Test 3 OB Flashcards
Normal HR for neonate is what?
Are blue hands and feet a big deal?
How about heart murmurs?
120-160, 110 and crying is bad
No
No
Is neonatal HgB and Hct higher or lower than adults?
Higher
Neonatal Hgb is 16-18, adults is 10-14
Neonatal Hct is 46- 68, adults is 40-45
Are neonates good at clotting?
No, that’s why we give them K shots
What are the signs of respiratory distress in a neonate?
What is a normal neonatal RR?
nasal flaring
grunting
retractions
30-60
What triggers a neonate to start breathing?
Squeezing of birth
Acidosis
Light/Sounds
Temperature
Surfactants
What are the 4 ways infants lose heat?
Convection - Air takes heat with it
Evaporation - water takes heat with it when it leaves
Conduction - a surface can transfer heat to or from
Radiation - The baby radiates heat- keep the room warm and the baby away from cold walls
How do babies keep warm and why do we care?
Brown fat, not with shivering
Because if they can’t keep warm they get hypoglycemic (shaking twitchy), and respiratory distress (grunting, retractions, nasal flaring)
Normal temperature for a neonate is
36.5-37.5
If a neonate uses its brown fat up:
It uses up glycogen instead
Increases use of oxygen- meatbolic acidosis
Decreases production of surfactant ->
Reverts to fetal circulation
The two types of jaundice in the neonate are what?
Three words to describe physiologic:
Why does it happen?
How do you recognize pathologic jaundice?
Physiologic and Pathologic
Physiologic is common, mild, transient. The infant has an immature liver and it can’t handle the breakdown of all the blood cells. Peaks around day 4-5 and will be gone in two weeks. Never happens the first day.
Pathologic happens the first day of life, because baby and mom’s blood are incompatable and the baby’s blood is breaking down.
What is kernicterus?
Unconjugated bilirubin crossing the blood brain barrier and causing permanent brain damage
What are the newborn reflexes we do in a neonatal assessment?
Moro- the arms out response to dropping
Sucking - they suck on your pinky
Rooting - turn toward stroked cheek
Babinksy - their toes splay when you stroke the foot
Stepping - they slowly take steps when held to the ground
Palmar/Plantar - they grasp whatever is placed in palm or near toes
Fencing- turn their head, their arm goes out
A nurse is preparing a presentation about ways to minimize heat loss in the newborn. Which measure would the nurse include to prevent heat loss through convection?
A. placing a cap on a newborn’s head
B. working inside an isolette as much as possible.
C. placing the newborn skin-to-skin with the mother
D. using a radiant warmer to transport a newborn
B is convection.
a is evaporation,
C is conduction
D is radiation
The nurse places a warmed blanket on the scale when weighing a newborn to minimize heat
loss via which mechanism?
A. evaporation
B. conduction
C. convection
D. radiation
B conduction
The nurse dries the neonate thoroughly and promptly changes wet linens. The nurse does so
to minimize heat loss via which mechanism?
A. evaporation
B. conduction
C. convection
D. radiation
A. evaporation
