Question

in addition to clinical assessment, which is the most reliable method to confirm and monitor correct placement of an endotracheal tube? choose the correct answer arterial blood gases hemoglobin levels chest radiography continuous waveform capnography

Explanation:

Continuous waveform capnography is highly reliable for confirming and monitoring endotracheal tube placement as it directly measures the presence of exhaled carbon - dioxide, indicating proper tracheal placement. Arterial blood gases measure blood gas levels, hemoglobin levels measure the oxygen - carrying capacity of blood, and chest radiography can confirm placement but is not as real - time or sensitive as capnography for immediate confirmation and continuous monitoring.

Answer:

Continuous waveform capnography
