Answer to Question 1

ANS: B
Removal of the inner cannula opens the fenestration allowing air to pass into the upper airway. Capping or placing a peaking valve on the proximal opening of the tube's outer cannula, accom-panied by deflation of the cuff, allows for assessment of upper airway function.

Answer to Question 2

ANS: C
One problem associated with this type of tracheostomy tube is malposition of the fenestration, such as between the skin and stoma, or against the posterior wall of the larynx.
