What 2 hormones stimulate the release of the mature ovum from the ovary on day 12 of the
menstrual cycle? What 2 hormones will decrease if fertilization/implantation do not occur? -
correct answer ✔✔ LH and FSH
- Estrogen and progesterone -> menstruation
What secretes estrogen and progesterone and reaches its peak function about 8 days after
ovulation? - correct answer ✔✔ Corpus luteum (if fertilization occurs, this will last until placenta
develops/takes over this function)
When should prenatal care begin? - correct answer ✔✔ 12 weeks before gestation
What days are the highest chances of fertilization - correct answer ✔✔ Days 11-15
Treatments for BV, Candidiasis/yeast infection, and trichomoniasis - correct answer ✔✔ BV is
often treated with metronidazole (Flagyl). Candidiasis/yeast infection is common during
pregnancy and may be treated with fluconazole or with an OTC antifungal agent; Metronidazole
is the recommended treatment for trichomoniasis during pregnancy
Copper IUD - emergency contraceptive - correct answer ✔✔ A copper IUD can be placed within
5 days of unprotected sex to prevent pregnancy
- For greatest effectiveness, EC should be taken within 72 hours of the incident. EC works by
suppressing ovulation
, What is conception? - correct answer ✔✔ the union of a single egg (women are born w/ eggs
and are not released until puberty) with a single sperm
How long is the egg released from ovulation considered fertile? - correct answer ✔✔ 24 hrs
Where does fertilization occur? How long does it take a zygote to travel down the fallopian
tube? - correct answer ✔✔ in outer 1/3 of fallopian tube; 3-4 days
When does implantation occur? - correct answer ✔✔ 6-10 days after fertilization
What is the length of the embryonic stage? What forms in this stage? - correct answer ✔✔ Days
15- 8 weeks (weeks 8-40 - fetal developmental stage)
- MOST SUSCEPTIBLE TO TERATOGENS
- Amniotic sac and fluid forms - Purpose is to provide antibacterial properties and provide
cushion
- Yolk sac: transfers maternal nutrients and oxygen to the embryo; disappears after 5th/6th
week
- this is followed/accompanied by the development of the umbilical cord by day 14
When is circulation and transfer of nutrients/waste is in place from the umbilical cord - correct
answer ✔✔ Day 17 (structure is complete by 12 weeks)
What are the 3 placental functions? - correct answer ✔✔ 1) Endocrine function: Produces hCG,
which is detected in maternal serum by days 8-10 of conception, progesterone and estrogen (by
week 7)
2) Metabolic functions: respiration, nutrition, excretion, storage
3) Circulatory function: Depends on maternal BP
