Q

CONCEPTION THE FIRST STAGE

A

-age of conception is getting higher in Canada
-rates of triplets, quadruplets and quintuples has increased over 230% since the mid 1990s
-AMA is becoming an increasingly common phenomena (35 years plus)
-increased AMA leads to an increase in conception of multiple births, and an increase in the use of assisted human reproductive techniques
- fertility drugs- one of the many assisted human reproductive techniques
- cryopreservation- freezes the embryos created in IVF
- artificial insemination- injects sperm directly into the woman’s uterus

A

ISSUES IN PRENATAL DEVELOPMENT
(1)Genetic Disorders:

29
Q

ISSUES IN PRENATAL DEVELOPMENT
(3)Teratogens

A

-maternal disease- deviations in prenatal development steaming from teratogens (agents/conditions causing damage to the fetus- cognitive anomalies)
- greatest risk is in the first 8 weeks because this is when most organs develop rapidly

30

A

Fetal Alcohol syndrome which is the leading cause of developmental disabilities in children and also causes distinctive facial features, growth problems (smaller), and problems bonding/attachment

32
Q

What are some examples of Teratogens?
(3)Smoking
B4,⬇️🪨, bd🦠👄,💥🧠🫁
Increase risk of sid the science kid (during ppp)

A

-preterm birth, low birth weight, birth defects of the mouth/lip and increased risk of SIDS (if smoking during the postpartum period) smoking can also damage the fetuses brain and lung devleopment

45
Q

Four Stages of Labor
1.

A

-muscles of the uterus start to tighten (contract) and then relax these contractions help to thin (efface) and open (dilate) the cervix so the baby can pass through the birth canal

46
Q

Four Stages of Labor
2.

A

the cervix is dilated completely (10 cm) and the baby is born

47
Q

Four Stages of Labor

this is the first few hours after birth (breastfeeding etc)
ensure the mother is ok and her uterus contracts to stop bleeding

49
Q

PROCESS OF BIRTH
three stages

A

-during the process of birth some babies go into fetal distress (sudden change in fetal heart rate)
-anoxia (oxygen deprivation) can result in death or brain damage
-after birth most women require a period of a month or so to recover (cap about 10 months)

50
Q

WHAT WE KNOW…

A

-the health of the fetus is impacted long before conception right up until delivery (and beyond) the health influences include
emotional, behavioral, physical, and motor- with long lasting effects

51
Q

• Low birth rate and very low birthdate
◦ Negative effects on mental and motor development (lessen over time)
◦ and growth at 9 months to 2 years of age (growth doesn’t lessen)
• Extremely low birth weight (ELBW) : born less than 2.3 pounds
• Very low birth rate (VLBR): less than 3.9 pounds
• Low birth rate (LBW) less than 5.5
• Normal 5.8-8.13 (average birth rate is 8.7) babies are getting bigger because obesity, we all do c sections not worry about big babies
◦ High birth rate and low birth rate have medical conditions associated with it
