Answer #1

Ans

A) Cancer chemotherapy drug administration.

Most patients are given antinausea medication, called an antiemetic, before chemotherapy is administered. Antiemetics are used to block the nerve impulse that travels from the blood or stomach to the brain (where the vomiting center is located).

Metoclopramide. Metoclopramide has proved to be generally safe and effective when given in high intravenous doses prior to chemotherapy. Metoclopramide was thought to function as an antiemetic through blockade of dopamine receptors
