Answer to Question 1

ANS: B
During volume-controlled ventilation, the peak inspiratory pressure generated by the delivery of the volume varies according to the characteristics of the lungs. Worsening lung compliance is in-dicative of stiffening lungs. This would cause more pressure to be generated during the delivery of a set volume.

Answer to Question 2

ANS: B
The sine-like flow waveform begins at zero and reaches the maximum inspiratory flow in the middle of inspiration. It then tapers down to zero.

The human body's pharmacokinetics are quite varied. Our hair holds onto drugs longer than our urine, blood, or saliva. For example, alcohol can be detected in the hair for up to 90 days after it was consumed. The same is true for marijuana, cocaine, ecstasy, heroin, methamphetamine, and nicotine.
