Q

Tell me more about quantitative beta hCG, GO!

A

Used to assess how the pregs is going
usually normal pregs hCG will double in count in about 2.5 days so you need to do another one in 3 days to compare values

34
Q

And again:

what is an ectopic pregnancy

A

Includes a pregnancy located anywhere OUTSIDE the endometrial cavity.

Can be in the part of the tube contained within the myometrium, fallopian tube, ovary, or on the bowel or the peritoneum

35
Q

How is ectopic pregs diagnosed

A

absence of an intrauterine gestational sac on a TRANSVAGINAL U/S once the quantitative hCG level reaches 1500

36
Q

which diagnostic tech RARELY identifies a gestational sac outside the endometrial cavity

A

U/S

37
Q

what happens during a preconception consultation

A
  1. identify risk factors (personal or in family)
  2. optimize pt medical status if medical risk factors are found (diabetes, HTN)
  3. current meds and safety in pregs
  4. Give prenatal vitamins prior to conception
38
Q

what risk factors from pt reproductive history is important to note bc of risk of REOCURRENCE

A
  • preterm labor or delivery
  • low birth weight
  • pre-eclampsia
  • stillbirth
  • congential anomalies
  • gestational diabetes
39
Q

what is the prenatal visit schedule like

A

Every 4 weeks until 28 weeks
Every 2-3 weeks at 28-36 weeks
Weekly from 36 weeks until delivery

Appointments may be closer if risk factors or ongoing medical conditions need closer monitoring

40
Q

which risk factor are most common in first pregnancy and should be check

A

HELLP/pre-eclampsia

41
Q

what do you except at a first prenatal visit

A
  1. complete HnP
  2. cultures and blood work
  3. everything in preconception counseling if not done before
  4. if previous cesarean - discuss circumstances and current delivery options
  5. if >35 at EDD - discuss risks/testing
42
Q

what is prenatal care mostly about

A

TRENDS! if pt is falling off the normal curve of trend, bring them back asap!

43
Q

Lab tests at first visit

A

CBC, blood type/Rh, GC/Chlamydia, pap smear, HBsAG, TSH, Urinalysis, HIV and Cystic fibrosis(if pt agrees for both), RPR (syphilis)

Rubella titer - can protect baby, but can’t vaccinate
Antibody screen

44
Q

why is antibody screening an important lab test

A

Erythroblastic fetalis: Tx for exposure of mother and fetal blood (trauma etc..) even if you don’t know baby’s blood type

45
Q

what needs to be done in subsequent visits

A 
maternal weight 
urine dipstick -for protein and glucose 
BP
fundal height 
fetal heart tones 
fetal presentation after 30 weeks --> Leopold's maneuvers
46
Q

whats the importance of maternal weight

A

average gain. body habitus effects on weight gain

  • underweight women gain weight to get to optimal preggers weight
  • overweight women actually LOSE weight to get to that optimal preggers weight
47
Q

when to measure fundal height

A

1st 12 weeks, 12-20wks, after 20 wks

48
Q

what is screened during the 1st trimester

A 
blood work (10-13wks gestation)
U/S (11-13 wks gestation)
49
Q

what do you look for in blood work in the 1st trimester

A
  • PAPP-A (lower than usual with fetal Down’s)

- Inhibin A, free beta subunit hCG, total hCG (higher than usual with fetal Down’s)

50
Q

what do you look for on U/S in the 1st trimester

A

nuchal lucency –> naturally occurring fluid space at the back of the neck
(thickening in this area associated with Down’s)

51
Q

what is screened during the 2nd trimester

A

2nd trimester (15-20weeks)

  • fasting blood sugar
  • trisomies and open neural tube defects
  • fetal U/S
52
Q

what is the screening test for trisomies and neural tube defects

A
  • Serum Alpha fetoprotein – still used for twins
  • Triple Screen (Alpha fetoprotein, HCG, Estriol)
  • Quad Screen (same as triple screen + inhibin A)
  • Penta Screen (same as Quad + ITA: invasive trophoblast antigen)
53
Q

what is combined screening

A

serum sequential, integrated (non-disclosure) screening.

This replaces 2nd trimester screening

54
Q

when do you use a diagnostic test for trisomies/ONTD (open neural tube defects)

A

screening tests for these are replaced by Diagnostic testing if there are high risk factors for these conditions

  • advanced maternal age
  • previously affected babies

also used when screening comes back with a higher than normal risk status

55
Q

so what is diagnostic testing for trisomies/ONTD

A
  • amniocentesis at 15-20 wks
  • chorionic villi sampling at 12-14 wks
    1. transabdominal
    2. transcervical
56
Q

what is cell-free fetal DNA

A

analyses fetal DNA in Maternal serum

it’s non-invasive - reliability that approaches amniocentesis or CVS (Chorionic villus sampling)

57
Q

when is cell-free fetal DNA done and why

A

can be done as early as 10 wks gestation

checks for trisomy 21, 18, 13

58
Q

what labs are done at 24-28 weeks

A

CBC
1hr 50gm Glucola test
Rhogram, if Rh neg (regardless of baby’s blood type)
vaginal culture (optional)

59
Q

what do you do if 1hr 50gm Glucola test is abnl

A

3 hr GTT, 100gm loading dose

60
Q

when do you give Rhogam

A

antepartum at 28 weeks, it has a 12 week lifesapn

post-partum if infant is Rh pos.

61
Q

Rh incompatibility occurs in …

A

Rh neg mothers

62
Q

what is Rh incompatibility

A

when maternal exposure to Rh pos. blood from teh fetus causes an antibody response in teh mother

63
Q

T/F; Rh incompatibility effects the first (exposure) pregnancy

A

FALSE; it effects future pregnancies

erythroblastosis fetalis (destruction of fetal red blood cells) => fatal fetal hydrops

64
Q

Rh incompatibility:

what are some feto-maternal hemorrhage sufficient to cause sensitization (alloimmunization)

A 
At the time of delivery – most common
Abruptio placenta
Bleeding placenta previa
Abdominal trauma
Amniocentesis
Ectopic pregnancy
Miscarriage
65
Q

RhoGam is passive or active immunity

A

passive immunity

66
Q

when should group B beta strep be cultured

A

35-36 weeks

67
Q

where is group B beta strep cultured from

A

lower 1/3 of vagina and rectum in the same culture medium

68
Q

T/F: group B beta strep should be treated in labor

A

TRUE; treatment in labor

69
Q

what are the risk factors of group B beta strep (GBBS)

A
  1. preterm labor
  2. preterm premature rupture of the membranes
  3. rupture of the membranes > 18 hrs
  4. temp >38C (100.4F)
70
Q

T/F: treat only those effected with GBBS

A

TRUE; treat ALL women, regardless of strategy who have:

  1. GBBS bacteriuria at ANY time in preggers
  2. given birth to an infant with GBBS
71
Q

intrapartum prophylaxis for GBBS

A
  1. IVPB penicillin G 5 million units initially and 2.5 million units every 4hrs until delivery
  2. IVPB Ampicillin, 2 gm initially and 1 gm every 4 hrs until delivery
72
Q

what do you give to moms who have GBBS but is allergic to penicillin

A

Now: request sensitivites as teh efficacy of Clindamycin and Erythromycin have been drawn into question

used to: empirically use Clinda and Erythro

73
Q

what are the older testing methods for fetal well-being

A

non-stress test (NST)
contraction stress test (CST)
Biophysical profile (BPP)

74
Q

what is NST

A

testing thats done after 28 weeks
fetal heart beat will go up 15 beats for a few seconds with movement and that’s normal

-this test means that adequate oxygen is required for fetal activity and heart rate to be within normal ranges. When oxygen levels are low, the fetus may not respond normally

75
Q

what is CST

A

The aim is to induce contractions (usually 3) and monitor the fetus to check for heart rate abnormalities.

stimulate uterine contractions:

  • nipple stimulation
  • IV pitocin (oxytocin)
76
Q

what is the newest testing for fetal well-being

A

Cord Doppler Velocimetry (CDV) :

-Used largely in pregnancies at risk for FGR (fetal growth restriction, AKA IUGR).

77
Q

What does a normal CDV mean

A

Normal cord doppler studies indicate forward motion of blood flow both in systole and diastole.

78
Q

What does an abnormal CDV mean

A

Abnormal cord doppler studies indicate increased placental resistance to blood flow that results in either absent or reversed blood flow during the end-diastolic phase

79
Q

whats the damn purpose of pre-natal visit

A
  • pt education
  • evaluation for presence/development of preg risk factor
  • assuring fetal well-being
  • look at developing trends**
80
Q

What should you be thinking when approaching preg pt

A

dang you HUGE!

  • Proving to yourself that the baby is better off left in-utero,
  • The benefits of leaving the baby in-utero outweigh the risks of delivery.
  • It’s not just about the numbers and the trends!
