A client is scheduled to receive a blood transfusion, but the nurse discovers that the blood product appears discolored or contains clots. What should the nurse do next?

A) Incorrect: Elevating the head of the bed may help promote lung expansion, but it is not the nurse's priority action when the client is experiencing severe symptoms like dyspnea, tachycardia, and chest pain during a transfusion.

B) Incorrect: Administering diuretics is not the appropriate action for the client's symptoms, which suggest a possible transfusion-related acute lung injury (TRALI) or acute hemolytic transfusion reaction. Diuretics will not address the underlying cause.

C) Correct: The client's symptoms of dyspnea, tachycardia, and chest pain indicate a potential severe transfusion reaction. The nurse's priority action is to stop the transfusion immediately and notify the healthcare provider for further evaluation and intervention.

D) Incorrect: Continuing the transfusion at a slower rate is not appropriate when the client is experiencing severe symptoms. The nurse should first stop the transfusion and then notify the healthcare provider.

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.
