Answer to Question 1

ANS: B
Methylene blue dye in sterile saline is recommended for filling the endotracheal tube cuff. If the cuff is perforated, the dye acts as the indicator.

Answer to Question 2

ANS: C
In the Killian procedure, the frontal sinus cavity is reached by removing the floor or anterior wall of the sinus. This forms a large communication and drainage channel into the nose.
