Answer to Question 1

ANS: C
Tricyclic antidepressants, similar to other classes of antidepressants, have initial responses that develop in approximately 1 to 3 weeks. Maximal responses may take up to 1 to 2 months to develop.
These time frames are incorrect.

Answer to Question 2

ANS: A
Fluoxetine produces selective inhibition of serotonin reuptake and intensifies transmission at serotonergic synapses.
Fluoxetine does not act by blocking uptake of monoamines or inhibiting monoamine oxidase-A nerve terminals, nor does it directly stimulate serotonin receptors.
