maternal malnutrition associated with…

A
  • low birth weight

- intellectual and social deficits

17
Q

Effects of environmental hazards depend on:

A
  • timing
  • severity and duration
  • genetic makeup of child and mother
  • postnatal environment
18
Q

Stage 1 of labour

A
  • dilation of cervix begins
  • contractions are greatest and cervix opens completely
  • (9 hours for first baby)
19
Q

Stage 2 of labour

A
  • baby’s head appears
  • baby passes through
  • 1,5 hrs
20
Q

Stage 3 of labour

A

expulsion of the placenta

21
Q

Baby during labour

A
  • releases stress hormones and adrenalin to help baby through birth and after.
  • increases metabolism which increases blood flow
22
Q

APGAR test

A
  • used to provide quick assessment of the newborn’s heart rate, respiration, colour, muscle tone and reflexes
  • 0-2 (2 the highest)
23
Q

APGAR stands for…

A
  • Activity
  • Pulse
  • Grimace
  • Appearance
  • Respiration
24
Q

Neonates at risk

A
  • premature infants (born before 37 weeks)

- Low-birth-weight babies (less than 2500g at birth)

25
Q

Potential problems with neonates at risk

A
  • respiration
  • maintaining body t–emperature
  • immune system
  • digestion
  • parent-infant relations
  • Haven’t developed insulating layer of fat
  • Digestive system is immature
  • Parents feel less confident and scared of hurting it
26
Q

4 components of Kangaroo care

A
  1. Kangaroo position (skin-to-skin contact)
  2. Kangaroo nutrition (breastfeeding)
  3. Kangaroo support
  4. Kangaroo discharge
27
Q

Benefits of Kangaroo Care

A
  • Improves survival
  • Infants calmer, less distressed
  • Infants show improved cognitive performance
  • Mothers feel more positive
  • Improves quality of parent-child and family interactions

  • Parents body just as effective as an incubator. -Keeps warm and protects from infections
  • Mothers body produces antibodies from germs and passes them on to baby through milk and skin
  • More organised sleeping and waking patterns.
  • Some think to be used to all babies to improve development and parent attachment.
28
Q

Infants’ early capacities

A
  • newborn reflexes
  • sensory capacities
  • cute
  • crying
  • smiling
  • all help to facilitate close parent-child relationship
29
Q

rooting reflex

A

automatically turn the face toward the stimulus and make sucking (rooting) motions with the mouth when the cheek or lip is touched. The rooting reflex helps to ensure successful breastfeeding.

30
Q

grasping refelx

A

a flexion of the fingers caused by stimulation of the palm of the hand. The reflex is present at birth and usually disappears by 6 months of age.

31
Q

Sucking reflex

A

When the roof of the baby’s mouth is touched, the baby will begin to suck. This reflex does not begin until about the 32nd week of pregnancy and is not fully developed until about 36 weeks. Premature babies may have a weak or immature sucking ability because of this.

32
Q

Moro reflex

A

an infantile reflex normally present in all infants/newborns up to 4 or 5 months of age as a response to a sudden loss of support, when the infant feels as if it is falling. It involves three distinct components:

spreading out the arms (abduction)
unspreading the arms (adduction)
crying (usually)

33
Q

Post natal depression

A
  • affects about 13% of new mothers

- risks increased for those with a history of depression, other life stresses, lack of social support

34
Q

depressed mothers may…
