Correct answer: A — Intramuscular epinephrine into the mid-anterolateral thigh
Anaphylaxis with airway and cardiovascular features requires immediate intramuscular epinephrine. Antihistamines, bronchodilators and corticosteroids are adjuncts and must not delay epinephrine. Tryptase is not needed to make the acute diagnosis in a classic exposure-related presentation.
