1

What is considered preterm gestation?

Less than 37 weeks

2

What is considered preterm gestation?

Less than 37 weeks

3

What is considered gestation?

37 to 42 weeks

4

What is considered post-term gestation?

> 42 weeks

5

What is the neonatal period?

The first 28 days of life (+ preterm time period)

6

What does the perinatal period include?

20 weeks GESTATION to 1 month after birth

7

Where is the ductus venosus?

Connects umbilical vein to inferior vena cava

8

What is the ductus arteriosus?

A channel of communication between the main pulmonary artery and the aorta

9

What is the foramen ovale?

Opening between the two atria of the fetal heart

10

What does the ductus venosus do?

Allows oxygenated blood directly from mom to enter circulation (bypasses liver) via inferior vena cava

11

What does the ductus arteriosus do?

Allows majority of blood which would enter pulmonary vasculature to bypass directly to the aorta

12

What happens with the shunts at birth?

Increased systemic vascular resistance
Decreased pulmonary vascular resistance
Closes shunt and eliminates shunting

13

What happens with the shunts at birth?

Increased systemic vascular resistance
Decreased pulmonary vascular resistance
Closes shunt and eliminates shunting

14

What is considered gestation?

37 to 42 weeks

15

What is considered post-term gestation?

> 42 weeks

16

What is the neonatal period?

20

21

What does the ductus venosus do?

Allows oxygenated blood directly from mom to enter circulation (bypasses liver) via inferior vena cava

22

What does the ductus arteriosus do?

Allows majority of blood which would enter pulmonary vasculature to bypass directly to the aorta

23

What does the foramen ovale do?

Allows oxygenated blood from mom which enters the right atrium to be channeled directly to left atrium and then into the left ventricle, aorta, and system

24

What happens with the shunts at birth?

Increased systemic vascular resistance
Decreased pulmonary vascular resistance
Closes shunt and eliminates shunting

25

What happens to the ductus arteriosus at birth?

Increased oxygen initiates constriction and subsequent closure

26

Asymmetric IUGR

ONLY weight at or below 10th percentile
Head = normal but body is smaller
Late in pregnancy

27

What occurs in the third trimester for the respiratory system?

Surfactant is produced
Surfactant reduces surface tension & stabilizes alveoli
Production sufficient by 34 weeks gestation

28

What needs to be done immediately after birth to help the infant maintain their temperature?

Dry the infant
Provide radiant heat (heating lamp)

29

Growth transition of a neonate

Loss of body weight in the first week
Back to birth weight or more by 2 weeks

30

Parts of the APGAR Scoring System

Activity
Pulse
Grimace (reflex irritability)
Appearance
Respiration
