A client prescribed tamoxifen (Nolvadex) for breast cancer treatment asks the nurse how the medication works. What is the best response by the nurse?
A) "Tamoxifen works by inhibiting the cellular mitosis of breast cancer."
B) "Tamoxifen works by blocking estrogen receptors on breast tissue."
C) "Tamoxifen works by binding to the DNA of breast cancer cells."
D) "Tamoxifen works by inhibiting the metabolism of breast cancer cells."
Answer: B
Breast cancer is dependent on estrogen for growth. Tamoxifen (Nolvadex) acts by blocking estrogen receptors; the tumor is deprived of estrogen. Tamoxifen does not inhibit the metabolism of breast cancer cells. Tamoxifen does not inhibit the cellular mitosis of breast cancer. Tamoxifen does not bind to the DNA of breast cancer cells.
