Correct answer: B — Give intramuscular adrenaline 500 micrograms into the anterolateral thigh

Give intramuscular adrenaline 500 micrograms into the anterolateral thigh is the best answer because adult anaphylaxis with airway, breathing or circulation compromise is treated first-line with IM adrenaline 500 micrograms. Give intravenous adrenaline 1 mg as a rapid bolus is less appropriate because IV bolus adrenaline is reserved for cardiac arrest or expert titrated use; Give nebulised salbutamol as sole treatment is less appropriate because bronchodilator therapy may help wheeze but does not treat systemic shock. Give intramuscular adrenaline 1 mg and Delay medication until hospital review are also suboptimal because they move attention away from the key pre-hospital priority.. The key DipIMC principle is to treat immediate reversible threats, communicate clearly and move the patient toward the right definitive care.
