88
Q

As pregnancy progresses, insulin secretions _________ to compensate, and insulin production __________ by the 3rd trimester

A

Increase; doubles

89
Q

Why does insulin production and secretion increase during pregnancy?

To ensure that glucose is going to the baby for fuel

90
Q

As a result of large amount of circulating glucose diverting to the fetus, the mother will

A

More quickly dip into glucose stores for fuel

91
Q

Behaviors of normal pregnancy

A

Mild fasting hypoglycemia, progressive insulin resistance, hyperinsulinemia, mild postprandial (after eating) hyperglycemia

92
Q

Why does a pregnant women experience mild fasting hypoglycemia?

A

Due to the overproduction/elevation of insulin which will drop blood sugar

93
Q

Significance of mild postprandial hyperglycemia in pregnancy

A

Mild postprandial hyperglycemia increases the amount of time of elevated maternal glucose level and increases the flux of maternal nutrients to the fetus

94
Q

During the first trimester of pregnancy, the need for insulin is _________

A

Decreased

95
Q

During the first trimester of pregnancy, estrogen and progesterone levels _________

A

Increase

96

99
Q

During the second and third trimester, insulin need is __________

A

Insulinase

102
Q

Why do insulin requirements often decrease dramatically during labor and delivery?

A

Decreased food intake (decreased need for insulin), increased metabolism and workload for labor (labor is considered a workout which eliminates the need for insulin)

103
Q

Postpartum behaviors

A

Significant decrease in hormones (HPL, progesterone, estrogen), increased insulin sensitivity (after separation of placenta), further decreased insulin requirements with breastfeeding

108
Q

How does maternal diabetes influence RDS in fetus/neonate?

A

High levels of fetal insulin inhibit an enzyme needed for surfactant production

109
Q

How does maternal diabetes influence neonatal polycythemia/hyperbilirubinemia?

A

Due to diminished glycosylated hemoglobin to carry oxygen

110
Q

How does maternal diabetes influence neonatal hypoglycemia?

A

After maternal blood glucose is cut off, high levels of insulin activity deplete glucose levels leaving newborn at risk

111
Q

Maternal antepartum diabetes medical management goals

112
Q

113
Q

Maternal antepartum glucose monitoring

A

3-4x a day

A

Broken clavicle and nerve damage

161
Q

Birth trauma increases the risk for

A

Newborn jaundice

162
Q

Newborn polycythemia pathophysiology

A

Fetal hyperglycemia and hyperinsulinemia = increased O2 consumption; glycosylated hemoglobin binds to O2, decreased amount of O2 available to fetus which stimulates production of erythropoietin and RBCs. Increased RBCs increases Hct which increased risk for hyperbilirubinemia

163
Q

RDS occurs particularly in

A

Infants of poorly controlled diabetic mothers

164
Q

RDS pathophysiology

A

Fetal lungs are less mature than expected for gestational age due to insulin antagonizing synthesis of lectin, and decreased phospholipid phosphatidylglycerol levels

165
Q

Protein needed for lung maturation and surfactant production

A

Lectin

166
Q

Lipid needed for surfactant stabilization

A

Phospholipid phosphatidylglycerol

167
Q

RDS nursing consideration

A

Test for lung maturity prior to delivery if before 39 weeks
