Electrical injury arrest scene — DipIMC MCQ

Correct answer: C — Confirm power is isolated before approaching and starting resuscitation

Option C is correct because Scene safety comes first because rescuers must not become electrical casualties. Option A is less appropriate because oxygen may be supportive, but it does not address the defining time-critical problem first; option D is less appropriate because vascular access is useful, but it should not delay the immediate priority. Option B 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.
