Answer to Question 1

ANS: B
Total cycle time = 60 s  frequency = 60  30 = 2 s. There are four equal parts to the total cycle time (add the I from the inspiratory time-to-expiratory time ratio to the E from the inspirato-ry time-to-expiratory time ratio, or 1 + 3 = 4). Inspiratory time = Total cycle time  (I + E) = 2  4 = 0.5 s.

Answer to Question 2

ANS: B
Inspiratory time = Tidal volume (in liters)  Flow rate (in liters/second) = 0.6 L  1 L/s = 0.6 s.

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.
