A client has a history of severe allergic reactions and is scheduled to receive a blood transfusion. What intervention should the nurse implement to prevent an allergic transfusion reaction in this client?
Pre-medicate the client with antihistamines before the transfusion.
Administer the blood transfusion rapidly to minimize exposure.
Ensure that the blood product is warmed before administration.
Monitor the client's vital signs frequently during the transfusion.
The Correct Answer is A
A) Correct: Pre-medicating the client with antihistamines before the transfusion can help prevent or minimize allergic transfusion reactions in clients with a history of severe allergies. Antihistamines block histamine release, reducing the risk of allergic symptoms.
B) Incorrect: Administering the blood transfusion rapidly is not a preventive measure for allergic transfusion reactions. In fact, rapid administration may increase the risk of adverse reactions.
C) Incorrect: Warming the blood product before administration is important to prevent hypothermia but is not directly related to preventing allergic transfusion reactions.
D) Incorrect: Monitoring the client's vital signs during the transfusion is a standard practice, but it is not the primary intervention for preventing allergic transfusion reactions. Pre-medication with antihistamines is a more targeted approach.

Correct Answer is B
Explanation
A) Incorrect: Administering a bolus of normal saline may help increase intravascular volume, but it is not the first intervention to be implemented. The nurse should first identify the cause of the client's symptoms and take appropriate actions.
B) Correct: The client's symptoms of feeling lightheaded and dizzy, along with a drop in blood pressure and an increase in heart rate, suggest orthostatic hypotension. The nurse's first intervention should be to elevate the client's feet and lower the head to improve blood flow to the brain.
C) Incorrect: Checking the client's hemoglobin and hematocrit levels is essential but may not be the first intervention in this situation. The client's symptoms indicate an immediate need to address the orthostatic hypotension.
D) Incorrect: Notifying the healthcare provider for further evaluation is important, but it may not be the first intervention. The nurse should first take immediate actions to address the client's symptoms of orthostatic hypotension.
Questions
Correct Answer is A
Explanation
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.
