A
baby oxygenation
10
Q
Comprmised perfusion from placenta & umbilical artery affects
A
baby oxygentaion
11
Q
Prolonged O2 deficits leads to
A
Metabolic acidosis => dificult baby transition from fetus to neonate & may even cause permanent neurological damage
12
Q
1st PRIORITY of nurse After Birth of baby
A
Clear Airway
Establish Respirations
prevention of Cold Stress
Cord Blood Collection
13
Q
what does prevention of cold stress have priority over
A
manuel establishment of respirations
14
Q
Cord Blood Collections is necassary for
A
analysis of cord blood gases to determine severity of Acidosis at birth OR for ABO & Rh incompatibility testing
15
Q
Why is the establishment of respiration (PINK) important
A
initiation of 1st breath begins cardiopulmonaty adaptation that MUST occur to transition from placenta-dependent fetus to independent air-breathing neonate.
16

22
Q
Signs of Respiratory Distress
A
Grunting
Retractions
Nasal Flaring
Central Cyanosis
Tachypnea
23
Q
Grunting occurs when
A
Baby tries to keep the alveoli open through partially closed-glottis expiration.
24
Q
Retractions
A
Visible when the baby has to work so hard to inhale that the skin of the chest is pulled against the ribs, making them visible, especially along the lower border.
25
Nasal flaring
Caused by greater force being exerted with inspiration.
26
Central cyanosis
Bluish-color on the face or trunk, pale or dusky color are all signs of poor oxygenation, either from severe anemia, or inadequate respiratory function.
27
Tachypnea in baby
RR greater than 60 breaths/min is compensation to increase oxygen. Its frequently accompanied by tachycardia.
28
Surfactant coats the inner surface of fetal alveoli w/....
surface-active phospholipids lecithin & sphingomyelin
29
Alveolar ducts form
from 20-24 weeks gestation
30
Surfactant production increases from
28-32 wks through delivery
31
What is the needed ration of lecithin/sphinogomyelin to have adequate respiratory function
2:1
32
Risk factors for decrease surfactants
premarute baby & mothers with diabetes
33
T/F: (artificial) surfactant be administerd via an endotracheal tube through the lungs
TRUE
34
T/F: newborn oxygenation jump up right away to 98%
False
35
Whats the targeted preductal O2 saturation in transition
1 min:
5 mins:
10 mins:
1 min: 60-70%
5 mins: 80-85%
10 mins: 85-95%
36
What should you keep in mind when taking pulse ox of newborn
whats normal for them depending their age, may vary bc of shunts depending where you take it
37
When is the APGAR score performed
1 min & 5 mins after birth
38
If APGAR score is below 7 it is done
every 5 mins until a 7 or above is reached
39
APGAR score is used for
measure newborn transition to extrauterine life
40
What do LOW APGAR scores indicate
that the newborn is having trouble with transition (being independent from mom) impacting O2, blood glucose & put infant at greater risk fro physiological jaundice
41
When is the 1st nursing assesment done with a newborn
usually done as the newborn is 1st born
42
1st nursing assessment involves
Color, Respiratory effort, HR, Temp., General appearance,
neurologic, musculo-skeletal
43
When perfoming general survey on a newborn
survey of facial features, body, limbs and genitalia for intactness and function, then skin color, muscle tone and respiratory effort
44
Thermoregulation is
balancing heat loss & heat production
45
When do baby thermoregulate
during the 1st 12 hrs of life
46
Normal temp for infants
97.7 - 99.5
47
What places infants at risk for heat loss
having a larger surface to body ration & thin layers of subcutaneous fat & skin
48
What do baby do to assist in regulating their temp?
may cry & increase muscle activity => increase metabolic activity => increases O2 consumption & glucose consumption
49
what may infants do to decrease surface area
flex their body
50
Can newborn shiver?
Yes some may shiver but its not an effective mechanism for heat production
51
Non-shivering thermogenesis occurs through
metabolism of brown fat & increase metabolic activity in the brain, heart, & liver
52
How do infants produce heat?
by metabolism of their brown fat
53
Brown Fat is located where
the interscapular region, axillae, vertebral column and around the kidneys
54
When can brown fat be depleted quickly
during cold stress
55
Who have a smaller reserve of brown fat
premature babies
56
What are the 4 methods of Heat Loss
Evaporation, Radiation, Conduction, Convection
57
Evaporation is the
loss of heat through moisture (failing to dry infant well after birth)
58
Ratiation is the
loss of heat to cooler objects in the environment not in direct contact (placing crib next to an exterior wall)
59
Conduction is the
loss of heat through direct contact with a cooler object (placing infant on cold surface)
60
Convection is the
flow of body heat from the body surface to cooler ambient air (placing infant near a draft)
61
why is thermoregulation such a major concept in newborn care?
attempt to increase his core temp increases his need for oxygen, then the infant will start breathing faster to compensate for the increased need for oxygenation.
62
drying the infant at birth and placing them under a radiant warmer has priority over
respiratory intervention such as bag and mask resuscitation
63
Neutral thermal environment
Place infant on warm surfaces and use warm blankets
Dry infant well at birth and be sure temperature is 98.0 before bathing
Head cover (hat) & dress in layers
Prevent drafts
Educate parents on cold stress as well as overheating
64
Is an axillary temp of 97.4 a gray area
NO, its too low & needs assessment, take temp under other arm
65
Cold stress is serious in newborns & can result in
DEATH
66
Plasma glucose levels for the 1st few hrs after birth
50-60 mg/dl
67
Plasma glucose levels for the 1st week
60-80 mg/dl
68
What happens when the umbilical cord is clamped?
hint: blood glucose
maternal nurtrition is stopped => * blood glucose will decrease
69
What helps stabilize glucose
initial feeding
70
Hypoglycemia (<45) symptoms
jittery, lethargic, apneic, problems w/ feeding,
seizures,
OR may show NO symptoms at all
71
Risk factors of hypoglycemia
mother is a diabetic, traumatic delivery, cold stress, asphyxia or the infant is LGA, SGA or LBW
Prematurity; have less reserve & usually dont feed well
72
Be proactive w/ at RISK for Hypoglycemia babies by
early feedings, thermoregulation, and decrease energy consumption
73
Whats the typical intervention choice for BG <45 (hypoglycemia)
formula supplementation
74
T/F: Maternal-fetal infection transmission is a major cause of morbidity and mortality in newborns
True
75
Newborns immune system is limited in its ability to ...
recognize, localize & destroy invasive bacteria, allowing infection to go systemic
76
Immature hypothalamus has poor pyrogenic response so ...
temp. instability is more reliable than fever to Dx infection
77
The provider should be notified if the infant is portraying what s/s (early signs)
poor feeding, irritability, vomiting or diarrhea, lethargy, pale or mottled skin color or any symptoms of respiratory distress
78
Newborn risk factors for infections include

prematurity
79
What are the most common infections aquired with prolonged rupture of membranes?
Group B strep & E. coli
80
there is the risk of any organisms in the vagina ascending into the uterus and causing infection if ...
the membranes are ruptured longer than 18 hrs
81
Why are premature babies at greater risk for infection
their immune systems are even more immature than term babies
82
Nursing implications for infections
monitor for early signs
practice asepsis; hand washing for personel & visitors, clean stethoscope/equipment shared
identify infants at risk
