Answer to Question 1

ANS: D

Answer to Question 2

ANS: D
Humidifier heating systems also have a controller that regulates the element's electric power. In the simplest systems, the controller monitors the heating element, varying the delivered current to match either a preset or an adjustable temperature. In these systems, the patient's airway temper-ature has no effect on the controller.
