breast changes
6th week- increase in vascularity associated with a sensation of heaviness, tenderness 8th week- nipple and areola become more pigmented, and montgomery tubercle become more prominent 16th week- colostrum 20th week- further pigmentation and mottling of the areola
26
relaxin
One of the effects of relaxin is the loosening of ligaments throughout the body, making pregnant women less stable and more prone to injury, especially in their backs
27
sensation of fetal movement
usually begins at 20 weeks in the primagavida or 17/18 weeks in the multipara
28
lightening
"dropping" late in pregnancy when fetus descends into lower pelvis
29
when should healthy pregnant pts come in for first apt?
8-10 weeks
30
urine hcg (when positive, what can cause false negatives)
- positive ~4 weeks - false negatives can be from being done too early or dilute urine
31
ultrasound time line (transvag, abd)
transvaginal 4-5 weeks gestation- sac 8-10 weeks- dating abdominal- after 1st trimester
32
what is increased if the yolk sac is larger than 7 mm without signs of a developing fetal pole?
increased chance of abnormal pregnancy
33
goals of prenatal visit
-increase probability of a healthy baby without maternal compromise -determine health of fetus and mother -determine gestational age of fetus -initiate a plan of continuing care -focus on risk assessment
34
prenatal visits: when and how often
-ideally initail visit before conception -less than 28 weeks=every month -28-36 weeks= every 2-3 weeks -36 weeks= once per week until delivery if pregnancy is uncomplicated
35
prenatal care timeline for labs and diagnostics
first visit: -pap smear, Rh screen, std screen, other labs weeks 8-12 -1st sonogram, amniocentesis, noninvasive prenatal testing weeks 24-28 -diabetes screen****, cbc week 36 -group B strep culture
36
gravidity
total number of pregnancies (if twins G=1)
37
parity
outcome of pregnancies
38
determining gestational age
count the number of weeks and days from last menstrual period ~40 weeks
39
positioning of pt during ob exam
-gown opening in front -semi sitting position with knees bent for pelvic exam **dont lay all the way flat as can compress descending aorta and inferior vena cava -all other exams procedures should be done in sitting or left side lying positions
40
cervical brush (cytobrush)
DO NOT USE ON PREGNANT PATIENTS may cause bleeding
41
gestational HTN
systolic- over 140 diastolic- over 90 occuring after wk 20 without proteinuria that resolves by 12 weeks post partum
42
chronic HTN
systolic = over 140 diastolic= over 90 before pregnancy, before wk 20, and after 12 wks postpartum
43
preeclampsia
systolic= over 140 diastolic= over 90 after wk 20 WITH PROTEINURIA
44
first trimester weight loss
shouldnt exceed 5% of prepartum weight
45
thyroid gland and pregnancy
inspect and palpate as modest symmetric enlargement is suspected
46
what does facial edema after 24wks GA indicate?
gestational HTN
47
mammary souffle
the mammary souffle is commonly heard during late pregnancy or lactation, is strongest in the second or third intercostal space at the sternal border bilaterally, and is typically both systolic and diastolic, though only the systolic component may be audible.
48
diastolic murmur in pregnancy
A diastolic murmur in pregnancy is never normal and should be investigated further.
49
what to listen for when auscultating heart during pregnancy
Listen for a venous hum or a continuous mammary souffle that are common in pregnancy due to circulation
50
when is the uterus at the level of the umbilicus?
20 weeks
51
uterine contractility before 37 weeks
before 37 weeks regular contractions with or without bleeding is abnormal = preterm labor
52
fundal height greater than 4 cm
consider large fetus, extra amniotic fluid, or uterin leiomyoma
53
fundal height less than 4 cm
consider missed abortion, transverse lie, growth retardation or false pregnancy
54
what to check with the cervix during bimanual exam
-effacement= degree to which cervix has thinned (4cm is unchanged or unaffected) -dilation
55
where is FHR best heard when head down and when breech
head down= best heard in LLQ breech=best heard in RUQ
56
normal doppler FHR
120-160 bpm
57
fetoscope
a special stethoscope used to hear FHR after 20 weeks
58
4 parts of leopolds maneuvers
1= determine what fetal part occupies the fundus 2= determines what side is the fetal back 3= identify descent of the presenting part 4=identify the cephalic prominence *from 28th week on these provide useful info to assess the lie and presentation of the fetus
59
fetal lie
relationship of the long axis of the fetus to the mother -longitudinal lie vertex presentation -longitudinal lie breech presentation -transverse lie shoulder presentation
60
fetal presentation
vertex presentation, breech presentation, shoulder presentation *normal presentation= vertex
61
leopolds 1st maneuver
-used to determine the fetal part that is in the uterine fundus -buttocks feels firm but irregular -the head feels hard and may be movable
62
leopolds 2nd maneuver
-locate the position of the fetal back -on one side the back will be rounded and firm -on the other side the limbs will be irregular, lumpy, and mvmt may be felt
63
leopolds 3rd maneuver
-palpate the lower pole of the fetus -if lower pole is not engaged moveable part will be felt
64
leopolds 4th maneuver
-performed to confirm the presenting portion and to located the side of cephalic prominence
65
pregnancy nutritonal rules
-3 meals a day -add extra 300 cals beginning 2nd trimester -rx multivitamin with atleast 400 mcg of folic acid per day CAUTION AGAINST -soft cheese -deli meats/cold cuts -excessive amounts of vitamin A -seafood
66
pregnancy weight gain
low bmi=28-40 lbs normal bmi= 25-25 lbs high bmi=15-25 lbs obese=15 lbs women carrying twins= 35-45 lbs young adolescents=upper end of range short women= lower end of range
67
exercise after 1st trimester
NO exercise in supine position
68
what vax should all pregnant women be up to date on?
tdap and flu vaccines
69
if indicated pregnant women may have what vax
-pneumococcal -meningococcal -hep B
70
concluding prenatal visits
