It


-26. Bronchial intubation of the right or left mainstem bronchus can easily occur during infant endotracheal intubation because
a. the trachea is relatively short. '

b. the distance from the lips to the larynx is relatively short.

c. the use of tubes without cuffs allows the tube to slip distally.

d. the mainstem bronchi are less angulated iin their relation to the trachea.

She is nasotracheally intubated and is being mechanically ventilated. Her carboxyhemoglobin level is 10%. Her arterial blood gas analyses reveal PaO2 of 40 mm Hg, PaCO2 of 60 mm Hg, and pH of 7.25. Appropriate immediate management at this time is to


a. ensure adequate tissue perfusion.

d reassess for the presence of a pneumothorax.

e administer intravenous narcotics in small amounts.
