Correct answer: A — Give IM adrenaline 500 micrograms and repeat after 5 minutes

The best answer is “Give IM adrenaline 500 micrograms and repeat after 5 minutes”. Airway compromise and shock after allergen exposure require IM adrenaline 500 micrograms in the anterolateral thigh, with airway management, oxygen, IV access and fluid resuscitation as indicated. Repeat IM adrenaline after five minutes if compromise persists. Antihistamines and corticosteroids are not first-line emergency treatment, and IV 1 mg adrenaline is dangerous outside expert monitored use.
