A. supine
B. left lateral decubitus
C. right lateral decubitus
D. prone
?ANS: B
A. Incorrect response: See explanation B.
B. Correct response: Perfusion and ventilation are normally preferentially distributed to the dependent portions of the lungs. For a patient with unilateral lung disease, clinicians tend to ventilate the patient with the "good lung down." This positioning amounts to a lateral decubitus position to improve oxygenation in both spontaneously breathing and mechanically ventilated patients. The patient in this problem has no right lung and would benefit from the left lateral decubitus position, which would make the remaining left lung dependent.
C. Incorrect response: See explanation B.
D. Incorrect response: See explanation B.
