Initial management of an allergic reaction with signs of anaphylaxis should include...?

• A. Assess airway, breathing, and circulation and administer epinephrine if signs of anaphylaxis
• B. Administer antihistamines only
• C. Delay treatment until hydrocortisone is available
• D. Encourage patient to drink fluids

Answer: (A)

Managing suspected anaphylaxis starts with stabilizing the patient by focusing on airway, breathing, and circulation, and giving epinephrine immediately. Epinephrine is the first-line treatment because it rapidly reverses the dangerous effects of anaphylaxis: it reduces airway swelling and bronchospasm, improves blood pressure, and counteracts the vascular leak that leads to shock. This urgent action in the early minutes can be life-saving.

Adjuncts like antihistamines or steroids may help with symptoms, but they do not reverse airway compromise or shock quickly enough to treat the emergency. Antihistamines have a slower effect and don’t address breathing or airway edema, while steroids take hours to become effective and are not useful for the acute phase. Delaying treatment until hydrocortisone is available is dangerous. Encouraging the patient to drink fluids does not address the immediate airway and breathing issues and can delay critical care.

So, the essential initial step is to assess ABCs and administer epinephrine promptly when signs of anaphylaxis appear.
