Correct answer: APerform emergency front-of-neck access, then confirm ventilation with capnography

Explanation lettering: C = shown as A · A = shown as C · E = shown as D · D = shown as E

C is correct in a cannot-intubate, cannot-oxygenate emergency. D and E use the remaining oxygen reserve without restoring ventilation. A and B are unsuitable while oxygenation has failed. This is a rescue oxygenation procedure rather than a diagnostic decision.
