Correct answer: E — Activate major trauma haemorrhage protocol with balanced blood-product resuscitation

Activate major trauma haemorrhage protocol with balanced blood-product resuscitation is the single best answer because the age, timing, examination findings and investigations in the vignette fit Major haemorrhage better than the alternatives. The most tempting distractor is less appropriate because it either treats a neighbouring presentation, delays a time-critical intervention, or ignores a key discriminator in the stem. The remaining options are suboptimal because they would miss the diagnosis, use an investigation or treatment in the wrong sequence, or fail to address safety and follow-up. Canadian practice should be anchored to ATLS Canada guidance, with attention to acuity, safety-netting and local provincial pathways.
