Careof/HighRiskNewbros Flashcards
What are critical parameters in the initial newborn assessment?
Cardiopulmonary functioning, neuro, musculoskeletal, gestational age (Ballard), birth measurements.
Assessment of the newborn’s transition to extrauterine life. Transition may take up to 12 hours.
When is APGAR scoring done? What do the letters stand for?
1 minute and 5 minutes after birth.
Appearance (color), pulse, grimace (reflex irritability), activity (muscle tone), respiratory effort
Max of 10 points
What are newborn vitals?
Taken every 30 minutes until stable for 2 hours.
Temp: 97.7-99.5
Pulse: 110-160 bpm
RR: 30-60 rpm
How is gestational age measured? When? What makes it up?
Dubowitz/Ballard scoring tool. Within 2 hours after birth.
Physical maturity: skin texture, lanugo, plantar creases, breast tissue, eyes and ears, genitals. Neuromuscular activity: posture, square window (wrist), arm recoil, popliteal angle, scarf sign, head to ear.
How does one perform the immediate interventions of maintain airway potency and thermoregulation?
Suction the mouth and nose with bulb syringe. May just use a towel for term infants.
Regulate environmental temp with a warm room, eliminating drafts or ceiling fans. Stabilize the newborn temp: dry infant immediately, use radiant warmer, warmed blankets. Neutral thermal environment
What medications are immediately administered after birth?
How is proper ID ensured?
Vitamin K to synthesize clotting factors. Erythromycin ophthalmic ointment to prevent ophthalmia neonatorum conjunctivitis.
Mother/newborn ID bracelets (2 on newborn), security band, proper employee identification
What is involved in a head to toe assessment on a newborn?
Skin, head, muscle tone and activity, abdomen, reflexes, safety, parental interaction and teaching
Cyanosis of the hands and/or feet.
Thick white substance that protects the skin.
Milia formed in the mouth
Acrocyanosis
Vernix caseosa
Epstein’s pearls
Salmon patches, superficial vascular areas on the nape of the neck, eyelids, between the eyes, or upper lip.
Unopened sebaceous glands on the nose
Stork bites
Milia
Bluish spots on the lower back and buttock. Usually in the darker skinned population.
Benign papular-pustular rash, usually the 1st week of life
Mongolian spots
Erythema toxicum
Dilation of blood vessels on one side of the body.
These things are usually on he face or other body area. Laser treatment.
These darken with age and disappear by age 3.
Harlequin sign (clown suit) Nevus flammeus (port-wine stain) Nevus vasculosus (strawberry mark or hemangioma)
Elongated head shape to accommodate the birth canal.
Localized edema on the scalp from pressure of birthing process (crosses suture lines)
Molding
Caput succedaneum
Localized effusion of blood beneath the periosteum of the skull (does not cross suture lines)
Soft membranous gaps between skull bones
Fibrous joint occurring only in the skull
Cephalhematoma
Fontanels
Sutures
What are examples of six reflexes that should be seen in an infant?
Sucking, moro (startle), stepping (stepping motion when the infant is held upright), babinski (toes fan out when sole of foot is stroked), grasp both palmar and plantar, rooting
What two reflexes remain from infancy through adulthood?
Gag and coughing
Reflex that when the head is turned to the side the same arm/leg straightens out while the other is flexed with a clenched fist
When prone and the side of the spine is stroked, pelvis flexes toward the stimulated side
Tonic neck (fencing) reflex Truncal incurvation reflex (galant reflex)
The newborn should be fed on demand, when? How is time measured?
Every 2-4 hours.
2-3 hours for breastfeeding, 3-4 hours for formula feeding. Time is measured from the start of one feeding to the start of the next.
Explain feeding of a newborn
Wake at night for feeding if past 4 hours. Assure they’re feeding regularly in the hospital. Burp frequently. Hold bottle-feeding infants. Give vitamin D drops daily. Assure breastfeeding mother has additional 500 calories and 8-10 glasses of water a day.
What are the advantages of breastfeeding over bottle feeding?
Hormones?
Nutritionally perfect for each baby. Contributes to a strong immune system. Encourages bonding. Assists in involution of the uterus. Let down (oxytocin), milk production (prolactin)
What are signs of successful feedings of newborns?
Breasts feel full before and after feedings. Let down reflex occurs. Nurses 10-15 min/breast 8-10 times a day. Swallowing is heard. Baby seems relaxed after feedings. 6-8 wet diapers a day. Stools several times a day. Baby is gaining weight.
Nutrition of the breast milk?
Colostrum for the frist 2-3 days. Rich in immunoglobulins. High in protein, minerals, vitamins. Transitional milk, then mature at 10 days. Foremilk and hindmilk.
Forumla calories? When should they be started on solid food?
10-20 kcal/ounce.
No solids until around 6 months. Double birth weight.
The CDC reccomends that all neonates be vaccinated for hepB when? If mother is negative? Positive?
Within 12 hours.
If mother HbsAg neg, may defer to 1-2 month WCC
If mother HBsAg pos: Hep B dose 1 and HBIG (Hepatitis B immunoglobulin) within 12 hours of birth.
Both given before breastfeeding initiated
What are common tests for genetic and inborn errors of metabolism?
PKU for phenylketonuria. congenital hypothyroidism, galactosemia, sickle cell, thalassemia, SSA. Done at least 24 hours after the first protein feed.
What are newborns classified according to?
Birthweight and gestational age. Variations increase risks for special needs.
Birthweight and gestational age variations?
AGA: Appropriate for gestational age. 10%-90% for gestational age. Lower morbidity and mortality rates
SGA: Small for gestational age. <2500 g (5lbs 8oz) at term. <10% for gestational age (growth charts)
LGA: Large for gestational age. >4000 g (8lbs 13oz) at term. >90% for gestational age (growth charts)
Birthweight variations?
Low birthweight <2500 g (5lbs 8oz) Very low birthweight <1500 g (3lbs 5oz) Extremely low birthweight <1000 g (2lbs 3oz)
Maternal and placental factors that can affect growth?
Maternal: HTN, smoking, diabetes, weight gain, drug use.
Placental: calcification (aging), size, previa/abruption
Fetal factors affecting growth?
Sex (males are larger), multiple gestations, anomalies/chromosomal defects, fetal infection (TORCH)
Assessment findings for a newborn that is small for gestational age?
Disproportionately large head, thin extremities and trunk, reduced subcutaneous fat stores, thin umbilical cord, loose and dry skin.
Identify the fetal growth restriction (FGR). Pathologic counterpart of SGA. At risk for lifelong developmental deficits.
Nursing management of an SGA baby?
Obtain weight, length, and head circumference. Perform frequent serial blood glucose, monitor vitals, assess respiratory status, keep warm. Provide early and frequent feedings, parental education on-going growth follow-up. Screen/observe for polycythemia (Hct >65%)
> 90% on growth chart for age (macrosomia). Risks? Nursing concerns?
Large for gestational age (LGA).
Risks: maternal DM, prolonged pregnancy, previous macrocosmic baby, male fetus, maternal obesity.
Nursing: Traumatic birth injuries, hypoglycemia, hyperbilirubinemia
Assessment findings for LGA babies?
Leave body, appears plump, full-faced, head circumference/body length at upper limits, poor motor skills, difficult to arouse. Sometimes hypoglycemia (<40)mg/dL)2
Nursing management of LGA baby?
Assist in stabilizing. Identify birth injuries: fractured clavicles, brachial palsy, facial paralysis, skull fractures, hematomas, shoulder dystocia. Neuro exam for early intervention of abnormalities. Monitor for hyperbilirubinemia and polycythemia.
Monitor glucose: within 30 mins of birth, qtr, before feeds, PRN. Initiate early and frequent feedings. I/O, weights.
