Answer to Question 1

D
Patients with unilateral lung disease should be positioned with the healthy lung in a dependent position. Because gravity normally facilitates preferential ventilation and perfusion to the dependent areas of the lungs, the best gas exchange would take place in the dependent areas of the lungs. Thus, the goal of positioning is to place the least affected area of the patient's lung in the most dependent position. Patients with unilateral lung disease should be positioned with the healthy lung in a dependent position.

Answer to Question 2

C
The mean arterial pressure is one-third systole and two-thirds diastole.
