Answer to Question 1

ANS: D
When 2 puffs are needed, an interval of at least 1 minute should separate the first puff from the second. CFC propellants will be discontinued because of damage to the environment. The patient should begin inhaling and then activate the device. There is no need to store the drug in the refrigerator.

Answer to Question 2

ANS: B
Teriparatide is supplied in 3-mL injectors. The pen should be stored in the refrigerator and discarded after 28 days, even if some drug remains in the syringe. Although the drug is expensive, it is not correct to use what is in the syringe after 28 days. Drug may be left in the syringe even with correct dosing.
