Answer to Question 1

A
Feedback:
Drugs that deplete dopamine stores or block dopamine receptors, including the older antipsychotic drugs (phenothiazines and haloperidol), reserpine, and metoclopramide, can produce movement disorders such as secondary parkinsonism. Furosemide does not deplete dopamine stores. Psyllium does not deplete dopamine stores. Valproic acid does not deplete dopamine stores.

Answer to Question 2

C
Feedback:
Tretinoin is applied one time per day. Positive results from the medication will be noted in 12 weeks, not 1 week. The medication should not be applied two to three times per day. The medication should not be applied for 1 hour and then removed.
