Answer :
The nurse first action should be subcutaneous epinephrine administration
Why epiphrine is administered?
When employing the airway, breathing, and circulation approach to client care, the nurse's top priority should be to provide epinephrine. Epinephrine causes bronchodilation of the lungs and an increase in blood pressure by acting on adrenergic receptors.
It more effectively treats anaphylaxis than any other therapy because it stimulates both alpha and beta adrenergic receptors to produce these effects.
Epinephrine injections are used to treat life-threatening allergic reactions brought on by foods, medications, latex, insect bites or stings, and other causes, in addition to emergency medical care.
