Q

Probable sign (think doctor):

A

Abdominal enlargement, Hegar’s sign (softening and compressibility of lower uterus), Chadwick’s sign (violet bluish color of cervix and vaginal mucosa), Goodell’s sign (softening of cervical tip), Ballottement (rebound of unengaged fetus, think BALL), braxton hicks contractions, positive pregnancy test

23
Q

Positive sign (think baby, objective):

A

the baby is seen (4-6 weeks), heard (10-12 weeks), and felt (20 weeks). Heard fetal heart tones, felt fetal movement by the provider, seen by an ultrasound

24
Q

Implantation cycle:

A

Conception occur in the FALLOPIAN TUBES
Fertilized ovum gets IMPLANTED in the uterus between 6-10 days Implantation occurs 6-10 days
Sperm survives 24-48 hours
During implantation, you can have some bleeding

25
Q

Nutrition during pregnancy (which will need further teaching):

A

Folic acid: prevent neural tube defects
Protein: needed for tissue growth
Omega 3’s: needed for brain development for the growing fetus

Calcium: 1000 mg/day
Fluids: 8-10 glasses (2.3L)
AVOID unpasteurized milk, unwashed fruits/veggies, liver, raw fish/meat, high mercury, alcohol

26
Q

Advanced maternal age >35 year/ is at risk for:

A

Down syndrome baby trisomy 21

27
Q

Umbilical cord contains:

A

2 Arteries, 1 Vein

28
Q

STI counseling:

A

Ask about past exposures

29
Q

What does smoking during pregnancy do to fetus?

A

Fetus will be at risk due to decreased blood flow to placenta, placental abruption, preterm delivery

30
Q

know probable signs of pregnancy, which comes first?

A

Abdominal enlargement
Hegar’s sign (softening and compressibility of lower uterus)
Chadwick’s sign (violet bluish color of cervix and vaginal mucosa)
Goodell’s sign (softening of cervical tip)
Ballottement (rebound of unengaged fetus, think BALL)
braxton hicks contractions
positive pregnancy test

31
Q

What is leukorrhea, is this normal?

A

Yes, normal during pregnancy

32
Q

Foods for iron deficiency:

A

Lean meats, eggs, cheese, milk, nuts, legumes, green leafy veggies

33
Q

Pt dx with genital herpes, which will indicate further teaching:

A

there’s no cure, but acyclovir can suppress

34
Q

What to assess with a biophysical profile?

A

BPP is a non invasive test that combines NST and fetal ultrasound to assess fetal movements, fetal breathing, muscle tone, amniotic fluid, and NST (you want this reactive)

35
Q

When is a baby’s heart audible with a Doppler?

A

10-12 weeks

36
Q

Who would doctor order maternal serum alpha-fetoprotein/MSAFP?

A

All patients

37
Q

Why do we order MSAFP?

A

Screening occurs between 15-22 weeks, used to rule out down syndrome and neural tube defects.

38
Q

Condom teaching:

A

Place condom on erect penis, leaving an empty space at the tip for sperm reservoir
Following ejaculation, withdraw penis from vagina while holding the rim of the condom to prevent semen spillage
Can use in conjunction with spermicidal gel to increase effectiveness
Check expiration date prior to use
Latex and polyurethane condoms protect against STI
Only water soluble lubricants should be used with latex condoms to avoid condom breakage

39
Q

Amniocentesis:

A

Done after 14 weeks to test for genetic disorders, congenital anomalies (neural tube defects), and assessment of fetal lung maturity (for amniocentesis)

RhoGAM should be administered to Rh negative mother, this covers any chance of blood mixing

Complications for mom: infection, hemorrhage, placental abruption

Complications for baby: infection, injury from the needle

40

Cord compression
Head compression
Okay
Placental insufficiency

Management:
