Final answer:
To treat a febrile reaction during a blood transfusion, Acetaminophen should be administered to the patient. It is used to manage fever and provide comfort. For severe allergic reactions like anaphylactic shock, epinephrine is used instead.
Step-by-step explanation:
The student is asking about the appropriate medication to administer for a client who is exhibiting symptoms of a febrile reaction to a blood transfusion. In this scenario, the correct choice is A. Acetaminophen. Febrile reactions are a type of hypersensitivity reaction that can occur during a blood transfusion and are often characterized by fever. To manage the fever and provide comfort to the patient, acetaminophen is typically recommended as it is an antipyretic (fever-reducing) and analgesic (pain-relieving) medication.
For other types of reactions such as type III hypersensitivity reactions, anti-inflammatory steroid treatments are considered a common approach, specifically when there's tissue damage involved. However, for immediate, severe allergic reactions like anaphylactic shock, epinephrine is usually the drug of choice to counteract the life-threatening effects.
It is important to stop the blood transfusion immediately upon recognizing signs of a reaction, and to provide support and monitoring while administering the appropriate medication.
