Answer to Question 1

Ans:
B

Feedback:

Hormone therapy is used to block the effects of estrogen on the growth of breast cancer cells. Tamoxifen is a nonsteroidal antiestrogen that binds to estrogen receptors and blocks the effects of estrogens on the growth of malignant cells in the breast. Herceptin is used to stop the growth of breast tumors that express the HER2/neu receptor on their cell surface. Arimidex, an aromatase inhibitor, blocks the enzyme that converts androstenedione and testosterone to estrogen in the peripheral tissues. This reduces the circulating estrogen levels in postmenopausal women.

Answer to Question 2

Ans:
A, B, C, E

Feedback:

Cryptorchidism, luteal phase defects, low pituitary hormone levels, and an inability of the tubes to pick up an ovum can all contribute to infertility. A large amount of clear, stretchy cervical mucus is a normal finding. Cervical cultures for gonorrhea, chlamydial infection, and mycoplasmal infection should be obtained and treatment instituted as needed.
