What is the appropriate nursing action for a patient with an allergic reaction?

Administering antihistamines and monitoring for airway compromise is the appropriate nursing action for a patient experiencing an allergic reaction. Antihistamines work by blocking the effects of histamine, a chemical released during an allergic response, which helps reduce symptoms such as itching, swelling, and hives. Additionally, monitoring for airway compromise is crucial because severe allergic reactions, known as anaphylaxis, can lead to swelling in the throat, difficulty breathing, and a rapid decline in the patient’s condition. Being vigilant in this aspect allows for timely intervention, potentially saving the patient's life if airway support is needed.

In contrast, giving pain medication immediately does not address the underlying cause of the allergic reaction. Discharging the patient is inappropriate during an active allergic response since appropriate treatment and monitoring are necessary before the patient can be safely discharged. Ignoring the symptoms would pose significant risks, as allergic reactions can escalate quickly, leading to severe complications. Therefore, the chosen action prioritizes the patient's safety and effectively addresses the allergic reaction.
