Answer to Question 1

ANS: D
Endotracheal tubes allow ventilation with high levels of positive pressure; provide direct access to the lower airway for secretion removal and drug delivery; prevent aspiration of foreign materi-al into the lung; and permit bronchoscopic examination of the peripheral airways. None of the other airways mentioned are able to maintain ventilation with high pressures without leaking or allowing gastric distention.

Answer to Question 2

ANS: B
The endotracheal tube tip can be controlled with an Endotrol tube. With this device, an implant-ed string with a pull-ring turns the tip anterior when pulled (Figure 5-35). This device is particu-larly well-suited for blind nasotracheal intubation.
