Answer to Question 1

ANS: D
The appropriateness of the power setting is determined by observing chest wall movement, or the chest wiggle factor (CWF). Increased amplitude is also associated with increased chest wall movement. The CWF should be visible from the level of the clavicle to the midthigh. Assessment of chest wiggle is difficult in obese patients.

Answer to Question 2

ANS: B
The mPaw directly affects the PaO2 by changing the lung volume.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
