Q

What causes the IDM to typically be large? (What is going on inside with the glucose and the insulin)

A

Mother- high blood sugars (glucose)
Fetus has ↑glucose in blood, muscle & fat
Fetus converts fat to glycogen & stored

Q

What causes hypoglycemia in IDM after delivery?

A

Fetus produces increased levels of insulin in utero.

Q

What are some potential nursing diagnoses for postterm infants?

A
  1. Impaired gas exchange related to in utero hypoxia or meconium aspiration
  2. Unstable blood sugar levels (hypoglycemia) related to deprived nutrition and limited glycogen stores in utero
  3. Hypothermia related to loss or poor development of subcutaneous fat
  4. Neonatal jaundice related to polycythemia in utero hypoxia
20
Q

What is transient tachypnea of the newborn? (TTN)

A

Progressive respiratory distress

21
Q

What is the etiology of TTN (transient tachypnea of the newborn)?

A

Infant fails to clear airway of lung fluids/mucous. May be caused by aspiration.

22
Q

What is the incidence of TTN?

A

11/1000 live births

23
Q

A

C-section, LGA, late preterms, intrauterine or intrapartum asphyxia

24
Q

Rate >60-120 per min

25
Q

26
Q

How long does mod/severe TTS last?

A

27
Q

28
Q

What is the definition of Meconium Aspiration Syndrome (MAS)?

A

Meconium aspirated into the tracheobroncial tree during labour/delivery

29
Q

What is the etiology of Meconium Aspiration Syndrome (MAS)?

A

Asphyxia -> increased peristalsis and relaxation of anal sphincter -> aspiration at birth

RN to implement algorithm as per hospital policy (blood sugar and feeds)

Limit infant activity (eg. bath) until stable blood sugars

If unable to perform skin to skin, bundle babe in warm shirt, flannel and hat

Teach mom and partner re temp control and how to dress her baby
Once stable ensure a warm environment during bath. F/U temp 1 hour post bath
Ensure frequent feeds and STS

Refer to MD/pediatrician if problems
Teach parents about “what to expect and how to care for problem prior to discharge”
Refer to PHN on discharge PRN

44
Q

What are some nursing actions for risk for neonatal jaundice (hpyerbilirubinemia)?

Assess behaviour (wake-sleep pattern) q shift
Assess I&O Q3h
Assess for signs of dehydration (decrease skin turgor, fontanelles, eyes) Q3h
Teach parents re signs of jaundice, when to seek out help and community resources prior to discharge

45
Q

What are some nursing actions for risk for impaired parenting related to delayed attachment/anomalies?

A

Assess maternal-child/parental attachment q interaction
Assess maternal affect q interaction

Explore situation and feelings re:infant and hospitalization
Refer to professional resources (social worker, public health nurse) prior to discharge
