Peri-arrest external haemorrhage — DipIMC MCQ

Correct answer: C — Control external haemorrhage immediately while coordinating rapid extrication

Option C is correct because Catastrophic haemorrhage control precedes other survey steps and should occur alongside rescue planning. Option E is less appropriate because oxygen may be supportive, but it does not address the defining time-critical problem first; option A 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 D 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.
