Answer to Question 1

ANS: D
As inspired gas moves into the lungs, it achieves BTPS conditions (body temperature, 37 C; barometric pressure; saturated with water vapor 100 relative humidity at 37 C). This point, normally approximately 5 cm below the carina, is called the isothermic saturation boundary.

Answer to Question 2

ANS: A
Currently, the American Heart Association recommends an initial energy level, if a biphasic de-fibrillator is available, of 120 to 200 J for defibrillation of adults and 2 to 4 J/kg for children and infants.

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.

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.
