General overview: Effective nursing care of the newborn infant is based on: (1) knowledge of the conditions present during fetal life; (2) requirements for independent extrauterine life; and (3) alterations needed for successful transition. The first 24 hours are the most hazardous.
- BIOLOGICAL FOUNDATIONS OF NEONATAL ADAPTATIONGeneral aspects:
- Fetal anatomy and physiology
- Fetal circulationfive intrauterine structures that differ from extrauterine structures (Figure 4-11. Fetal Circulation):
- Umbilical veincarries oxygen and nutrientenriched blood from placenta to ductus venosus and liver.
- Ductus venosusconnects to inferior vena cava; allows most blood to bypass liver.
- Foramen ovaleallows fetal blood to bypass fetal lungs by shunting it from right atrium into left atrium.
- Ductus arteriosusallows fetal blood to bypass fetal lungs by shunting it from pulmonary artery into aorta.
- Umbilical arteries (two)allow return of deoxygenated blood to the placenta.
- Umbilical cordextends from fetus to center of placenta: usually 50 cm (1822 inches) long and 1 to 2 cm (½1 inch) in diameter. Contains:
- Wharton's jellyprotects umbilical vessels from pressure, cord "kinking," and interference with fetal-placental circulation.
- Umbilical veincarries oxygen and nutrients from placenta to fetus.
- Two umbilical arteriescarry deoxygenated blood and fetal wastes from fetus to placenta. Note: Absence of one artery indicates need to rule out intra-abdominal anomalies.
- Characteristics of fetal blood
- Fetal hemoglobin (HbF)
- Higher oxygen-carrying capacity than adult hemoglobin.
- Releases oxygen easily to fetal tissues.
- Ensures high fetal oxygenation.
- Normal range at term: 12 to 22 g/dL; average: 15 to 20 g/dL.
- Total blood volume at term: 85 mL/kg body weight; Hct: 38% to 62%, average 53%; RBCs: 3 to 7 million, average 4.9 million/unit.
- Extrauterine adaptation: tasks
- Establish and maintain ventilation, successful gas transferrequires patent airway and adequate pulmonary surfactant.
- Modify circulatory patternsrequires closure of fetal structures.
- Absorb and utilize fluids and nutrients.
- Excrete body wastes.
- Establish and maintain thermal stability.
- Nursing care plan/implementation:
- Facilitate successful transition to independent life.
- Protect infant from physiological stress and environmental hazards.
- Encourage development of a strong family unit.
- ADMISSION/ASSESSMENT: 1 TO 4 HOURS AFTER BIRTH
- Admission assessment of normal, term neonate
- Color and reactivity.
- General appearance, symmetry.
- Length and weight.
- Head and chest circumferences.
- Vital signs:
- Axillary temperature.
- Respirations (check rate, character, rhythm).
- Apical pulse.
- General physical assessment (Table 4-14. Physical Assessment of the Term Neonate ) and reflexes (Table 4-15. Assessment: Normal Newborn Reflexes ).
- Estimate of gestational age (Table 4-16. Estimation of Gestational Age: Common Clinical Parameters ).
- Analysis/nursing diagnosis:
- Altered health maintenance related to separation from maternal support system.
- Impaired skin integrity related to umbilical stump; incontinence of urine and meconium stool; skin penetration by scalp electrode, injections, heel stick, scalpel during cesarean birth; abrasion from obstetric forceps.
- Ineffective airway clearance related to excessive mucus.
- Pain related to environmental stimuli.
- Ineffective thermoregulation related to immature temperature regulation mechanism.
- Nursing care plan/implementation:
- Goal: promote effective gas transport.
- Maintain patent airwayto promote effective gas exchange and respiratory function.
Position: right side-lying, head dependent (gravity drainage of fluid, mucus).- Suction prn with bulb syringe for mucus.
- Goal: establish/maintain thermal stability.
- Avoid chillingto prevent metabolic acidosis.
- Dry, wrap, and apply hat.
- Place in heated crib.
- Monitor vital signs hourly until stable.
- Goal: reduce possibility of blood loss.
- Check cord clamp for security.
Administer vitamin K injection, as ordered, in anterior or lateral thigh muscleto stimulate blood coagulability.
- Goal: prevent infection.
Administer antibiotic treatment to eyes (if not performed in birth room)to prevent ophthalmia neonatorum.- Treat cord stump (alcohol), as ordered.
- Use standard precautions.
- Goal: promote comfort and cleanliness. Admission bath when temperature stable.
- Goal: promote nutrition, hydration, elimination.
- Encourage breastfeeding within 1 hour after birth.
- Check blood sugar (Dextrostix or Chem-strip) at 30 minutes, 1, 2, and 4 hours for infants at risk for hypoglycemia (e.g., SGA, LGA, infant of diabetic mother).
- First feeding at 1 to 4 hours of age with sterile water (or formula) if permissible and if not breastfeeding.
- Note voiding or meconium stool; report if failure to void or defecate within 24 hours.
- Goal: promote bonding.
- Encourage parent-infant interaction (holding, touching, eye contact, talking to infant).
- Encourage breastfeeding within 1 hour of birth, if applicable.
- Encourage parent participation in infant careto develop confidence and competence in caring for newborn.
- Assist with initial efforts at feeding.
- Discuss and demonstrate positioning and burping techniques.
- Demonstrate/assist with basic care procedures, as necessary:
- Bath.
- Cord care.
- Diapering.
- Aid parents in distinguishing normal vs. abnormal newborn characteristics.
- Goal: health teachingto provide anticipatory guidance for discharge.
- Facilitate sibling bonding.
- Describe/discuss normal newborn behavior:
- Sleepingalmost continual (wakes only to feed) or 12 to 16 hours daily.
- Feedingfrom every 2 to 3 hours to longer intervals; establish own pattern; babies who are breastfed feed more often.
- Weight loss5% to 10% in first few days; regained in 7 to 14 days.
- Stools(Table 4-17. Infant Stool Characteristics ).
- Cord carecord drops off in 7 to 10 days
- Keep clean and dry.
- Alcohol may be applied to stump, or it may be allowed to dry naturally.
- HIV precautions.
- Circumcision care
- Keep clean and dry; heals rapidly.
- Watch for bleeding.
- Petroleum jelly, gauze prn, if ordered.
- Do not remove yellowish exudate.
- Physiological jaundiceoccurs 24 to 72 hours after birth.
- Nonpathologic.
- Need for hydration.
- Identify need for newborn screening test after ingestion of milk (done routinely at 24 hours of age and later). Includes screen for congenital hypothyroidism and galactosemia (see Table 11-2. Newborn Screening Procedures,Chapter 11. Reduction of Risk Potential, for other newborn screening procedures).
- Describe suggested sensory stimulation modalities (mobiles, color, music).
- Discuss safety precautions:
- Position on back for sleep.
Infant seat for travel and home safety.- Maintaining contact/control over infant to prevent falls, drowning in bath.
- Instruct parents in infant cardiopulmonary resuscitation (CPR).
Hepatitis B vaccinationfirst dose can be given at 24 to 48 hours of life; second dose at 1 month; third dose at 6 months. If infant born to mother who is infected, hepatitis B vaccine and hepatitis B immune globulin should be administered within 12 hours of birth.
- Describe signs of common health problems to be reported promptly:
- Diarrhea, constipation.
- Colic, vomiting.
- Rash, jaundice.
- Differentiation from normal patterns.

- Breastfeeds well.
- Normal feeding, sleeping, elimination patterns.

- Mother/family evidences bonding.
- Eye contact.
- Stroking, cuddling.
- Crooning, calling baby by name, talking to infant.
