Answer to Question 1

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.

Answer to Question 2

Answer: A
Range-of-motion exercises in the affected arm helps develop collateral drainage and prevent the development of lymphedema. The client should be instructed to protect the affected limb by not permitting blood pressure measurement and avoiding tight jewelry and clothing on the limb. There is no reason for the client to avoid cleansing the skin of the affected arm with soap. Consuming fresh fruits and vegetables will not prevent the development of lymphedema.
