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

A) Incorrect: Fever and chills during a blood transfusion may be signs of a febrile transfusion reaction, not an allergic reaction. The nurse should provide information specific to preventing allergic reactions.

B) Correct: Itching, rash, and facial swelling are common signs of an allergic transfusion reaction. The nurse should instruct the client to notify the healthcare provider immediately if they experience these symptoms.

C) Incorrect: A brief period of increased heart rate after the transfusion may be normal, but it is not specific to preventing an allergic transfusion reaction. The nurse should focus on providing information about allergic reaction symptoms.

D) Incorrect: Lower back pain is not typically associated with allergic transfusion reactions. The nurse should provide information about symptoms that indicate an allergic reaction, such as itching, rash, and facial swelling.

A) Correct: Red blood cells are the main blood component involved in the crossmatching process. Crossmatching ensures compatibility between the donor's red blood cells and the recipient's plasma, preventing adverse reactions during the transfusion.

B) Incorrect: White blood cells are not part of the crossmatching process. They play a role in the immune response but are not specifically assessed during crossmatching.

C) Incorrect: Platelets are not directly involved in the crossmatching process. Crossmatching primarily focuses on red blood cell compatibility.

D) Incorrect: Plasma is not directly involved in the crossmatching process. The focus is on ensuring compatibility between red blood cells and the recipient's plasma.
