Answer to Question 1

ANS: B
Antiestrogen drugs cause proliferation of endometrial tissue by acting as receptor agonists at receptors in the uterus. Antiestrogen drugs increase the risk of thromboembolic events. Aromatase inhibitors block the production of estrogen from androgenic precursors, not by the ovaries. Aromatase inhibitors are used to treat ER-positive breast cancer.

Answer to Question 2

ANS: C
If the neutrophil count drops below 1500/mm3, the nurse should withhold the dose and notify the prescriber. The other values do not indicate a need to withhold the dose.
