Answer to Question 1

B
A flail chest is defined as double fractures of three or more adjacent ribs.

Answer to Question 2

A
Clinical manifestations associated with the more negative intrapleural pressures needed during inspiration include, but are not limited to, seesaw breathing movement and cyanosis of the dependent thoracic areas. Chest assessment findings may include rhonchi and crackles for breath sounds because of meconium in the airways. If the neonate is hypoxic, he or she may display expiratory grunting. However, these last two findings are not directly associated with the more negative intrapleural pressures needed during inspiration.
