Answer to Question 1

ANS: C
When administering aerosolized pentamidine, isolation, an environmental containment system (e.g., a booth or negative pressure room), and personnel barrier protection should be provided. Subjects should be screened for tuberculosis. The drug is given using a nebulizer system with one-way valves and scavenging expiratory filters (e.g., the Respirgard). This reduces environ-mental contamination. Nebulizer systems capable of producing an MMAD of 1 to 2 m for pe-ripheral lung deposition may reduce coughing.

Answer to Question 2

ANS: B
Zileuton inhibits the 5-lipoxygenase enzyme that catalyzes the formation of leukotrienes from arachidonic acid, as also shown in Figure 35-8.
