Answer to Question 1

ANS: D
The flow setting on a mechanical ventilator determines how fast the inspired gas will be deliv-ered to the patient. During continuous mandatory ventilation (CMV), high flows shorten inspira-tory time (TI) and may result in higher peak pressures and poor gas distribution.

Answer to Question 2

ANS: D
In situations where plateau pressure (PPlateau) is critical, changing to a descending ramp in order to reduce peak pressures may increase the mean airway pressure.

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
