Very hard

A patient has just been intubated during emergency care. Which finding provides the most reliable immediate evidence that the tube is in the trachea?

Correct answer: C. Continuous waveform capnography showing exhaled carbon dioxide

  • A. Equal chest movement on both sides
  • B. Auscultated breath sounds over both lungs
  • C. Continuous waveform capnography showing exhaled carbon dioxide
  • D. A pulse oximeter reading of 96 percent

Explanation

Continuous waveform capnography confirms exhaled carbon dioxide and is the most reliable immediate method for confirming tracheal placement. Chest movement and oxygen saturation can remain present briefly even when the tube is misplaced.
