Final answer:
The priority nursing action is to administer epinephrine to a child who experienced an allergic reaction to a bee sting, as it can rapidly counteract severe allergic reactions. The Correct Answer is Option .A.
Step-by-step explanation:
The priority nursing action for a 7-year-old client who presents to the emergency room after experiencing an allergic reaction to a bee sting is to administer epinephrine to the client. Despite the current stable vital signs, bee stings can cause severe allergic reactions, and symptoms can worsen rapidly.
Epinephrine counteracts the severe drop in blood pressure that can result from an immune response and is used to treat systemic anaphylaxis by constricting blood vessels, raising blood pressure, and relaxing bronchial smooth muscle to improve breathing.
