Answer to Question 1

C
Feedback:
Orlistat decreases fat absorption, which leads to decreased caloric intake. Orlistat does not increase central nervous system stimulation. Orlistat does not inhibit reuptake of serotonin and norepinephrine. Orlistat does not decrease appetite because of the caffeine contained in the medication.

Answer to Question 2

B
Feedback:
Corticotropin-releasing hormone or factor (CRH or CRF) causes release of corticotropin (adrenocorticotropic hormone) in response to stress and threatening stimuli. Growth hormone releaseinhibiting hormone (somatostatin) inhibits release of growth hormone. Growth hormonereleasing hormone causes the release of growth hormone in response to low blood levels of GH. Thyrotropin-releasing hormone causes the release of TSH in response to stress, such as cold.
