Answer to Question 1

ANS: C
Tamoxifen (Nolvadex) reduces the estrogen available to breast tumors to stop or prevent growth. This drug does not block the release of luteinizing hormone to prevent the ovaries from producing estrogen; leuprolide (Lupron) does this. Chemotherapy agents such as ixabepilone (Ixempra) interfere with cancer cell division, and doxorubicin (Adriamycin) inhibits DNA synthesis in susceptible cells.

Answer to Question 2

ANS: D
A dusky color of the breast flap could indicate poor tissue perfusion and a decreased capillary refill. The nurse should notify the surgeon to preserve the tissue. It is normal to have a slightly reddened incision as the skin heals. The blood pressure is within normal limits and the temperature is slightly elevated but should be monitored.
