Answer to Question 1

ANS: C
MAOIs act by blocking the metabolic destruction of epinephrine, norepinephrine, dopamine, and serotonin neurotransmitters by the enzyme monoamine oxidase in the presynaptic neurons of the brain. They prevent the degradation of these central nervous system (CNS) neurotransmitters so that their concentration is increased. MAOIs do not block or increase the reuptake of neurotransmitters. MAOIs do not increase production of neurotransmitters.

Answer to Question 2

ANS: B
The physiological manifestations of depression (sleep disturbance, change in appetite, loss of energy, fatigue, palpitations) begin to be alleviated within the first week of therapy. It takes longer than 3 days for the symptoms to improve. Four weeks and 2 months are longer than it takes for the symptoms to improve.
