Correct answer: D — Start ALS and give adrenaline according to cardiac arrest algorithm
Explanation lettering: B = shown as A · A = shown as B
D is correct: Once pulseless, anaphylaxis is treated as cardiac arrest with ALS adrenaline dosing rather than IM anaphylaxis dosing. A is less suitable because it moves the patient before the decisive threat or destination issue is addressed; B is less suitable because it moves the patient before the decisive threat or destination issue is addressed; C is less suitable because it does not address the discriminator in the vignette; E is less suitable because analgesia is important but does not replace the first physiological intervention. The most tempting alternative is therefore suboptimal because it either delays the time-critical pre-hospital intervention or sends the patient to the wrong level of care. The key DipIMC principle is focused cABCDE decision-making with early pre-alert, triage or retrieval escalation when the scene physiology demands it.
