Answer to Question 1

ANS: C, D
The CTZ stimulates the VC to induce vomiting as well as samples blood and spinal fluid for potentially toxic substances. The CTZ does not initiate vomiting or coordinate the vomiting reflex.

Answer to Question 2

ANS: D
Ginger is an herb used in many cultures to treat pregnancy-induced nausea and vomiting. Mint is often used to treat mild dyspepsia. Hyssop is used as an expectorant and anticatarrhal. Echinacea is used to boost the immune system.
