Paediatric shockable arrest drug — DipIMC MCQ

Correct answer: B — Adrenaline 10 micrograms/kg IV or IO after the third shock

Option B is correct because Paediatric ALS uses weight-based adrenaline after the third shock for shockable rhythms. Option D is less appropriate because that dose is an ALS cardiac-arrest dose and is unsafe for this non-arrest indication; option A is less appropriate because aspirin is useful in ACS but inappropriate for this presentation. Option E is less appropriate because untitrated opioid dosing can cause avoidable hypotension or respiratory depression; option C is less appropriate because steroids have delayed onset and should not replace the immediate treatment. Clinical pearl: in DipIMC-style questions, the best answer is the intervention that changes outcome earliest in the pre-hospital phase.
