What is the fertilized ovum called when it enters the uterus? What does it do?
blastocyst;produces human gonadotropin (hCG), which stimulates the corpus luteum to continue making progesterone. It causes a small amount of bleeding when it implants to the uterine wall.
Talk about the placenta and what it does at certain weeks
Week 7: it supports the corpus luteum with pregnancy by producing progesterone
Week 10: completely takes over the corpus luteum by producing progesterone
What type of organ is the placenta? What does the placenta produce?
Endocrine organ; produces several hormones to aid in growth and maintenance of the fetus and direct changes in the woman’s body to prepare for birth and lactation
What does hCG do? Name four things
- Stimulates the rise in progesterone
- Supports the corpus luteum
- Supports deep implantation of the placenta into the uterine wall
- Helps maintain viability of the fetus
What does progesterone do? Name three things
Maintains the endometrium around the fetus
Increases the alveoli in the breast
Keeps the uterus in a quiescent (inactive) state
What does estrogen do?
Stimulates the duct formation in the breasts, increases the weight of the uterus, and increases certain receptors in the uterus that are important at birth.
How long does pregnancy last?
280 days from the first day of the last menstrual period (LMP)
(40weeks), 10 lunar months/9calendar months
Why does pregnancy include 9 calendar months but 10 lunar months?
The 10 lunar months include the 2weeks when the follicle was maturing but before conception actually occurred.
How is pregnancy divided up?
Trimesters:
1st: first 12 weeks
2nd: week 13-27

What are the three types of s/s of pregnancy?
Presumptive: amenorrhea, n/v, breast tenderness, fatigue, urinary frequency
Probable: those detected by examiner (enlarged uterus)
Positive signs: direct evidence= fetal heart tones (FHT) or cardiac activity with ultrasound
How many days after conception before the hCG serum becomes positive after the blastocyst implants into the uterus?
8-11 days after conception
What s/s may a woman experience during the first trimester?
Breast tingling and tenderness with mammary growth, n/v, fatigue
What do estrogen and progesterone cause during the first trimester?
Hypertrophy of the uterine muscle cells, uterine blood vessels and lymphatics enlarge
What shape is the uterus during pregnancy? What causes urinary frequency?
Globular; the uterus compresses the bladder
What happens to the blood pressure during the first trimester?
Drops in the 7th week until midpregnancy r/t falling peripheral resistance.
Returns to baseline gradually by term
During which week of the embryonic period does the fetal period begin?
9weeks
At which week range can FHT be heard? What device can you hear it with?
9-12weeks; Doppler imaging
At which week can the uterus be palpated just above the symphysis pubis?
12weeks
At which weeks do the n/v subside? What does a woman experience during the second trimester?
After weeks 12-16, n/v improve.
Second trimester: women experience fetal movement (quickening), breast enlargement, colostrum from nipples, darkening of areole and nipples, linea nigra and striae gravidarum
