Correct answer: D — Adrenaline 500 micrograms IM into the anterolateral thigh

She has anaphylaxis with airway, breathing and circulation features, so IM adrenaline is first-line. Antihistamines and steroids do not treat the life-threatening ABC problems. IV adrenaline is reserved for appropriately skilled clinicians in refractory shock with monitoring.
