Answer to Question 1

D
Because of the instability of the flail area, the ribs and lung tissue will move in the opposite direction than normal during a breath. This can cause air to be shunted from one lung to the other during the ventilatory cycle.

Answer to Question 2

B
Due to the airway obstruction and retained secretions, the following chest assessment findings would be expected: decreased or increased tactile and vocal fremitus, hyperresonant percussion note, diminished breath sounds, diminished heart sounds, and bronchial breath sounds (over atelectasis). A hyperresonant percussion note would be expected with the hyperinflation of alveoli, not a dull percussion note.
