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.
