Answer to Question 1

ANS: B
A. Incorrect response: The peak inspiratory pressure will increase in the presence of auto-PEEP during volume-targeted ventilation.
B. Correct response: The tidal volume will be reduced in the presence of auto-PEEP during pressure-targeted ventilation.
C. Incorrect response: Auto-PEEP will not affect the flow-termination criterion.
D. Incorrect response: The inspiratory time is not affected by auto-PEEP.

Answer to Question 2

A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: In a normal person, gravitational effects on lung water and required stretch make airway resistance slightly higher in the bases than in other regions of the lungs.
D. Incorrect response: See explanation C.

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
