Adult VF cardiac arrest — DipIMC MCQ

Correct answer: D — Deliver the shock and resume chest compressions immediately

Option D is correct because Shockable cardiac arrest requires prompt defibrillation with immediate resumption of CPR to minimise pauses. Option C is less appropriate because oxygen may be supportive, but it does not address the defining time-critical problem first; option B is less appropriate because vascular access is useful, but it should not delay the immediate priority. Option A is less appropriate because it is plausible in a different scenario but suboptimal for the features described; option E is less appropriate because delay would increase clinical risk. Clinical pearl: in DipIMC-style questions, the best answer is the intervention that changes outcome earliest in the pre-hospital phase.
