Answer to Question 1

ANS: A, C
A chest tube or tubes may be inserted for continuous drainage of fluid, blood, or air from the pleural cavity and for medication instillation. To prevent the lung from collapsing, a closed drainage system is used, which maintains the lung cavity's normal negative pressure. The chest tubes are connected to a pleural drainage system with collection, water seal, and suction control chambers to drain secretions and reestablish negative pressure in the pleural space.

Answer to Question 2

ANS: B, C, D, E
Age-related changes that affect the respiratory system are dryer mucous membranes, which reduce ability to humidify inspired air, kyphosis, which restricts the expansion of the lung, stasis pooling of respiratory secretions, and reduced number of cilia, which make infection of the upper and lower airway more likely.
