Step-by-step explanation:
Epinephrine would be given to a newborn in the event of anaphylaxis, which is a severe allergic reaction that can be life-threatening. Anaphylaxis can occur when a newborn is exposed to an allergen through eating, injection, or inhalation. Epinephrine is used to counteract the drop in blood pressure and relax bronchial smooth muscle that can occur during anaphylaxis. It is often administered through an auto-injector, such as an EpiPen®, and can be lifesaving in these situations.
