Q

what are first trimester screenings for mom and baby?

A
  • mom: entry panel
  • fetal: 1st trimester screen (NT/ PAPP-A, b-hcg)
  • these screening cover trisomy

Q

what are second trimester screenings for mom and baby?

A
  • mom: 1-hr glucola(roughly at 24-28 weeks), CBC, antibody screen
  • fetal: Triple/Quad screen (AFP, b-hcg , estriol/inhibin A)
  • If the first trimester screening was done, only check AFP in 2nd trimester

AFP- indicator for open neural tube defects (spina bifida)

Q

What are third trimester screenings for mom and baby?

A
  • mom: CBC (anemia) , Group B strep
  • PRN: depression, STI
  • Fetal: NST, BPP (keep an eye on fetal status, if the NST is not reactive—> complete BPP)

Q

What is another screening test that can be perfomed on mom and baby? Considered “advanced”

A

“Advanced screening test (NIPT, cell-free fetal DNA)

  • Maternal serum test
  • 10-20 weeks (optimal 11-13)
  • T21, 18, 13, and some sex chromosomes aneuploidies (limitations- T21 easier to detect than 13)
  • “near-diagnostic” DNA test
  • if multiples, can’t tell which twin is affected

If NIPT abnormal–> direct fetal tissue test

Q

What fetal diagnostic test can be completed at 10-15 weeks?

A
  • fetal: Chorionic Villi Sampling- can be done 1st trimester- sampling placenta
17
Q

what fetal diagnostic test can be completed at 15-20 weeks?

A
  • Fetal: Amniocentesis- abdominal or vaginally getting amniotic fluid (looking for sloughed cells w/in fluid)
  • can’t do too early, so you can get enough fluid
18
Q

in terms of fundus height, where do you expect the fundus to be at 12 weeks, 20 weeks, 36-38 weeks, 40 weeks?

A
  • 12 weeks: fundal height just above pubic bone; fundus meets pelvic brim
  • 20 weeks: fundal height is approximately at the level of her umbilicus
  • 36-38: fundus usually right up under sternum
  • 40 weeks: Fundus drops below 38 week level as presenting part drops down into pelvis
19
Q

what heatlth maintence is recommended for pregnant patients?

A
  • Influenza, COVID vacc
  • Tdap, vaccine (recommended every third trimester of every pregnancy)
  • PRN: RhoGAM, HSV prophylaxis
20
Q

when is RhoGam given? What is it for?

A
  • given at 28 weeks
  • RhoGAM is given when there is an RH- mom and RH + baby
  • can also be used for threatened abortions, trauma or potential for bleeding to help to stop body from making antibodies against RH+ blood
21
Q

What is a postive kick count?

A
  • At least 10 times in an hour = positive kick count
22
Q

what is considered a positive non-stress test?

A
  • Fetal HR response to fetal activity
  • Seeing at least 2 heart rate responses is positive, non reactive can usually goes onto biophysical profile
23
Q

what is the biophysical profile? How is it scored?

A
  • BPP: NST + ultrasound to look for fetal movement, overall tone and amniotic fluid index
  • scored 0-2 for each category: 8-10 =reassuring, 6= equivacal, 0,2,4= not reassuring, move toward delivery
24
Q
  • Preexisting
  • mild: 140-159/ 90-109
  • severe: 160/110
A

Chronic Hypertension

25
* After 20 weeks - no preexisting * 5-10% weeks * **no proteinuria**
Gestational Hypertension
26
* hypertension with proteinuria * multisystem involvement possible (implicates problems w/placenta, can include heart and other systems
Pre-eclampsia (Toxemia)
27
elevated BP + proteinuria + seizures
Eclampsia
28
* Hemolysis (anemic), elevated LFT, lower platelets(bleeding, DIC, abnormal blood counts) * can happen to patients with pre/eclampsia
HELLP syndrome
29
How do you workup patients with hypertensive disorders?
PE: BP, edema, heart, lungs, eyes (papilledema), abdomen(RUQ tenderness), Neuro (CNS instability), fetal status labs: CBC, BUN/CR, LFTs, ua, 24-hr urine, coags
30
what are acceptable medications to treat hypertensive conditions in pregnancy?
* methyldopa, a/b-blockers (labetolol), hydralazine, CCB (nifedipine)
31
what are acceptable medications to treat hypertensive conditions in pregnancy?
* methyldopa, a/b-blockers (labetolol), hydralazine, CCB (nifedipine)
32
what are not acceptable medications to treat hypertensive conditions in pregnancy?
* ACE-I, ARBS * Diuretics | can cause pregnancy loss
32
ex. of gestational diabetes complications
congenital anomalies SAB and stillbirth macrosomia polyhydraminos (excess amniotic fluid) placental abruption(big baby, big placenta) neonatal hypoglycemia
33
what is associated with postpartum hemorrhage?
* prolonged labor * precipitous labor (too fast and furious) * pre-eclampsia * multiple gestation * retained placenta * operative delivery * uterine atony (uterine muscle doesn't contract ) | can treat uterine atony with massage or medication
34
what factors are associated with preterm labor?
* smoking (Causes vascular inflammation) * short interpregnancy interval (uterus is not healed enough < 12-18 months) * UTI/ genital tract infection (inflammatory response) * periodontal disease (systemic inflammation)
35
what is associated with placental abruption?
* Gestation hypertension * prior placental abruption * multiparity * smoking * cocaine use * trauma * PT will present with: Bleeding, pain, "hard, board-like abdomen and tenderness"
35
What are primary factors to be considered to evaluate progression of labor?
* **Cervical effacement & dilation** * contraction frequency & intensity * fetal present part at the inlet
