7.1 Immediate Post-Birth Care, Vitamin K, Eye Prophylaxis & Umbilical Cord Care
Key Takeaways
- A vigorous newborn needs warmth, drying, assessment, and skin-to-skin care; suction only when secretions obstruct breathing.
- APGAR describes adaptation and response at defined times but does not decide whether resuscitation begins.
- IM vitamin K prevents early, classic, and late vitamin K deficiency bleeding; refusal requires informed counseling and documentation.
- Dry cord care and assessment for spreading erythema, purulence, malodor, or systemic illness help identify omphalitis.
- HBsAg-positive or unknown maternal status requires time-critical prophylaxis; for HBsAg-negative status, the current U.S. schedule uses shared decision-making about a birth dose.
7.1 Immediate Newborn Care, Prophylaxis & Umbilical Assessment
Core Focus: Support transition first, then complete preventive care accurately. Routine suction and outdated one-size-fits-all immunization language can cause harm or conflict with current recommendations.
Initial sequence
At birth ask whether the newborn is term, has good tone, and is breathing or crying. A vigorous newborn can remain skin-to-skin while being dried, kept warm, and observed. Position the airway neutrally. Do not routinely suction clear or meconium-stained fluid. Clear the mouth/nose only if secretions are obstructing breathing; prolonged or deep suction can cause bradycardia, apnea, tissue injury, and delayed ventilation.
A newborn who is not vigorous moves to a preheated warmer for initial steps and rapid heart-rate/respiratory assessment. Positive-pressure ventilation is the priority for apnea, gasping, or heart rate below 100/min after initial steps; APGAR scoring never delays resuscitation.
Thermal care and identification
Dry the head and body, remove wet linens, use warm blankets and a hat as appropriate, and support uninterrupted skin-to-skin when both patients are stable. Check temperature and glucose risk rather than separating a stable dyad routinely. Apply matching identification and security measures according to policy before leaving the birth area.
APGAR score
Score Appearance, Pulse, Grimace, Activity, and Respiration at 1 and 5 minutes, and continue every 5 minutes through 20 minutes when the 5-minute score is below 7. APGAR communicates condition and response; it is not a diagnosis of asphyxia and is not used to wait for a score before providing ventilation.
Vitamin K
Newborn vitamin K stores are low, placental transfer is limited, and intestinal production is not yet established. IM phytonadione after birth is the most reliable prevention of vitamin K deficiency bleeding (VKDB), including late intracranial bleeding. Administer the product and weight-appropriate dose specified by policy into the vastus lateralis. Confirm medication, concentration, dose, route, consent, and documentation. Oral regimens are less reliable and require multiple doses where used.
Explain that VKDB can occur without warning and that exclusive human-milk feeding increases late VKDB risk because human milk contains little vitamin K. If parents decline, notify the responsible clinician, explore concerns respectfully, document informed refusal, provide explicit bleeding precautions, and follow institutional policy.
Ocular prophylaxis
Erythromycin ophthalmic prophylaxis is intended to prevent gonococcal ophthalmia and is required in many jurisdictions. Apply according to state and facility timing, from inner to outer conjunctival sac without touching the tube to the eye. It does not replace prenatal STI screening or treatment and does not reliably prevent every cause of neonatal conjunctivitis.
Umbilical cord
Confirm that bleeding has stopped and document the vessel assessment when performed. Keep the stump clean and dry, fold the diaper below it, and avoid unapproved substances. Normal separation commonly occurs within the first few weeks. Purulent drainage, malodor with tenderness, spreading erythema/induration, fever or hypothermia, poor feeding, or lethargy requires prompt evaluation for omphalitis. A precise millimeter cutoff is not a substitute for the trend and systemic findings.
Hepatitis B prevention: current U.S. approach
Maternal HBsAg status must be available and acted on:
| Maternal status | Immediate newborn action |
|---|---|
| HBsAg positive | Give single-antigen hepatitis B vaccine and HBIG within 12 hours at separate sites; complete the series and post-vaccination serologic testing on schedule. |
| HBsAg unknown | Draw maternal testing urgently and give vaccine within 12 hours. Give HBIG according to birth weight and as soon as indicated if the result is positive or remains unknown, following the current CDC schedule. |
| HBsAg negative | Since the December 2025 U.S. recommendation, use shared clinical decision-making with the parent about the birth dose. If deferred, begin the infant series no earlier than 2 months under the current schedule. |
Do not delay prophylaxis for an exposed infant while pursuing routine tasks. Verify the exact CDC table for low-birth-weight infants because dose counting and HBIG timing differ. Record product, lot, site, and time and arrange completion and testing.
Family education before discharge
Review cord warning signs, jaundice and feeding follow-up, safe sleep, medication/prophylaxis records, and when the first newborn visit occurs. Use teach-back. Preventive treatment decisions should be documented without stigmatizing families who ask questions or decline an intervention.
Medication and procedure safety
Separate vitamin K, hepatitis B vaccine, and HBIG documentation by medication, concentration, dose, route, site, lot, and time. Use a new syringe and an appropriate needle for each IM product, avoid the dorsogluteal site, and reassess for bleeding or reaction. Verify whether consent or a state opt-out form is required. Delay a nonurgent bath until thermal and cardiorespiratory stability and family preferences permit; bathing is not part of initial resuscitation.
A term infant delivered vaginally has a heart rate of 120 bpm, irregular slow respirations, moderate flexion of extremities, grimace upon bulb suctioning, and pink body with cyanotic hands and feet at 1 minute of life. At 5 minutes, the infant is crying vigorously with active movement, heart rate of 140 bpm, coughs on suctioning, and retains blue hands and feet. What are the 1-minute and 5-minute APGAR scores, and what is the nurse's priority action?
A primiparous mother who intends to exclusively breastfeed states that she wishes to refuse the routine intramuscular vitamin K1 (phytonadione) injection for her term newborn, asking if an oral alternative is sufficient. Which explanation reflects evidence-based physiology and the nurse's clinical counseling priority?
A woman tests positive for Hepatitis B surface antigen (HBsAg-positive) during prenatal laboratory screening. Following an uncomplicated vaginal delivery of a 3,200 g male infant, what is the appropriate immunoprophylaxis protocol and administration timing?
