Maternal Exam 2 Flashcards
Changing body system during pregnancy
reproductive Gastrointestinal muskelosketal cardiovasular respiratory renal/urinary endocrine
Changes to the abdomen
- Uterus enlarges and muscle of abdomen stretch and lose tone.
- In 3rd tri the rectus muscle may separate
- Line of pigmentation down belly=Linea Negra
- Stretch marks=Striae
- Umbillical flatten or sticks out
Probelms with stomach
- delayed emptying from pregetrone on smooth muscule motility
- Galbladder may becaome distended, galstones are common in 2nd and 3rd tri.
- Kidneys are enlarged
- Colon is shifted upward and peristalticactivity decreases= constipation/gas
How to help the GI and stomch keep going?
Lots of water, fiber and exercise
Hyperplasia
New cell formation
Hypertrophy
Stretching in 2nd and 3rd tri.
Uterus grows from 10mls to ?
5000mls in 40 wks
contractions of the uterus when in practice?
Braxton hicks are
Chadwicks sign?
When the cervix turns a purplish/ blue color
Goodell’s sign?
Connective tissue that is softened
what holds everything into the uterus?
Cervix
What changes about the uterus?
hyperplasia/hypertrophy
moves from pelvis to abdomen
contractility
cervix- chadwicks and goodell’s sign
Uterus changes in size from…
2oz- 2.5lbs
What does estrogen do to the vagina and vulva?
increases vascularity, softening and thickening of mucosa
Leukorrhea?
increased vaginal secretions which are thick , white and acidic, the acidic environment discourages bacterial growth but can make some people more prone to yeast infections
Why is ovulation interupted during pregnancy?
B/c of the elevated levels of estrogen and progesterone, blocking the secrection of FSH and LH.
Corpus luteum produces?
hormons and disintegrate slowly.
The ovaries produce?
Progesterone until placenta takes over at 6-7 wks
the cervix is used to?
Keep baby in and keep bacteria out.
Endocervical gland secret?
thick, sticky mucous that forms a mucous plug and seals the endocervical canal
Increase vascularization in cervix causes?
Purple/ blue color and softening
What stimulates the glandular tissue of the cervix?
Estrogen
Colostrum is? When does is produced?
Thick, sticky yellow discharge from nipples that come before milk at the end of pregnancy
Changes effecting breasts?
Increased vascularity, and in response to luteal and placental hormones the lactiferous ducts proliferate increasesing in size and number ( bigger by 2-3 times)
Why do boobs get saggy after baby?
Increased glandular tissues displaces connective tissue and as a result the tissue becomes softer and looser
Areola of the nipple looks like?
Becomes dark in color and bigger in diameter, more erectile and montgomery tubercles develop on them as small white pimples, these secret oil to keep nipples drying out so dont pick or pop them.
Visably breast will have what on them?
Blue veins due to mammary vascularization that has increased and the veins are engorged and visible through skin( some striae may appear)
What happens to your cardiovascular system?
Increased blood volume
Increased Blood components
Increased cardiac output and hear rate
Decreased BP
Cardiac output is increased when?
In the early pregnancy and peaks at 25-30wks and is 30-50% high then normal.
Blood volume increases due to?
increased erythrocytes and plasma, it is solo important to drink plenty of water!
Changes to heart?
- rate may increase by 10-15 bpm at term
- Heart works harder to accomadate the increased HR and stroke volume required for the extra volume.
Blood pressure should be?
Slightly lower in pregnancy( from the peripheral vasodilation from the progesterone)( porgeterone relaxes muscles so BP is lower) and go back to normal in 3rd tri.
What is supine hypotension syndrome?
Uterus putting pressure on inferior vena cava, and causes dizziness, pallor, and clamminess, correct this by NOT laying on back and if you must for surgery place wedge or towel under back.
Blood components increase by?
RBC’s by 30% and Blood volume by 50% which cause anemia which we need iron to form hemoglobin for transporting oxygen, Hmg and Hct levels will be lower because they are diluted.(Iron supplement and lots of H2O.
Why is pregnacy a hypercoagulable state?
Increased vascularity makes person hemorage risk but the body produces increased amounts of fibrin and plasma fibrinogen but that causes risks for clotting
