Answer to Question 1

ANS: D
Anticholinergic agents are used to treat motion sickness by counterbalancing the excessive amounts of acetylcholine present. Serotonin antagonists are used in the treatment of emesis associated with cancer chemotherapy, radiation therapy, and postoperative nausea and vomiting. Phenothiazines are used in the treatment of mild to moderate nausea and vomiting associated with anesthesia and surgery, radiation therapy, and cancer chemotherapy. Corticosteroids are used in the treatment of nausea and vomiting related to pregnancy, postsurgical state, chemotherapy, radiation, and bowel obstruction.

Answer to Question 2

ANS: C
Metoclopramide (Reglan) is an antiemetic and antagonist of dopamine and serotonin receptors. In addition to acting on receptor sites in the brain, metoclopramide increases sphincter tone in the gastrointestinal tract, which reduces nausea and vomiting. Metoclopramide does not affect anesthesia or the vascular system and does not have analgesic effects.
