Answer to Question 1

A
When distal airway and alveolar weakening is present, air trapping occurs, resulting in the depressed diaphragm on the chest radiograph and use of accessory muscles of inspiration.

Answer to Question 2

A
Because some patients have clinical manifestations associated with asthma but normal lung function, measurements of airway responsiveness to inhaled methacholine or a cold air challenge may be useful in confirming a diagnosis of asthma. A warm, humid air challenge would not be effective in producing results consistent with airway reactiveness. Body plethysmography is used to determine functional residual capacity. This would not be helpful in establishing a diagnosis of asthma.
