The flashcards below were created by user jonas112 on FreezingBlue Flashcards. What would you like to do?


  1. What are the 3 major types of combined hormonal contraceptives (CHC)
    • OCP
    • patch
    • vaginal ring
  2. Describe how the CHC's work to prevent pregnancy
    • -The estrogen is the primary
    • reason that the brain thinks "hey we don't need to make FSH and
    • LH" - preventing ovulation

    • -The progesterone helps with
    • this, but its main effects are to thicken cervical mucus and thin the
    • endometrial wall
  3. When does most breakthrough follicle development happen? How can you prevent this?
    during the Hormone Free Interval (HFI), can prevent this by not giving women a hormone free interval (causing amenorrhea)
  4. What are the absolute contraindications to estrogen? (15 in 4 categories)
    • -Cardiovascular: 
    •   -blood clot (DVT, PT, arterial clot)
    •   -Migraine with aura >15 mins (vasospastic)

    • 1) infection
    • 2) Expulsion
    • 3) Perforation
    • 4) Irregular bleeding

  19. Describe the changes to the GI (3), derm (3), and MSK systems in pregnancy
    • GI: progestin is an anticholinergic so decreased transit causes constipation, delatey gastric emptying, gallbladder stasis
    • Derm: hyperpigmentation, striae, hair growth/loss
    • MSK: loose ligaments, more nerve compression (Bell's, Carpal), LBP, Symphyseal pain
  20. What is the most important modifiable risk factor associated with adverse pregnancy outcomes? What is the most common adverse event?
    Smoking. These people MUST quit. No matter what you need to do. Spontaneous abortion is the most common A/E
  21. How does smoking harm the baby? Is nicotine replacement harmful too?
    Nicotine is a molecular and cellular poison. Vasoconstriction impairs blood flow to fetus. It is, but the nicotine levels are MUCH lower than what you get with smoking

    at 24-28 weeks
  25. Describe the menstrual cycle. (no pregnancy)
    • Menstrual phase (variable (1-4 days))
    • Proliferative phase (variable days, estrogen-dependent)
    • 1) low E and P stimulates GnRH (and therefore LH and FSH) in this phase there is negative feedback
    • 2) LH increases progesterone (stolen and converted to estrogen by theca interna), FSH increases estrogen and stimulates 3-30 follicles
    • 3) estrogen builds up the endometrium thins cervical mucus
    • Ovulation
    • 4) suddenly E and P have a positive feedback cycle with LH and FSH causing the LH surge , which causes ovulation. Later the FSH surge happens
    • Luteal Phase (last 14 days)
    • 5) Theca interna goes with egg and theca externa (corpus luteum) is now free to make the progesterone without the theca interna stealing it as before.
    • 6) Switch back to negative feedback. Progesterone inhibits LH and FSH, causes endometrium to mature.
    • 7) Second set of follicles develop and cause estrogen to peak. They eventually regress due to atresia
    • 8) eventually the corpus luteum antrophies, causing the end of the progesterone release causing menses and the rise of FSH and LH, starting us over again.
  26. What phase are the eggs stuck in until they are chosen?
    prophase I
  27. Differentiate primary and secondary dysmenorrhea

    • 2) sperm undergo the capacitation and acrosomal reaction
    • 3) oocyte is fertilized and oocyte undergoes second meiotic division
    • 4) male and female pronuclei come together and make a zygote
  29. What happens to start menses in puberty?
    Gonadostat becomes less sensitive to the background estrogen and starts pulsing (at night), this releases LH and FSH which starts the cycle
  30. What are the stages pubertal development in order (5)
    • 1) Thelarche (breasts)
    • 2) Adrenarche (pubes)
    • 3) growth spurt

    -Cardio conditions (4 points)
    -Resp conditions (2)
    • -Cardio: Stenotic lesions get worse, regurge gets better (lower BP), pulm HTN means you shouldnt get pregnant, NYHA I-II do fine
    • -Resp: optimize asthma control, think of pregnancy induced causes of SOB
  273. Describe the important facts on these medical conditions in pregnancy:
    -Heme conditions (2 points)

  274. Describe the important facts on these medical conditions in pregnancy:
    -Gastro conditions (2 points)
    -Renal conditions (2)
    • -Gastro: if IBD in remission before preg, it will do fine; there are liver disorders specific to preg
