Answer to Question 1

ANS: A
If there are no secretions, an HME would be suitable. Use the algorithm for selecting the cor-rect humidity and bland aerosol therapy located in the text.

Answer to Question 2

ANS: C
The most accurate and reliable way to ensure that patients are receiving gas at the expected tem-perature and humidity level is to measure these parameters with the portable battery-operated digital hygrometer-thermometer system. Humidity control on a hot-wire humidification system will not provide a measurement of absolute humidity or relative humidity; instead, it will enable the measurement of only the temperature differential between the humidifier and the airway sensor.
