Answer to Question 1

ANS: C
One common method is to place water traps at low points in the circuit (both the inspiratory and expiratory limbs of ventilator circuits). The most common approach uses wire heating elements inserted into the ventilator circuit.

Answer to Question 2

ANS: A
To minimize this risk, place nebulizers in a superior position, so that any condensate travels downstream from the nebulizer.
