Babies

Question 1

vision in 3rd trimester

Answer 1

responsive

Question 2

gestational period is the development of which stage?

Answer 2

sensorimotor

Question 3

fetal growth

Answer 3

first half - 10% full term weight - hard to recognize
second half - rapid increase
last three weeks - slowed growth - prepare itself before it gets expelled

Question 4

labour 2

Answer 4

delivery of baby

urinary contractions that expel the fetus and placetal wall

Question 5

prep for labour 2

Answer 5

fetus gets smaller

women prepares for uterine contractions - changes in body, false contractions

Question 6

labour length

Answer 6

15-18 hours, first child is usually longer, after its half the time

Question 7

why is average labour generally longer now? 3

Answer 7

mother increase in age(culture), increase body fat %
baby, increase in weight of first baby
doctor - emergency c-sections and epidurals - lack of sensation

Question 8

four stages of labour

Answer 8

1. dilation and effacement
2. baby emerges
3. placenta needs to be expelled (afterbirth)
4. immediate postpartum

Question 9

Dilation and effacement

Answer 9

2-3 weeks with early contrations before called LATENT LABOUR
ACTIVE labour has true dilation - water breaks
pressure against uterus - cervix causes it to dilate - enlarge and efface - thin out
affected ROM, woman can feel it
mucal plug - cervical opening

Question 10

before active labour starts

Answer 10

placental wall has to open

Question 11

normal presentations of the baby

Answer 11

ant - spine to stomach
pos - spine to spine
transverse - left or right

Question 12

What comes out first in normal presentations

Answer 12

portion of the head because its cartilagenous - the vertex - meeting of sutures

Question 13

Whats not normal

Answer 13

5-6%, vertex doesnt come first and larger surface area

Question 14

atypical presentations

Answer 14

brow
face
shoulder
breech - legs straight up or hugged - frank breech, butt down
- complete breech, bent knees
-footling breech, feet first, head last - long time in birthing canal which is bad

Question 15

delivery refers to

Answer 15

latent and active labour

Question 16

birth difficulties 2

Answer 16

precipitous delivery

prolonged labour

Question 17

precipitous delivery

Answer 17

less than 3 hours
not dialated enough, cervix and uterine lining not prepared, medical situation/environment
skull bones rapidly compressed - unattended birth

Question 18

prolonged labour

Answer 18

only refers to active labour
more than 24 hours
increased chances of infection, suffocation and decreased O2
the baby is in the birthing canal and has left aqueous environment - now theres a delay into the airboure because you need to cut the umbilical cord.

Question 19

adjustments at birth

Answer 19

cardiovascular system interaction with the respiratory system which was used minimally as they relied on the mother’s system through the umbilical cord

Question 20

internal respiration age of viability

Answer 20

week 25 0 properly function

Question 21

fetal development of CVS heart

Answer 21

week 3 - 2 endocardial tubes that fuse into the primitve heart tube
week 5 - it folds, twists and partitions into 4 chambers and development of blood vessles
week 9 - blood vessels establish

Question 22

congenital heart disease

Answer 22

born with it  1/5000 
holes between chambers 
incorrect number of valves 
complete absence of chambers 
can be detected and treated

Question 23

fetal development of lungs

Answer 23

4 weeks - single pouch
16th week - bronchiole tree
3rd trimester - alveoli begin - not fully developed till after we are born

Question 24

fetal lungs are protected by 3

Answer 24

foramen ovale, ductus arteriosus and ductus venosus

Question 25

why do fetal lungs need protection?

Answer 25

too fragile to handle forces

Question 26

fetal blood gets sent to

Answer 26

right heart but mostly oxygenated anyway, shunted by left and right atrium as instead of sending all blood to RV, some brought to left atrium so not everything goes to the lungs

Question 27

ductus arteriosus

Answer 27

opening into aorta from right ventricle to lungs, reduce the amount of blood going to the lungs - closes within 30 mins of being born

Question 28

ductus venosus

Answer 28

all blood wants to go to the liver but DV shunts away good blood from liver and sends it to systems that need it

Question 29

At birth, without the umbilical cord

Answer 29

increased aortic pressure
lungs expand - connection of inhalation with cardiovascular system
ductus venosus doesnt close right away, may last up to a week
