Managing Newborn Assessments

Structures the systematic evaluation of a newborn using APGAR scoring, Ballard gestational-age assessment, initial physical examination, and mandated metabolic/hearing screening. Produces a complete birth assessment record suitable for nursery documentation and discharge planning.

Why This Skill Exists

Newborn assessments follow a time-critical sequence: APGAR at 1 and 5 minutes, gestational age within the first hours of life, comprehensive physical exam within 24 hours, and state-mandated screening before discharge. Missed findings at birth — cardiac murmurs, hip instability, undescended testes, metabolic disease — cascade into delayed diagnoses. This skill enforces the AAP-recommended framework so every newborn receives a standardized, auditable evaluation.

Checkpoint A — Intake Verification

Before beginning the assessment, confirm the following are available and complete:

Required Intake Questions

1. What is the maternal obstetric history (G/P, GBS status, maternal labs, prenatal complications)?
2. What was the mode of delivery (SVD, operative vaginal, cesarean) and any intrapartum events?
3. What resuscitation steps, if any, were performed in the delivery room?
4. What is the infant's birth weight, length, and head circumference?
5. Has cord blood been collected for blood type and direct Coombs if indicated?
6. Are maternal hepatitis B, HIV, RPR/VDRL, rubella, and blood type results available?

Required Documents

• Maternal prenatal record with lab results
• Labor and delivery summary including intrapartum fetal monitoring
• Delivery room resuscitation record (NRP documentation if applicable)
• Birth weight, length, and head circumference measurements
• Cord blood lab results (if obtained)

If any maternal lab results are unavailable, flag with [VERIFY] and escalate to attending before discharge planning proceeds.

Step 1 — APGAR Scoring (1 and 5 Minutes)

Score each of the five APGAR components at 1 minute and 5 minutes of life:

Component	0	1	2
Appearance (color)	Blue/pale all over	Acrocyanosis (blue extremities, pink body)	Completely pink
Pulse (heart rate)	Absent	< 100 bpm	>= 100 bpm
Grimace (reflex irritability)	No response	Grimace only	Cry, cough, or sneeze
Activity (muscle tone)	Limp	Some flexion	Active motion
Respiration	Absent	Slow, irregular, weak cry	Good cry

Scoring rules

• Record 1-minute score to assess transition status.
• Record 5-minute score to evaluate response to any intervention.
• If 5-minute score is < 7, continue scoring at 10, 15, and 20 minutes per NRP guidelines.
• APGAR does not guide resuscitation decisions — resuscitation follows NRP algorithm independently.
• Document who assigned the score and their role.

Step 2 — Gestational Age Assessment (New Ballard Score)

Perform the New Ballard Score within the first 12-24 hours of life:

Neuromuscular Maturity (6 criteria)

• Posture, square window (wrist), arm recoil, popliteal angle, scarf sign, heel to ear

Physical Maturity (7 criteria)

• Skin, lanugo, plantar surface, breast, eye/ear, genitalia (male or female)

Interpretation

• Total score range: -10 to 50, corresponding to 20-44 weeks gestation
• Compare Ballard-estimated GA to obstetric dating (LMP, early ultrasound)
• Discrepancy > 2 weeks between Ballard and obstetric dates warrants documentation and attending review
• Classify: SGA (< 10th percentile), AGA (10th-90th), LGA (> 90th) using Fenton or Olsen growth curves for preterm, WHO for term

---

Step 3 — Comprehensive Newborn Physical Examination

Perform the systematic head-to-toe exam within 24 hours of birth. Document each system:

Head/Fontanelles

• Anterior fontanelle size (normal: 1-4 cm diamond), posterior fontanelle (normal: < 1 cm, may be closed)
• Molding, caput succedaneum vs. cephalohematoma (crosses vs. does not cross suture lines)
• Subgaleal hemorrhage screen: boggy diffuse swelling crossing sutures — emergent if present

Eyes

• Red reflex bilaterally (absent = refer ophthalmology urgently for retinoblastoma, cataract rule-out)
• Conjunctival discharge, pupil symmetry

Cardiac

• Precordial activity, heart rate, rhythm
• Murmur present? If yes: timing, grade, location, radiation
• Pre- and post-ductal pulse oximetry per CCHD screening protocol (see Step 5)
• Four-extremity blood pressures if coarctation suspected

Hips

• Ortolani maneuver (reduction of a dislocated hip) and Barlow maneuver (provocation of dislocation)
• Document: stable, clicky (benign ligamentous), subluxable, dislocatable, or irreducible
• Risk factors for DDH: breech presentation, family history, female sex, oligohydramnios

Genitalia

• Male: testicular descent (bilateral? unilateral?), hypospadias, hydrocele
• Female: normal labia, vaginal patency, clitoral size
• Ambiguous genitalia: do NOT assign sex; emergent endocrine consult

Neurological

• Tone: resting posture, pull-to-sit head lag
• Primitive reflexes: Moro, palmar/plantar grasp, rooting, sucking, stepping
• Alertness and cry quality

---

Step 4 — Weight Classification and Growth Plotting

• Plot birth weight, length, and head circumference on appropriate growth chart:
  • WHO growth standards for term infants (≥ 37 weeks)
  • Fenton preterm growth chart for < 37 weeks
• Calculate weight-for-gestational-age percentile
• SGA < 10th percentile — screen for hypoglycemia per AAP protocol (glucose < 25 mg/dL in first 4 hours, < 35 mg/dL at 4-24 hours triggers intervention)
• LGA > 90th percentile — screen for hypoglycemia, assess for infant of diabetic mother (IDM) complications
• Macrosomia (> 4000g term): evaluate for birth trauma (clavicle fracture, brachial plexus injury)

---

Step 5 — Mandated Newborn Screening

Critical Congenital Heart Disease (CCHD) Screening

• Pulse oximetry on right hand (preductal) AND either foot (postductal) after 24 hours of age or before discharge
• Pass: both readings ≥ 95% AND difference ≤ 3%
• Fail: any reading < 90% — immediate echocardiogram
• Repeat: any reading 90-94% OR difference > 3% — rescreen in 1 hour, up to 3 attempts

Metabolic Newborn Screen (state-specific panel)

• Collect after 24 hours of age and adequate protein feeding
• Core conditions (ACMG-recommended): PKU, congenital hypothyroidism, galactosemia, sickle cell disease, CF, CAH, biotinidase deficiency, MCAD, and others per state mandate
• Document specimen collection time, feeding status, and any transfusions (which can affect results)

Hearing Screen

• OAE (otoacoustic emissions) or ABR (auditory brainstem response) before discharge
• Refer failures for diagnostic ABR by 3 months of age per JCIH guidelines
• Risk factors for hearing loss: NICU stay > 5 days, family history, ototoxic medications, hyperbilirubinemia requiring exchange transfusion, CMV

Step 6 — Risk Factor Documentation and Discharge Readiness

Document the following risk assessments before discharge:

• Hyperbilirubinemia risk: pre-discharge bilirubin level plotted on Bhutani nomogram; assign risk zone (low, low-intermediate, high-intermediate, high)
• Feeding adequacy: documented latch assessment (if breastfeeding), stool and urine output, percent weight loss from birth (> 7% by day 3 triggers lactation evaluation)
• Infection risk: GBS status, duration of rupture of membranes, maternal fever, and antibiotic administration per neonatal early-onset sepsis calculator
• Social risk: safe sleep environment confirmed, car seat available, follow-up appointment within 48 hours of discharge per AAP guidelines

---

Checkpoint B — Assessment Review

Before finalizing the newborn assessment record:

• APGAR scores recorded at 1 and 5 minutes (and extended intervals if < 7 at 5 minutes)
• Gestational age assessment completed with SGA/AGA/LGA classification
• Complete physical exam documented with all systems addressed
• Growth parameters plotted on appropriate charts
• CCHD pulse oximetry screening result documented with pass/fail/refer
• Metabolic newborn screen specimen collected with time and feeding status noted
• Hearing screening completed or scheduled with result documented
• Pre-discharge bilirubin plotted on Bhutani nomogram with risk zone assigned
• Feeding assessment documented with weight loss percentage calculated
• Follow-up appointment scheduled within 48 hours of discharge
• All [VERIFY] flags resolved or escalated to attending

Guidelines

• Follow AAP "Guidelines for Perinatal Care" (8th edition) for examination timing and content
• Use NRP (Neonatal Resuscitation Program) 8th edition for delivery room assessment protocols
• Apply the New Ballard Score per Ballard et al. for gestational age assessment
• Follow AAP 2022 hyperbilirubinemia clinical practice guideline for bilirubin risk stratification
• Apply ACMG Recommended Uniform Screening Panel for metabolic newborn screen
• Follow JCIH (Joint Committee on Infant Hearing) 2019 position statement for hearing screening
• Never assign sex when genitalia are ambiguous — immediate endocrine and genetics consultation
• All findings should be documented using precise anatomical terminology, not shorthand
• Escalate to attending physician for any unexpected finding, abnormal screening, or maternal concern
• This skill produces documentation for clinical use; it does not replace clinical judgment
