Question

Quizplus · Accepted Answer

The description of a tube worn over the ears with application at the nose is consistent with a nasal cannula, which is commonly used to deliver oxygen therapy to patients with COPD. Endotracheal intubation involves insertion of a tube through the mouth or nose into the trachea, nasopharyngeal intubation involves insertion of a tube through the nose into the pharynx, and orotracheal intubation involves insertion of a tube through the mouth into the trachea. None of these options match the description given in the question.
