Answer to Question 1

ANS: B
Chemotherapy is the mainstay of therapy for extensive local or disseminated neuroblastoma. The drugs of choice are vincristine, doxorubicin, cyclophosphamide, cisplatin, etoposide, ifosfamide, and carboplatin. These cause immunosuppression, so the laboratory values will indicate a low white blood cell count and hemoglobin.

Answer to Question 2

ANS: D
Sterile hemorrhagic cystitis is a side effect of chemical irritation to the bladder from chemotherapy or radiotherapy. It can be prevented by a liberal oral or parenteral fluid intake (at least one and a half times the recommended daily fluid requirement). The urine should be dilute so 1.005 is the expected specific gravity.
