No its too close together with too much variablility, will need genetic testing upon birth

Q

4 stages of prenatal care

A
  • Preconception care (basic medical care esp. for those with chronic medical conditions and staying up to date on vaccines)
  • prompt diagnosis of pregnancy (confirm they didn’t read an at home test wrong)
  • initial presentation for pregnancy care (initial pelvic exam, height of fundus, etc)
  • followup prenatal visits

Q

12, 14-16, 20, 24, 28, 32-36, 36-40, 40+ week visits

A
  • 12 (review prenatal lab tests, assess fetal heart beat with doppler)
  • 14-16 (assess growth, order some genetic tests and order amniocentesis)
  • 20 (auscultate fetal heart with fetoscope (old school) ultrasound for fetal anatomy)
  • 24 (maternal education and review signs and symptoms for preterm labor)
  • 28 (repeat antibody screens, administer Rh immune globulin, perform glucose screen, perform cervical assessment, TDaP administration)
  • 32-36 (assess the cervix, GBS culture)
  • 36-40 (assess fetal position, cervical exam for dilation each visit)
  • 40+ (perform cervical assessment, institute fetal surveillance, typically WILL induce by end of 41 weeks)

Q

Weight gain during pregnancy

A

a woman at ideal body weight requires total 24-28 lb weight gain, less for those over or more for those under ideal weight to meet goal requirements (might have to modify diet)

20
Q

Weight loss during pregnancy is not advised except in those with…

A

…very high BMI

21
Q

Weight retention after pregnancy

A

Average retained pregnancy weight of 3 lbs, see loss over 6 months progressively due to natural diuresis of excess volume

22
Q

Smoking and pregnancy complications (6)

A
  • bleeding
  • premature birth
  • low birth weight
  • neonatal absence syndrome
  • congenital anomalies
  • low IQ of childhood
23
Q

Alcohol and pregnancy complications (2)

A
  • low birth weight

- fetal alcohol syndrome

24
Q

Best advice regarding alcohol and pregnancy

A

Complete abstience

25
Q

Fetal alcohol syndrome features (6)

A
  • growth restriction
  • behavioral disturbances
  • brain defects
  • cardiac defects
  • spinal defects
  • broad upper lip, facial distortions
26
Q

Caffeine in pregnancy

A

Ideally none, but risks not as obvious as smoking and alcohol

27
Q

Cell free fetal DNA (cffDNA)

A

A maternal phlebotomy study that is often done on screening in the first trimester to determine sex of child and test for aneuploidy, these DNA fragments increase in conc. in bloodstream thruout pregnancy and quickly diminishes upon delivery

28
Q

Nucchal fold translucency

A

Ultrasound screen done most often in the first trimester to visualize fetus, can be found alone in 62% of down syndromes and 30% of spontaneous abortions

29
Q

AFP testing

A

Alpha fetoprotein, a sometimes recommended 2nd trimester screen that finds 20% of down syndrome patients and neural tube defects

30
Q

Pregnancy associated protein A (PAPPA)

A

Screening done during first trimester alongside nucchal fold translucency on ultrasound to increase rate of determining presence of down syndrome (positive in both up to 73% certainty)

31
Q

Amniocentesis

A

a relatively low risk .5% of fetal loss test done during 2nd trimester for chromosome analysis, AFP, DNA markers, etc, not done as screening but for diagnosis and evaluation

32
Q

Work conditions which increase risk of low birth weight, preterm labor, and delivery (4)

A
  • physically intensive employment
  • standing for long periods of time
  • increased pulling, pushing, or lifting
  • decreased rest periods
33
Q

Recommended favorable working conditions for pregnant women (4)

A
  • only 8 hour shifts
  • no more than 48 hrs a week
  • limit work between 6am and midnight
  • avoid jobs that require good sense of balance
34
Q

Saunas, hot tubs, and whirlpools use while pregnant

A

Advise not to use while pregnant, temp already elevated by the baby

35
Q

Travel while pregnant

A

Best taken during 2nd trimester, many airlines have regulations

36
Q

Common pregnancy complaints and how are they treated? (8)

A
  • nausea and vomiting (first trimester usually resolves 16 weeks, morning sickness), treated with zofran
  • constipation, treated with bulking agents (mirilax)
  • hemorrhoids, treated with prevention or topical anesthetic
  • fatigue (particularly early on), supplemental iron if anemic
  • urinary frequency or incontinence (differentiate from rupture of amnion also known as water breaking), treated with kegals
  • headaches, treated with acetaminophen
  • syncope (due to blood flow to fetus does see drastic drop in blood pressure), treated with resting in lateral recumbent position, change position gradually, hydrate
  • edema (common, as long as bilateral can be physiologic and not concern for DVT or heart failure and is relieved by raising legs)
37
Q

Live vaccines and pregnancy

A

Contraindicated (MMR, V, and live influenza!)

38
Q

Nulligravida

A

Never having been pregnant

39
Q

Nullipara

A

Never having given birth

40
Q

In measuring the fundus, if smaller than expected may be due to these 2 conditions. If larger, than these 3

A
  • earlier gestation
  • oligohydraminos
  • later gestation
  • polyhydramnios
  • twins
41
Q

Intrauterine growth restriction

A

When the unborn baby is smaller than it should be because it is not growing at a normal rate inside the womb, putting it at risk of certain health problems and complications during pregnancy (potentially even death), delivery, and after birth

42
Q

Quad screen

A

One lab test performed in patients prenatal care based on history at 15-19 weeks, includes AFP, hCG, estriol, and inhibin A to assess neural tube defects and genetic defects

43
Q

Group B infection in neonates vs 1 month old

A

Because it is ubiquitous and commensal with mother not generating antibodies, the 1 month old is too often colonized and asymptomatic but neonates do not have immune function and can get septic from infection

44
Q

Standard of care for screening in first trimester (2)

A
  • ultrasound

- blood test for pregnancy associated protein A

45
Q

Chorionic villous sampling

A

Removal of part of the placenta to take for chromosomal testing either abdominally or vaginally, NOT often utilized because of high risk of fetal loss and is pretty much obsolete

46
Q

Exercise while pregnant

A

Good 3-4x a week but not starting anything new they haven’t already been doing, should avoid hot humid conditions or when febrile, sports injuries much higher due to ligmaent tissue loosening due to circulating relaxin levels

47
Q

Round ligament pain in pregnancy

A

Prior to 28 weeks can have a lot of pain especially on the right side as it is pulled and hurts with activity but subsides with rest differentiating it from acute appendicitis
