      Thrombus formation in the vein.

    • B. 

      Pain and discomfort.

    • C. 

      Infection.

    • D. 

      Occlusion of the catheter as the result of an intra-lumen clot.

  • 2. 
    Nurse Blessy is doing some patient education related to a patient’s central venous access device. Which of the following statements will the nurse make to the patient?
    • A. 

      “These type of devices are essentially risk free.”

    • B. 

      “These devices seldom work for more than a week or two necessitating replacement.”

    • C. 

      “The dressing should only the changed by your doctor.”

    • D. 

      “Heparin in instilled into the lumen of the catheter to decrease the risk of clotting.”

  • 3.

    • A. 

      Cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA.

    • 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).

  • 7. 
    Estrogen antagonists are used to treat estrogen hormone-dependent cancer. such as breast carcinomA. Androgen antagonists block testosterone stimulation of androgen-dependent cancers. An example of an androgen-dependent cancer would be:
    • A. 

      Prostate cancer.

    • 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. 

      Ondansetron (Zofran).

    • B. 

      Fluoxetine (Prozac).

    • C. 

      Paroxetine (Paxil).

    • D. 

      Sertraline (Zoloft).

  • 9. 
    Methotrexate. the most widely used antimetabolite in cancer chemotherapy does not penetrate the central nervous system (CNS). To treat CNS disease this drug must be administered:
    • 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. 

      Pulse therapy.

    • D.
