client's current symptoms must be managed promptly.
D: Ambulation may be contraindicated post-major surgery, especially when the client is symptomatic. It could exacerbate the client's condition and is not the immediate priority in this scenario.

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.
