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.
