Answer to Question 1

ANS: C
Phentolamine has actions on both alpha1 and alpha2 receptors; it is not selective for alpha1 receptors only. It blocks both epinephrine- and norepinephrine-mediated vasoconstriction. It is used to treat pheochromocytoma. Side effects include tachycardia and hypotension.

Answer to Question 2

ANS: B
Blockade of beta1 receptors in the heart reduces cardiac work by reducing the heart rate, the force of contraction, and the velocity of impulse conduction through the AV node. Beta blockers result in bronchoconstriction, not bronchodilation. They do not increase blood flow to the heart. Cardiac output is decreased, not increased.
