Answer to Question 1

ANS: B
During the application of hot therapies (thermal ablation) like laser, electrosurgery, or argon plasma coagulation, the FiO2 should always be maintained below 40 to prevent endobronchial ignition.

Answer to Question 2

ANS: B
There are two major complications of TBBx, pneumothorax and bleeding. Adequate sedation and cough suppression are important to reduce the risk of pneumothorax arising from cough-induced barotrauma.
