Answer to Question 1

ANS: D
Pretreatment with an adrenergic bronchodilator, allowing adequate time for a bronchodilatory effect to be produced, can prevent or reduce airway resistance with acetylcysteine.

Answer to Question 2

ANS: D
Acetylcysteine acts as a classic mucolytic to reduce the viscosity of mucus by substituting its own sulfhydryl group for the disulfide group in mucus, thereby breaking a portion of the bond forming the gel structure.
