Answer to Question 1

ANS: B
Antidepressant drugs appear to work by blocking presynaptic reuptake of serotonin and norepi-nephrine.

Answer to Question 2

ANS: A
Orthostatic hypotension is the most serious of the common adverse effects of tricyclic antide-pressant drug therapy and is due, in part, to blockade of alpha-1 receptors on blood vessels.
