Answer to Question 1

ANS: C
The scalar shows a pressure overshoot owing to the rapid flow rate at the very beginning of in-spiration. Adjusting the slope of the pressure and flow curves can change the rate of gas delivery at the very beginning of inspiration. This tapers the curves slightly until they reach their maximum value. Decreasing the pressure setting may alleviate the overshooting problem, but it does not provide the same level of assistance to the patient. Inspiratory time and volume are controlled by the patient in pressure-support ventilation and cannot be adjusted.

Answer to Question 2

ANS: C
During pressure-controlled ventilation, the delivery of the volume varies according to the charac-teristics of the lungs. Improving compliance makes it easier to deliver a volume with the same set pressure.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

The use of salicylates dates back 2,500 years to Hippocrates’s recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.
