What is the recommended action for a nurse when a patient exhibits signs of anaphylaxis?

When a patient exhibits signs of anaphylaxis, the recommended action is to prepare to administer epinephrine immediately. Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur rapidly and requires prompt treatment to prevent further complications. Epinephrine is the first-line medication for treating anaphylaxis because it acts quickly to constrict blood vessels, increase heart rate, and open the airways, thereby reversing many of the life-threatening symptoms associated with this condition.

Timely administration of epinephrine can be critical in managing anaphylaxis and can significantly reduce the risk of severe outcomes, including respiratory failure or shock. This response highlights the urgency of the situation; while antihistamines and monitoring are important in allergic reactions, they do not provide the immediate action needed for anaphylaxis. Cold compresses would not address the systemic nature of anaphylaxis, and documentation, while crucial in the overall nursing process, does not provide any immediate relief or intervention for the patient experiencing such an acute clinical emergency.
