Answer to Question 1

D
Feedback:
TCAs inhibit presynaptic reuptake of norepinephrine and serotonin, which cause an accumulation of the neurotransmitters that is thought to create the antidepressant effect. Monoamine oxidase inhibitors irreversibly inhibit monoamine oxidase that breaks down norepinephrine and serotonin. Selective serotonin reuptake inhibitors block the reuptake of serotonin; gamma-aminobutyric acid inhibits nerve activity.

Answer to Question 2

D
Feedback:
Clean dry socks should be applied when treating athlete's foot to help eradicate the infection because they will keep the feet dry as well as prevent the cream from being wiped away. A kling dressing is not necessary as it would bind the feet and interfere with mobility and increase the risk of systemic absorption. Medication should not be removed once applied, and there is no need to elevate the feet unless another medical condition warrants this action.
