Answer to Question 1

ANS: B
Leukotrienes are a class of anti-inflammatory agents that block leukotriene formation, and they are part of the inflammatory pathway that causes bronchoconstriction . Leukotrienes work to reduce bronchoconstriction, and they do not inhibit histamine release or affect viscosity of secretions.

Answer to Question 2

ANS: D
Anticholinergic bronchodilating agents cause mydriasis (dilation of the pupils) and cycloplegia (loss of power in the ciliary muscle); therefore, they should not be used in patients with a history of closed-angle glaucoma. Diabetes, hypertension, and liver disease are not affected by the use of anticholinergic bronchodilating agents.
