Answer to Question 1

A
CINV caused by cisplatin is maximal 48 to 72 hours after dosing and can persist for 6 to 7 days, so an antiemetic such as aprepitant, which treats delayed emesis, is an important part of anti-emetic therapy. Antiemetics should be started 30 minutes before initiation of chemotherapy. Lo-razepam should be given to this patient, because the patient has had some experience with che-motherapy and is likely to have anticipatory emesis. There is no benefit to IV over oral dosing unless the patient has ongoing emesis.

Answer to Question 2

B
Abrupt discontinuation of selective serotonin reuptake inhibitors (SSRIs) can cause a withdrawal syndrome, so these drugs should be withdrawn gradually. After symptoms are in remission, treatment should continue for 4 to 9 months to prevent relapse; these drugs are not taken indefi-nitely. It is incorrect to counsel the patient to stop taking the drug without tapering it. Drug holi-days are used to minimize sexual dysfunction side effects, not to monitor symptoms.
