Red blood cells.

White blood cells.

Platelets.

Plasma.

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is C

Explanation

A) Incorrect: Slowing down the transfusion rate is not the appropriate action in this scenario. The client is experiencing signs of an allergic reaction, and the nurse must act promptly to address the situation.

B) Incorrect: Elevating the client's feet and lowering the head (Trendelenburg position) is not indicated for an allergic reaction. It may be used for clients in shock, but the priority is to manage the allergic reaction.

C) Correct: The nurse should immediately discontinue the transfusion and initiate the infusion of normal saline to maintain the client's intravascular volume. Discontinuing the blood transfusion helps prevent further exposure to the allergen (if an allergic reaction is confirmed) and addresses fluid volume needs.

D) Incorrect: While administering an antihistamine may be part of the treatment plan for an allergic reaction, it is not the immediate action. The nurse should first discontinue the transfusion and infuse normal saline as stated in option C.

A. A-negative (A-), B-negative (B-), AB-positive (AB+), and O-positive (O+). B. A-positive (A+), AB-negative (AB-), O-positive (O+), and B-negative (B-). C. AB-negative (AB-), O-positive (O+), AB-positive (AB+), and B-positive (B+). D. O-negative (O-), B-positive (B+), and O-positive (O+). E. None F. None

Correct Answer is D

Explanation

A. A-negative (A-) and AB-positive (AB+) are incompatible with B-positive (B+), as individuals with B+ blood can only receive blood from B or O types.
B. A-positive (A+) and AB-negative (AB-) are incompatible for the same reason.
C. AB-negative (AB-) and AB-positive (AB+) are not suitable donors for B-positive (B+) recipients.
D. O-negative (O-), B-positive (B+), and O-positive (O+) are all compatible with B-positive (B+), making this the correct choice.
