Answer to Question 1

ANS: C
Higher flow (up to 100 L/min) may improve gas exchange in COPD patients, probably because of the resulting increase in expiratory time.

Answer to Question 2

ANS: A
To decrease inspiratory time, one may increase the peak flow, decrease the tidal volume, or change from a down ramp or sine wave to a square wave flow pattern.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
