Correct answer: D — Intramuscular adrenaline into the anterolateral thigh

This is anaphylaxis with respiratory and cardiovascular involvement, and IM adrenaline into the anterolateral thigh is first-line. Antihistamines and steroids do not treat airway oedema or shock and should not delay adrenaline. The pearl is that vomiting plus wheeze or hypotension after allergen exposure is anaphylaxis, not a simple rash reaction.
