Correct answer: E — Remove everyone from exposure and give high-flow oxygen to symptomatic patients
Remove everyone from exposure and give high-flow oxygen to symptomatic patients is the best answer because carbon monoxide poisoning is treated by stopping exposure and giving high-concentration oxygen. Transport without treating the identified time-critical problem is less appropriate because movement alone may not reverse the immediate physiology; Perform a full secondary survey before treating the abnormality is less appropriate because secondary survey follows correction of immediate life threats. Give a large crystalloid bolus before controlling the injury and Wait for imaging before intervening are also suboptimal because they move attention away from the key pre-hospital priority.. The key DipIMC principle is to treat immediate reversible threats, communicate clearly and move the patient toward the right definitive care.
