  a. Inhibiting luteinizing hormone (LH), blocking release of ovum from a follicle
  b. Thinning cervical mucus, which inhibits sperm migration
  c. Trapping the ovum in the endometrial wall, preventing its growth
  d. Blocking follicle-stimulating hormone (FSH), thereby preventing release of ovum

Question 2

The nurse is instructing a patient on use of a transdermal contraceptive. When evaluating the patient's understanding of the information provided, the nurse identifies a need for further education when the patient states

Answer to Question 1

ANS: D
Estrogens block pituitary release of FSH, preventing the ovaries from developing a follicle from which the ovum is released. Progestins inhibit pituitary release of LH, the hormone responsible for releasing an ovum from a follicle. Estrogens and progestins alter cervical mucus by making it thick and viscous, inhibiting sperm migration. Hormones also change the endometrial wall, impairing implantation of the fertilized ovum.

Answer to Question 2

ANS: D
Patches should not be cut. The first patch should be applied during the first 24 hours of the menstrual period. A backup contraceptive should be used concurrently for the first 7 days of the first cycle. When removing the patch, it should be folded over on itself and placed in a sturdy container.
