A nurse is preparing to crossmatch blood for a client who requires a blood transfusion. Which blood component is involved in the crossmatching process?
Red blood cells.
White blood cells.
Platelets.
Plasma.
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.
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.

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.
Correct Answer is C
Explanation
A) Incorrect: Warming the blood product in a microwave oven is not an appropriate action and could lead to hemolysis of the blood components. Blood should be warmed using an approved blood warmer designed for this purpose.
B) Incorrect: Administering a discolored blood product or one containing clots is unsafe and could cause harm to the client. The nurse should not proceed with the administration and should take appropriate actions.
C) Correct: If the nurse discovers that the blood product is discolored or contains clots, the nurse should discard the blood product appropriately and notify the blood bank immediately. This will ensure that the client receives a safe and suitable blood product for the transfusion.
D) Incorrect: Filtering the blood product through a standard IV filter is not sufficient to remove any clots present in the blood product. Using a blood product that appears abnormal could lead to adverse reactions in the client, so it is essential to obtain a replacement from the blood bank.
