Answer to Question 1

ANS: A
The most sensitive and rapid way to confirm correct placement is to detect expired carbon diox-ide by means of a capnograph or a color-change capnometric device. A chest radiograph is used to determine proper position with respect to the carina. Chest auscultation is subjective, and re-ferred sounds from the stomach might be confused with breath sounds. Fiberoptic bronchoscopy is another way to confirm placement, but this procedure may take time for preparation.

Answer to Question 2

ANS: D
A curved blade enables identification of the epiglottis; the blade tip should be inserted above the epiglottis into the vallecula, which is the space between the tongue base and the epiglottis. With a forward and upward lift, the larynx is illuminated and the endotracheal tube can be passed into the trachea. The blade is inserted along the right side of the tongue. The tip of the blade needs to be in the vallecula. The epiglottis should not be hooked with the tip of the blade.
