Answer to Question 1

ANS: C
As shown in Figure 43-1, there are four distinct phases to a normal cough: irritation, inspiration, compression, and expulsion.

Answer to Question 2

ANS: D
Infection is a good example of cough stimulation due to an inflammatory process. Foreign bodies can provoke a cough through mechanical stimulation. Chemical stimulation can occur when irri-tating gases are inhaled (e.g., cigarette smoke). Finally, cold air may cause thermal stimulation of sensory nerves and produce a cough.
