Answer to Question 1

ANS: B
Sudden cardiac arrest (SCA) is the leading cause of death in many parts of the world.

Answer to Question 2

ANS: B
If desaturation occurs, the FiO2 should be increased with an oxygen therapy device. Alternative-ly, the procedure can be temporarily halted, and oxygen can be given through the scope's open channel. The latter technique has the advantage of defogging the scope and diffusing any secre-tions. Suctioning for brief periods will help reduce the incidence or severity of hypoxemia.
