Answer to Question 1

B
Feedback:
Ephedrine is a mixed-acting adrenergic drug that acts by stimulating alpha1 and beta receptors and causing release of norepinephrine from presynaptic terminals. It is used in the treatment of bronchial asthma. Epinephrine is not a mixed-acting adrenergic drug. Pseudoephedrine is a related drug, stimulating alpha1 and beta receptors. It is used as a nasal decongestant. Isoproterenol is a synthetic catecholamine that acts on beta1- and beta2-adrenergic receptors.

Answer to Question 2

C
Feedback:
An intra-articular injection of corticosteroid provides decreased pain and improved movement in 2 to 8 weeks.
