Q

Describe bimanual examination & possible results

A

Lubricate index & middle finger, enter with palm facing sideways then rotate so it is facing upwards;
Move along the posterior wall of the vagina and locate the cervix and feel for smoothness, clots, mobility and firmness
Place fingers in the posterior fornix to lift the uterus whilst simultaneously pushing the fundus down by placing the left hand above the symphysis pubis.

for early pregnancy: softening of cervix (Goodell’s sign), softening of isthmus (Hegar’s sign)

Q

what is nuchal translucency

A

measure thickness of subcu translucency between skin & soft tissue overlying cervical spine
if increase in thickness (1tri: >3mm, 2tri: >6mm) –> Down’s syndrome

1tri combined screening: maternal age, gestation, history of T21, nuchal translucency, PAPPA, free beta hCG
11-13 weeks; result in 2 weeks; 80-90% detection rate

2tri biochemical screening: biochemical marker: hCG, alpha-fetalprotein (AFP)
16-19 weeks; result in 2 weeks; 80% detection rate

17
Q

2nd tier non-invasive prenatal test (NIPT)

A

DNAtest of fetal chromosomal abnormalities eg trisomy 21 (Down). trisomy 18 (Edwards), trisomy 13 (Patau)
>10 weeks; result in 1 week; 90-99%

18
Q

Prenatal invasive diagnostic procedures (x3)

A

Chorionic villus sampling (CVS) –> chromosome, metabolic disorders ~11-13weeks

expulsion of the fetus either spontaneously or by induction
<24wks or weight <500g
10-15% abortion rates (reason unknown)

20
Q

Nursing care for threatened abortion

  • assess amount of bleeding (if
    increase & become bright red –> inevitable abortion)

bleeding, uterine cramping, n&v, headache, dizziness

23
Q

antepartum hemorrhage def

A

bleeding from genital tract after 28 wk of pregnancy

24
Q

common cause of antepartum hemorrhage

A

placenta praevia, abruptio, placenta, marginal hemorrhage, rupture of vasa praevia (fetal blood vessel lies over internal cervical os)

25
Q

determine 4 types of placenta praevia

A

I: minor/ low-lying placenta
II: marginal praevia (not covering internal os)
III: partial praevia (overlie os when closed, not completely when dilated)
IV: total praevia

26
Q

abruptio placenta def

A

bleeding from premature separation of whole/ part of a normally situated placenta from 34 week of pregnancy

27
Q

3 types of abruptio placenta

A

mild - minimal vaginal bleeding & changes in maternal vital signs; no fetal distress/ shock
moderate - concealed/ apparent bleeding, fetal distress, tense uterus & painful palpation
severe - maternal hypovolemic shock, may lead to fetal death

28
Q

difference in clinical features between placentia praevia & abruptio placenta

A

placenta praevia - uterus soft, tender
abruptio placenta - uterus hard, tense & tender; difficult to palpate fetal parts/ auscultate heart
