Lowers chance that baby will contract Group beta strep (GBS) given 2 doses
What is Magnesium Sulfate used for in labor and what could happen to newborn?
Pregnancy Induced Hypertension (PIH) could cause hypocalcemia in newborns-newborn will be lethargic(little relfex action)
Why is Vitamin K and Erythromycin ointment given to Newborns?
Vitamin K- given to babies to increase their clotting factor (1mg on admission into thigh w/ 25G 5/8inch TB syringe)

Respirations 30-60, short bursts of apnea, count full minute, nose breathers only
Temp- 36.5C to 37C/ 97.7F to 98.6F axillary ONLY (newborns have poor thermo control…keep warm and watch temperature leads) *DONE RECTALLY 1ST TIME
BP- 80/60 (done normally)
Normal glucose 40-60 done through heelstick
What are Newborn body measurement norms?
Weight average 7.8 lbs
Length average 50 cm/20inches
Head Circumference 32-37cm 12 1/2 to 14 1/2 inches
(Chest and Belly smaller then the head)
When is Rhogam started?
at 28 weeks
What is critical info on Nursery Admission placed on kardex?
- Birth date, time, sex, weight, gestational age, type of delivery
- Blood type; Mother and Baby; Coombs test(positive means mother didnt get enough Rhogam)
- Bonded (Golden Hour)
- Breast of Bottle
- Instructions given
- No formula if breastfeeding as per mom/MD
What is assessed in the nursery including levels/ranges?
Rectal temperature upon admission (never oral, temporal, tympanic) axillary thereafter
Assess Hematocrit 40-70 normal
<40 give blood infusion through umbilical to increase level
>70 contact HCP because of hypercalcemia
> 10 = hyperbilirubinemia/jaundice
phototherapy done
Assess for hypocalcemia caused by meds from labor-baby will be lethargic & flaccid
What are SEPSIS SUSPECT maternal factors?
- Poor prenatal nutrition
- Low socioeconomic status
- Substance abuse
- History of STI’s
- Recurrent abortion
- Prolonged rupture of membranes >12-18 hrs
- Vaginal Group B strep
- maternal tachycardia
- invasive procedures during L and D
- UTIs
- Premature labor
Why and when is metabolic screening done on newborn?
heelstick 24 hours after birth
blood test which works to screen for metabolic conditions (ex: PKU-phenylketonuria)- low Phenylalanine which is amino acid for growth and development
Describe what is done for Hyperbilirubinemia/Jaundice in the newborn.
Phototherapy, using protective eye-ware
- Need sufficient feedings/water to prevent dehydrations
- Exchange transfusions
- Stools green due to release of bilirubin
[85% of preterms have it]
What are Neonatal Factors for Sepsis Suspect?
- Prematurity
- Birth weight <2500 grams
- Meconium Staining
- Need for Resuscitation
- Congenital anomalies
- Males
- Multiples
What are examples of Congenital Malformations minor and major?
Minor- Extra digits, webbing, club foot
Major-neural tube defects (spina bifida, anencephaly)
Down syndrome
Heart defects.
gastrointestinal and kidney malformations.
What are common congenital anomalies?
- Tracheosophageal fistula (trachea and esophagus formed together)
- Diaphragmatic hernia (Bowels where left lung is)
- Omphalocele (Stomach on outside)
- Anencephaly (frog baby- lives few hours)
- Cleft lip and palate(fissure connecting oral and nasal cavity)
- Spina Bifida
- Gastroschisis (intenstines outside babies body)
Where/When is the hearing screen done?
In the nursery before discharge
What are risk factors for late onset hearing loss?
- Family hx of childhood hearing impairment
- Craniofacial anomalies
- Syndrome associated with hearing loss
- NICU admit greater than 5 days
- Mechanical ventilation for more than 5 days
- Hyperbilirubinemia requiring exchange infusion
- Congenital/perinatal infection (syphilis, herpes, etc.)
- Meningitis (bacterial or viral)
- Ototoxic Medications (-mycins)
What are important newborn nursery orders?
- Repeat axillary temp hourly until stable 36.5-37C
- Infant may be bathed when temp greater than 36.5C
- Weight on admission and then daily
- Cord care-apply triple dye to base after admission bath
- If cord bilirubin is greater than 4mg notify physician and begin phototherapy
-Put infant to skin in delivery room as soon as mother if able
- Encourage feeding 8-12 times in 24hrs
- Pacifiers and bottles are discouraged
- Feed non-demanding infants if 4 hours pass
What needs to be verified prior to discharge?
-Infant guardian has car seat, copy of discharge instructions and hearing screen has been done
What is the protocol regarding Hep B with the mother and baby?
Mother negative: give baby Hep B vaccine
Mother positive: give baby Hep B vaccine IM stat and at seperate site hep b immune globulin IM stat
Mother Unknown: give baby Hep B vaccine stat
Describe the Newborn’s head.
-Two fontanels: anterior (closes around 12-18 months) and posterior (closes 8-12 weeks) **if the buldges increase that means ICP. If they decrease in means dehydration.
