Sample item

What best confirms endotracheal tube placement?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Sustained capnography waveform

Persistent exhaled carbon dioxide on capnography is the most reliable routine confirmation of tracheal intubation because it demonstrates ongoing alveolar ventilation.

Option by option

  • A. Tube fogging only

    Tube fogging alone is unreliable for tube placement.

  • B. Sustained capnography waveform (correct)

    Correct: sustained capnography confirms ongoing tracheal ventilation.

  • C. Pulse palpation

    Pulse palpation gives no confirmation of tube location.

  • D. Chest movement alone

    Chest movement alone can be misleading.
