NR 602 Midterm Study Guide Presumptive Signs of Pregnancy (ANS - Amenorrhea, N&V, breast tenderness or changes, deepening pigmentation, urinary frequency, fatigue, increased basal body temperature, and quickening (at 16 weeks).
Probable Signs of Pregnancy (ANS - Goodell's sign (cervical softening at 4wk), Chadwick's sign (blue color of vagina & cervix at 6-8 wk), enlarged uterus, (+) urine or blood pregnancy test.
Positive Signs of Pregnancy (ANS - Palpation of fetus, ultrasound visualization of fetus, and fetal heart tones.
12 week Fundal Height (ANS - The fundus should be at the level of the symphysis pubis
16 week Fundal Height (ANS - The fundus should be between the symphysis pubis and umbilicus
20 week Fundal Height (ANS - The fundus should be at the level of the umbillicus
25-35 week Fundal Height (ANS - The fundus should measure from the symphysis pubis and correlate with with gestational week (+/- 2 cm)

Naegele's Rule (ANS - Add 7 days to LMP, subtract 3 months, add 1 year; Used to calculate due date
Tier 1 Birth Control (ANS - Fail rate <1%; IUD, DMPA (Depo), Progestin implant, sterilization
Tier 2 Birth Control (ANS - Fail rate 2-3%; OCP, COC's, transdermals, cervical ring.
Tier 3 Birth Control (ANS - Fail rate roughly 20%; Barrier methods, can protect against STIs
Caldwell-Moloy Classification
(ANS - Four basic pelvic types: gynecoid, android, anthropoid, and platypelloid
FSH(follicle stimulating hormone)
(ANS - Gonadotrophin: targets the ovaries, where it stimulates the growth and
development of the primary follicles and results in the production of estrogen and progesterone.
LH (Luteinizing Hormone)
(ANS - Gonadotrophin: targets the developing follicle within the ovary; it is
responsible for ovulation, corpus luteum formation, and hormone production in the ovaries.
- / 3
Hypothalamus (ANS - Releases gonadotropin-releasing hormone (GnRH) in a pulsatile manner to initiate negative feedback system. Stimulates gonadotrophins->FSH&LH release-> Estrogen/Progesterone release-> Pituitary gland notes Estrogen/Progesterone levels and regulates the cycle by altering further FSH/LH release.
Ovarian Cycle (ANS - The 28 days of the menstrual cycle as they apply to events in the ovary.
The ovarian cycle has three subphases: the follicular phase, ovulation, and the
luteal phase.
Follicular Phase (ANS - The first phase of the ovarian cycle, during which a follicle (an oocyte and its surroudning cells) enlarges and matures. This phase is under the control of FSH from the anterior pituitary, and typically lasts from day 1 to day 14 of the menstrual cycle. The follicle secretes estrogen during this time period.
Ovulatory Phase (ANS - The second stage of the general menstrual cycle, when the mature ovum is released. Approximately 10 to 12 hours after the LH peak
Luteal Phase ANS - The third phase of the ovarian cycle, during which a corpus luteum is formed from the remnants of the follicle that has ovulated its oocyte. The corpus luteum secretes progestrone and estrogen during this time period, which typically
