Answer to Question 1

ANS: A
High-frequency jet ventilation operates by passing gas from a high-pressure source through a var-iable regulator that reduces the pressure to the desired working level. The gas passes through a device, usually a solenoid or a fluidic valve, which governs the amount and duration of flow. The gas jet is delivered through a specially made triple-lumen endotracheal tube, which is similar to conventional endotracheal tubes except that two additional small lines are added. One line is for delivering jet ventilation, and the other is for monitoring distal airway pressures.

Answer to Question 2

ANS: B
The pressure-time waveform is raised from the zero line; this means that there is positive end-expiratory pressure. The flat pressure wave is indicative of pressure-limited breaths. The higher level represents the ventilator pressure-limited breath, and the lower level waveform rep-resents the pressure-supported breaths.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
