Epinephrine is indicated for patients with an allergic reaction when:

• A. Only when there is urticaria
• B. Only when there is a mild rash
• C. Itching without airway symptoms
• D. Wheezing and hypotension are present

Answer: (D)

Epinephrine is the first-line treatment for anaphylaxis because it tackles both airway swelling and low blood pressure. It tightens blood vessels to raise blood pressure and reduce swelling, while also relaxing bronchial smooth muscle to relieve wheezing. When a patient has wheezing and hypotension, these signs show simultaneous airway involvement and circulatory compromise—classic features of anaphylaxis that require epinephrine. Isolated itching, a mild rash, or itching without airway symptoms don’t on their own indicate anaphylaxis that would mandate epinephrine, though they still require careful assessment and appropriate treatment per protocol.
