Study Notes
Birth Weight Variations
- Small for Gestational Age (SGA): Babies born at term (40 weeks) with a weight less than 2500 grams (5.5 lbs) or below the 10th percentile on the growth chart.
- Large for Gestational Age (LGA): Babies born at term (40 weeks) weighing more than 4000 grams (8.8 lbs) or above the 90th percentile on the growth chart.
- Risk Factors for LGA: Diabetes mellitus, history of LGA babies, maternal obesity, high weight gain during pregnancy.
- Characteristics of LGA babies: Large body size (proportionate), plump head, poor motor skills, less reactive, higher risk of birth injuries (fractured clavicle, shoulder issues, nerve paralysis), at risk for hypoglycemia.
- Hypoglycemia in newborns: Anything less than 40 mg/dL is concerning. Look for symptoms like jitteriness, tachypnea, drowsiness, low tone, and temperature instability.
- Nursing Management of LGA babies: Frequent blood sugar checks, monitor for birth injuries, and provide support with feeding difficulties due to poor motor skills.
Pre-Term Newborn
- Born before 37 weeks gestation.
- Increased risk of mortality and morbidity due to immature body systems.
- Typically weighs 2500 grams (5.5 lbs) or less.
- Respiratory System: One of the last body systems to mature, making preterm infants at high risk for respiratory complications. Low surfactant production can lead to apnea, cyanosis, grunting, nasal flaring, and retractions.
- Cardiovascular System: Preterm infants may still have a fetal shunt that needs to close after birth, potentially leading to a heart murmur.
- Gastrointestinal System: Lack of neuromuscular coordination can cause difficulty sucking, swallowing, and breathing simultaneously, leading to insufficient calorie and fluid intake. Enteral feedings can help mature the intestines but require careful monitoring.
- Immune System: Preterm infants have less of a chance to receive maternal antibodies as most transfer occurs at week 34.
- Central Nervous System: Preterm infants at increased risk for temperature instability.
- Nursing Assessment of Preterm Infants: Lack of flexion, limited rugae on scrotum, lack of creases on feet, covered in vernix, fused eyelids, and poor muscle tone.
- Nursing Management of Preterm Infants: Promote oxygenation, maintain thermal regulation, prevent infection, and provide enteral or parenteral nutrition.
Post-Term Newborn
- Born beyond 42 weeks gestation.
- Nursing Assessment: Dry, cracked, peeling skin, absence of vernix and lanugo, long and thin extremities, wide-eyed alert expression, abundant hair on scalp, thin umbilical cord, long fingernails, meconium-stained skin and fingernails.
- Nursing Management: At risk for asphyxia due to an aged placenta and lack of amniotic fluid, hypoglycemia due to depleted stores, hypothermia due to less fat stores, and polycythemia (increased RBCs) leading to a higher risk of jaundice. Monitor for signs of respiratory distress, check glucose levels, maintain temperature, and provide frequent feedings.
Acquired Disorders
- Perinatal Asphyxia: Decreased ability for gas exchange. Causes can include maternal respiratory issues, placental insufficiency, and cord issues.
- Rapid Newborn Assessment: Color, breathing effort, heart rate, and temperature.
- Resuscitation Management: Effective ventilation is key.
- Transient Tachypnea of Newborn: Self-limiting condition often associated with C-sections and the lack of "thoracic squeeze" during vaginal delivery.
- Nursing Management: Monitor for respiratory distress, supplemental oxygen, and IV fluids.
- Respiratory Distress Syndrome: Inadequate production of pulmonary surfactant, leading to difficulty keeping the lungs open and increased energy expenditure for breathing.
- Nursing Management: Prevent preterm birth, maternal corticosteroids to enhance fetal lung development, surfactant replacement therapy, ventilation, and blood gas monitoring.
- Meconium Aspiration Syndrome: Presence of meconium in the lungs, causing mechanical obstruction of airways, potential for pneumothorax and bacterial pneumonia.
- Nursing Management: Maintain temperature, high oxygen, high-pressure ventilation, and prophylactic antibiotics.
Retinopathy of Prematurity
- Potentially blinding retina disorder. More common in preterm infants, especially those with very low birth weight.
- Risk Factors: Prematurity, supplemental oxygen leading to hyperoxemia (elevated oxygen levels), hyperoxemia causing vasoconstriction and rupture of blood vessels in the retina.
- Prevention: Avoiding prematurity.
Necrotizing Enterocolitis
- Bacterial invasion of the intestinal wall, leading to inflammation and cell death.
- Risk Factors: Preterm infants.
- Nursing Assessment: Cardiorespiratory changes, feeding intolerance, abdominal distension and tenderness, bloody stools, respiratory distress.
- Nursing Management: Fluid and nutritional status, supportive care, antibiotics, and possible surgical resection.
Infant of Diabetic Mother
- Often LGA, ruddy (excessive red color), macrosomic, and have excessive adipose tissue.
- Pathophysiology: Exposure to high levels of glucose in the mother, leading to increased insulin production by the fetus and increased glycogen storage.
- Management: Prevent hypoglycemia (symptoms include slow mental development, vomiting, poor feeding, irritability, musty urine).
- Preventive measures: Screen all newborns, dietary restrictions, regular monitoring of phenylalanine levels.
Birth Weight Variations
-
Small for Gestational Age (SGA): infants weighing less than 4000 grams (at term) or below the 10th percentile on growth charts
- Risk Factors: diabetes mellitus, history of LGA babies, maternal obesity, high weight gain during pregnancy
- Common Characteristics: large body (proportionate), plump head, poor motor skills, less reactive, higher risk for birth injuries (e.g., fractured clavicle, shoulder issues, nerve paralysis)
- Hypoglycemia Risk: frequent blood sugar checks are essential, signs include temp instability, jitteriness, tachypnea, drowsiness, low muscle tone
- Hypoglycemia Threshold: anything less than 40 mg/dL in newborns
-
Pre-term Newborn: born before 37 weeks gestation
- Higher risk for morbidity and mortality due to immature body systems
- Typically weighs 2500 grams or less
- Respiratory System: last body system to mature, prone to complications like apnea, cyanosis, grunting, nasal flaring, and retracting
- Cardiovascular System: transition to extrauterine life requires a well-functioning respiratory system, PDA may remain open (heart murmur)
- Gastrointestinal System: lack of neuromuscular coordination for suck, swallow, and breathe, leading to insufficient calorie and fluid intake, ischemia, and damage to the intestinal wall
- Immune System: majority of maternal antibody transfer occurs at week 34
- Central Nervous System: at higher risk for temperature instability
-
Post-Term Newborn: born after 42 weeks gestation
- Characteristics: dry, cracked, and peeling skin, absence of vernix and lanugo, long and thin extremities, wide-eyed alert expression, abundant hair on scalp, thin umbilical cord, long fingernails, meconium-stained skin and fingernails
- Risks: Asphyxia due to aged placenta and lack of amniotic fluid, hypoglycemia, hypothermia, polycythemia, and jaundice
- Nursing Management: monitor for respiratory distress, check glucose levels, maintain temperature, frequent feedings
Acquired Disorders
-
Perinatal Asphyxia: decreased ability for gas exchange
- Risk Factors: maternal history of respiratory issues, placental insufficiency, cord issues
- Nursing Management: rapid newborn assessment at birth (color, breathing effort, HR, temperature), resuscitation management, effective ventilation
-
Transient Tachypnea of Newborn (TTN): self-limiting respiratory distress
- Cause: failure to clear lung fluids and debris, often associated with Cesarean deliveries without thoracic squeeze
- Nursing Management: monitor for respiratory distress (tachypnea typically presents within 6 hours), chest x-ray, supplemental oxygen, fluid and electrolyte management with IV
-
Respiratory Distress Syndrome (RDS): inadequate production of pulmonary surfactant
- Characteristics: cyanosis, nasal flaring, grunting
- Nursing Management: prevention of preterm birth, maternal corticosteroids for enhanced fetal lung development, postnatal surfactant replacement therapy, ventilation, blood gas monitoring
-
Meconium Aspiration Syndrome (MAS): presence of meconium in the lungs
- Complications: mechanical obstruction of airways, risk of pneumothorax, bacterial pneumonia, inactivation of surfactant, significant respiratory distress
- Clinical Manifestations: hypotonia, low heart rate, fetal hypoxia, low APGAR scores (1-5)
- Nursing Management: maintain temperature, high oxygen, high-pressure ventilation, prophylactic antibiotics
Retinopathy of Prematurity
- Possible cause of blindness
- Retina disorder primarily associated with prematurity and very low birth weight
- Also related to newborns receiving supplemental oxygen (can develop hyperoxemia - high oxygen in blood)
- Prevention: avoiding prematurity
Necrotizing Enterocolitis (NEC)
- Bacterial invasion of the intestinal wall leading to inflammation and cell death
- High risk in preterm infants
- Nursing Assessment: cardiorespiratory baseline changes, feeding intolerance, abdominal distension and tenderness, bloody stools, respiratory distress, signs of sepsis
- Nursing Management: fluid and nutritional support, supportive care, antibiotics, possible surgical resection
Infant of Diabetic Mother (IDM)
- Characteristics: LGA (Large for Gestational Age), ruddy complexion (excessive red color, high RBCs), macrosomic, excessive adipose tissue
- Pathophysiology: fetus exposed to high levels of glucose, leading to increased insulin production and glycogen storage
-
Management: prevention of hypoglycemia (signs: slow mental development, vomiting, poor feedings, irritability, musty urine)
- Screening: mandatory for all newborns
- Dietary Restriction: phenylalanine levels must be monitored regularly
