Answer to Question 1

ANS: D
Because of tracheal mucosal blood pressure-flow characteristics, cuff pressure should be below 25 mm Hg to prevent tracheal ischemic damage. High cuff pressure is not an indication for extu-bation. Adding more volume would increase the cuff pressure even more, creating more of a blockage to blood and lymph circulation in the area surrounding the cuff.

Answer to Question 2

ANS: C
The curved blade gives better tongue control than the straight blade. Both types of blades must be inserted along the right side of the tongue. The Macintosh blade lifts the epiglottis indirectly by being placed in the vallecula, not directly on the epiglottis.
