- B.
Have few. if any. side effects.
- C.
Are used to treat multiple types of cancer.
- D.
Are cell cycle-specific agents.
- 4.Hormonal agents are used to treat some cancers. An example would be:
- A.
Thyroxine to treat thyroid cancer.
- B.
ACTH to treat adrenal carcinoma.
- C.
Estrogen antagonists to treat breast cancer.
- D.
Glucagon to treat pancreatic carcinoma.
- 5.Chemotherapeutic agents often produce a certain degree of myelosuppression including leukopeniA. Leukopenia does not present immediately but is delayed several days to weeks because:
- A.
The patient’s hemoglobin and hematocrit are normal.
- B.
Red blood cells are affected first.
- C.
Folic acid levels are normal.
- D.
The current white cell count is not affected by chemotherapy.
- 6.Currently. there is no way to prevent myelosuppression. However. there are medications available to elicit a more rapid bone marrow recovery. An example is:
- A.
Epoetin alfa (Epogen. Procrit).
- B.
Glucagon.
- C.
Fenofibrate (Tricor).
- D.
Lamotrigine (Lamictal).

- B.
Thyroid cancer.
- C.
Renal carcinoma.
- D.
Neuroblastoma.
- 8.Serotonin release stimulates vomiting following chemotherapy. Therefore. serotonin antagonists are effective in preventing and treating nausea and vomiting related to chemotherapy. An example of an effective serotonin antagonist antiemetic is:

- A.
Intravenously.
- B.
Subcutaneously.
- C.
Intrathecally.
- D.
By inhalation.
- 10.Methotrexate is a folate antagonist. It inhibits enzymes required for DNA base synthesis. To prevent harm to normal cells. a fully activated form of folic acid known as leucovorin (folinic acid; citrovorum factor) can be administered. Administration of leucovorin is known as:
- A.
Induction therapy.
- B.
Consolidation therapy.
- C.
