Answer to Question 1

ANS: C
Taylor dispersion is the enhanced mixing of gases associated with the turbulent flow of high-velocity gases moving through small airways and their bifurcations. Taylor dispersion occurs when two gas streams meet, creating an erratic pattern of eddies and streams.

Answer to Question 2

ANS: D
The tidal volume of a breath during high-frequency jet ventilation depends on four basic factors: (1) the length of the pulsation, (2) the amplitude or driving pressure of the jet, (3) the jet orifice size, and (4) the patient's lung characteristics.
