Answer to Question 1

ANS: A
Antihistamines, alcohol, analgesics, benzodiazepines, barbiturates, antidepressants, muscle relaxants, and sedative hypnotics increase toxic effects. Fluid volume excess is not an adverse effect of cannabinoids. Previous use does not necessarily require increased dosage. There are no dietary restrictions with the use of cannabinoids.

Answer to Question 2

ANS: D
Anticipatory nausea and vomiting is a conditioned response triggered by the sight or smell of the clinic or hospital or by the knowledge that treatment is imminent. Delayed reaction from a previous treatment would have occurred in a shorter interval after the other treatment. Delayed emesis occurs 24 to 120 hours after the administration of chemotherapy. Although smells can trigger nausea, this is not likely the cause of this patient's sickness. Hyperemesis gravidarum is excessive vomiting and nausea associated with pregnancy.
