Answer to Question 1

B
Feedback:
Epinephrine may be injected subcutaneously in an acute attack of bronchoconstriction, with therapeutic effects in 5 minutes that last 4 hours. It is considered the drug of choice for the treatment of acute bronchospasm. Ipratropium bromide has an onset of action of 15 minutes when inhaled with a duration of 3 to 4 hours. Cromolyn is not for use during acute times of bronchospasm but is used to help prevent bronchospasm. Ephedrine can be used in acute bronchospasm but epinephrine remains the drug of choice.

Answer to Question 2

C
Feedback:
Triptans are a new class of selective serotonin receptor blockers that cause vasoconstriction; they are not associated with as many systemic adverse effects experienced in ergot therapy. Triptan therapy will enable her to live a near normal life even during headaches. Although adverse effects are fewer than those associated with ergot therapy, triptans can still cause dizziness, feelings of strangeness, and vertigo, so the patient should not drive while taking the drug. Medications are often only taken once due to prolonged half-lives, but some may be repeated in 2 to 4 hours if the headache does not subside.
