What are the things to observe at the cervix during vaginal examination?

Answer 9

• open or close? (1st time moms: oval shape; otherwise slit)
• thicken
• bluish discolouration (Chadwick’s sign)

• any abnormal discharge/ bleeding

Question 10

Describe bimanual examination & possible results

Answer 10

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)

Question 11

Answer 11

CBC, ABO grouping, Rhesus factor (Rh), Rubella antibody, HepB surface antigen (HbsAg), Venereal disease (syphilis), Human Immunodeficiency Virus (HIV) antibody

ketone

Question 13

What to do if anti-Rh antibodies is tested positive?

Answer 13

give Rh anti-D immunoglobulin injection (Rogan) within 12hrs after delivery
(prevents hemolysis in baby)

Question 14

5 prenatal diagnosis for congenital abnormalities/ heredity condition

Answer 14

Biochemical screening
amniocentesis
chorionic villus sampling (CVS)
cordocentesis
fetoscopy

what is nuchal translucency

Answer 15

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

Question 16

1st tier non invasive screening test

Answer 16

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

Question 17

2nd tier non-invasive prenatal test (NIPT)

Answer 17

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

Question 18

Prenatal invasive diagnostic procedures (x3)

Answer 18

Chorionic villus sampling (CVS) –> chromosome, metabolic disorders ~11-13weeks
Amniocentesis –> AFP, Chromosome ~16-20weeks
Cordocentesis –> Chromosome, pH, anemia, infection, metabolic disorders 18-24 weeks

Abortion definition

Answer 19

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

Nursing care for threatened abortion

Answer 20

• assess amount of bleeding (if
  increase & become bright red –> inevitable abortion)
• advice high fiber diet to prevent constipation

Question 25

determine 4 types of placenta praevia

Answer 25

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

abruptio placenta def

Answer 26

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

Answer 28

placenta praevia - uterus soft, tender
